Abstract
Continuous filter centrifuges (CFCs) are used in the food, chemical and other industries. This type of machines is designed for separation of suspensions with undissolved solid phase, dehydration of crystalline and granular products, classification of materials by size, clarification of low concentration suspensions. Centrifuges of this type are also used for the separation of suspensions with a solid phase, particle size 5-74 microns and a volume content of 5-30%. A characteristic constructive feature of such centrifuges is a drum in the form of a hole rotor. When analyzing the process of suspensions separation into the CFCs quantitatively, it is necessary to take into account the flow structure, the kinetics of sediment formation on the rotor wall, the condensation of the liquid system being treated, and the particle size variation of the slurry. The aim of the work: from the viewpoint of the theory of the similarity of physical processes, using the example of the centrifugal separation of the third product's massecuite, to analyze quantitatively the kinetics of sucrose crystals isolation from the sugar-containing solution and dehydrate this solution in the working volume of the continuous filter centrifuge. The mechanical and geometrical parameters of the centrifugal equipment of the CFCs type, as well as the physicomechanical and dispersion characteristics of the liquid system being treated, were considered as the basis for the initial positions of the process under study. This allowed quantitative analysis of the kinetics of isolation from the sugar-containing solution of medium-dispersed sucrose crystals on the basis of physical and mathematical modeling, as well as to calculate the process of dehydration of this solution in the working volume of a continuous filtering centrifuge. As the controlling parameter of the process, the coefficient of clarification - the synthetic (integrative) index of the severity of the separation of the liquid system was used. As a result of a numerical experiment on the analysis of the dependence of the clarification coefficient on the productivity of a centrifuge on equipment of the FVI-1001K-1 type, data similar to those observed in a real centrifuge were obtained.

Abstract
The imperfection of the mixing technique affects the quality of products. The process of mixing the components is among the most energy-intensive, positively influencing the quality of finished products and shelf life. The mixer, having three chambers, through which pass two shafts, while the high speed shaft located in the first chamber, is installed inside the low-speed shaft. The design feature of a mixer is a z-shaped working blade, located on the fast shaft, which improves the process of mixing the components. On a high-speed shaft after the Z-shaped blades are two tape spirals of different diameter with opposite winding, providing a direction of flow of the mixture toward each other in a cross-counterflow. Working bodies (cone-shaped blades and band spirals) are three kinds of the movement of the mixture in the mixer: tangential, radial and axial flow. Mixer allows to optimize the mixing process of raw materials, different in grain-size composition and physical properties, due to the rational character of the movement of the mixture in each working chamber depending on the functional purpose of the product. In addition, expanding the scope of the mixer due to the achievement of the universalization of the mechanism of mixing taking into account characteristics of physical and mechanical properties of initial components. In addition, decreasing the duration of the technological cycle of obtaining ready mix, and hence reduce the specific energy consumption of the mixing process in achieving a better homogeneity of the finished product.

Abstract
In this paper, we propose a mathematical model of the process of changing the productivity of a membrane, both through the formation of a continuous gel layer, and by blocking individual pores. Also, the results of modeling the process of dia- ultrafiltration (DUF) purification of pectin solutions and their concentration by ultrafiltration (UF) using hollow fiber membranes are presented. The effect of periodic washing of the membrane and the process of gelation along the membrane on the productivity of the plant was studied. Thus, the process is characterized by two parameters, and A is the main parameter of the problem, which is the same for all stages, and the second parameter, the ratio (k =F0/F'), characterizes the degree of pore purification with a general cleaning of the membrane surface and is thus one from the characteristics of a single cycle. The valuesof a number of parameters are determined experimentally. It is shown that when the system of differential equations, represented in the normal Cauchy form describing the given technological process, is jointly solved, the productivity of the DUF system can be increased by the frequency of flushing. The conducted experiments demonstrated the advantage of the use of the DUF process in the production of pectin and the features of purification and concentration of apple and sunflower pectins in this process. It is established that the use of DUF causes the introduction of an energy-saving technological process in the production of pectin to produce the target product that meets the required quality and environmental safety of production. The introduction of the proposed methods of DUF and UF into the production of pectin leads to an improvement in the quality and cost of the product.

Abstract
Beet pulp is the main sugar industry by-product obtained with traditional production technology. It has high nutritional qualities, but in its raw form it turns sour quickly so it must be preserved. One of the most common methods is drying. Drying of the beet pulp with superheated vapor of reduced pressure in the pulsating vibro-boiling layer allows to improve the quality of the finished product by lowering of the drying agent temperature, thereby retaining a significant amount of nutrients in the initial product. To study the kinetic and hydrodynamic dependencies of the drying process, an experimental apparatus was developed that makes it possible to obtain the most accurate and reproducible results. In the course of the work, a lot of experiments were carried out. Drying curves, drying rate curves and heating curves were made based on these experiments results. According to the nature of the changes the corresponding conclusions were drawn. To study the interaction of various factors affecting the beet pulp drying process, the mathematical methods of experiment planning are applied. A mathematical description of this process can be obtained empirically. At the same time, its mathematical model has the form of a regression equation, determined by statistical methods on the basis of experiments. As a result of statistical processing of experimental data, regression equations were obtained that adequately describe the beet pulp drying process in a pulsed low-pressure vibro-boiling layer in the experimental apparatus. With reference to this drying apparatus, such technological modes of its operation were determined that ensure a minimum specific energy consumption of the drying process per kilogram of evaporated moisture and the maximum drying chamber moisture stress.

Abstract
The work is aimed at investigating the rheological properties of the ferment in the process of maturation and storage with subsequent determination of the rational parameters of its drying in various drying plants with the analysing of microflora of dried samples. We studied the rheological properties of the ferment using the strain of the lactobacilli L. Acidothilus 146A (activator) and without it, which showed that the ferment for the production of special purpose bakery products to non-Newtonian or anomalously viscous liquids described by the Osthald-de-Vale rheological equation. We found that the introduction the strain of the lactobacilli L. Acidothilus 146A helps to reduce the viscosity during maturation by almost 3 times, and when storing the samples – in 2 times, this is indicated by the value of the consistency coefficient. The activator reduces the influence of temperature, so the structure of the ferment becomes more stable. It is easier to further process in this state. Consequently, the energy consumption for production is significantly reduced and the increases expiration date after the strain of the lactobacilli L. Acidothilus 146A is added to the starter for the production of special purpose bakery products. We detected kinetic patterns of drying of the activated ferment in thermoradiation, convective and sublimation dryers under different temperature operating conditions. We have determined the rational parameters of drying the ferment for the production of bakery products of specialized purpose. We analyzed the useful microflora of the dried samples. It has been revealed that microorganisms undergoing convective and sublimation (freeze drying) are subjected to the smallest destructive effect. We found that microorganisms are less destroyed by convective and freeze drying. The microbial titer in these samples is at least 1(105CFU/g. While drying by the method of infrared irradiation, this titer is lower by a factor of ten compared to other types of drying considered. Taking into account that the temperature of the process is not destructive for starter microorganisms, it is most likely that the reduced survival of the microflora is due precisely to the radiation activity of the infrared lamps. As a result of the conducted studies it was revealed that the optimal type of drying for the ferment is convective.)

Abstract
It is necessary to know the basic hydrodynamic parameters of the material layer for proper organization of oats drying and roasting in fluidized mode, as well as when dryers and roasting plants designing. They serve as a good evaluation of the structure of the layer and contribute to the determination of optimal modes of coolant supply, in which a greater mobility of the material particles in the layer is created. The hydrodynamic characteristics of the fluidized layer were determined from the change in the resistance of the layer, depending on the vapor velocity and the specific load of the product on the gas distribution grid, as well as on the change in the height of the fluidized material layer, depending on the vapor velocity and the height of the fixed layer. The study was carried out in the following ranges of technological parameters: air temperature 343-373 K, steam temperature 383-413 K; the flow velocity of the coolant at the entrance to the layer is from 1.8 to 3.0 m / s; specific load of the product on the grate is from 15 to 30 kg / m2. The fluidization speed of oat grain, porosity and pressure loss of superheated steam in the fluidized layer of the material were determined. The deviation of the experimental data from the calculated data did not exceed ±18%. Graphic dependencies of the degree of expansion and homogeneity of the oat grain layer were obtained. It was shown that an increase in the specific loading of the oat layer on the grate contributes to the formation of a more homogeneous structure of the fluidized layer. Analysis of uniformity and equality of fluidization of a monodisperse layer of oats allows to evaluate its quality and to choose the optimal hydrodynamic regime for the drying and roasting process.

Abstract
To describe complex projects or various jobs that make up a set of interrelated activities, use the network schedule. Several variants of network models are used. 1. For practical use, the Gantt chart is the most widely used - it is a graphical representation of consecutive intervals of time and the use of resources. 2. The network graph is represented as a graph, where the vertices are an event (or its state at a certain point in time), and the connecting arcs (or edges) are works. The graph model is used in the work. In this case, the events (the fact of the completion or the beginning of the work) correspond to the vertices of the graph, and the work to the arcs, the orientation of which corresponds to the technology of this process. An important role in the project management model is played by the optimal assignment of performers to the existing list of works. With this formulation of the problem, the total implementation time or the length of the critical path on the graph can be used as a criterion. In this case, the criterion is imposed a restriction on the deadline for the execution of work (or the project as a whole). Thus, the total time spent on the project and the length of the critical path are represented by equally important characteristics of the project implementation, and they should be considered as two equivalent criteria for the multicriteria project management task. We have proposed an algorithm, in general, an approximate determination of the set of Pareto-optimal solutions of a given problem.

Abstract
Тhe work is dedicated to the development of a method of automated medical diagnosis based on the description of biomedical systems using two parameters: energy, reflecting the interaction of its elements, and entropy characterizing the organization of the system. The violations of the energy-entropy cycle of biomedical systems is reflected in the symptoms of the disease. Statistical link between the symptoms of the condition of the body and the nature of excitation of its elements best expressed in the heuristic description of the system state. High accuracy classification of the patient's condition is achieved by using heuristic detection methods. In the proposed approach, allowing to estimate the probability of correct diagnosis increases the accuracy of the classification, and the estimated minimum amount of training samples and the capacity of its constituent signs. Classification technique consists in averaging the characteristic values in the selected classes, the preparation of the complex of symptoms of the most important signs of the disease, to conduct a "rough" diagnostic threshold rules that allow to distinguish severe forms of the disease, then differential diagnosis the severity of the disease. The proposed method was tested for classification of the forms of puerperal endometritis (mild, moderate, severe). The training sample contained 70 case histories. Syndrome to classify the patient's condition was composed of 17 characteristics. Threshold diagnosis has allowed to establish the presence of disease and to separate heavy. Differential diagnosis was used for classification of mild and moderate severity of postpartum endometritis. The accuracy of the classification of forms of postpartum endometritis amounted to 97.1%.

Abstract
The article is devoted to the method of experimental estimation of parameters of functioning of standard information protection systems from unauthorized access, certified, widely used in organizations operating automated information systems. In the course of the experiment, statistical data were evaluated in the dynamics of the functioning of information security systems against unauthorized access in automated information systems. Registration of the parameters for the execution time of protective protection functions was carried out using a special utility called ProcessMonitor from the Sysinternals suite of utilities used to filter processes and threads. The loading of the processor and main memory of the computer with the use of special software, specially designed for performing experimental research, simulates the operation of GIS in real-world work for its intended purpose. A special software for simulating the work of a system with high load is developed in "VisualStudio 2015" within the framework of "ConsoleApplication". At the same time, the processor is loaded at a level of 50-70% and 60-80% of the operative memory. The obtained values of the time of implementation of protective functions in conditions of high utilization of resources of computer facilities for their intended purpose will allow us to assess the conflict and dynamic properties of the GIS. In the future, the obtained experimental estimates can be used to develop a model of information security in automated information systems, as well as in the formation of quality requirements (resource intensity, response time to the user's request, availability, etc.). Also, the results of the computational experiment in the future can be used to develop a software package for assessing the dynamic performance of information security systems against unauthorized access in automated information systems

Abstract
The article considers the constructing problem of the food industry journals aggregate ratings. The streamlines of the seventeen magazines on four bibliometric indexes (SCIENCE INDEX, five-year impact factor RISC given the translated version without self-citations, h-index over 10 years and Herfindahl index), which are used in the scientific electronic library elibrary.ru was used as initial data. The statement of the problem refers to multi-criteria decision-making problems. Ranking the journals in these indexes are different from each other because bibliometric indicators account different aspects of the journals. The classical approach to thisproblems solution is based on generalized criterion building in the form of an additive convolution. However, this approach requires adherence to a number of regular conditions that may not always be performed when the practical problems solution. The reductionspossibility of the considered formulation in the form of multi-criteria decision-making tasks to the problem of collective choice. The aggregated ratings of the reporting journals are calculated by using the three social choice rules – Board procedure, Copeland procedures and Kemeny median heuristic procedures. On the basis of Spearman's rank correlation determined the quantitative evaluation of the degree of intimacy built in magazines. In particular, calculated on the basis of procedure, Board and Kemeny median aggregate ratings reporting in the logs coincided. The results showed that the constructed ordering of journals on the basis of social choice rules are in good agreement with the scientific electronic library (eLIBRARY) bibliometric indicators.

Abstract
The choice of research direction is related to the actual problem of production and distribution of functional purpose food products due to the spread of nutritional diseases and the lack of micronutrients in ordinary people and athletes diet. As an object for enrichment with iodine, it was suggested to use lentils, which is famous for its high protein content, low lipid and oligosaccharide content, and low inhibitory effect. The iodine accumulation occurs during germination, due to the use of a nutrient solution of the iodine inorganic form. In addition, the biochemical composition of the grain and the biological value of lentils are significantly improved: an increase in the content of total amino acids and vitamins is found to be 1.5-2.0 times, a mass fraction of the oligosaccharide fraction is observed. To determine the effect of technological processing on the degree of iodine conservation in lentils the grains were exposed to the following impact: grinding, extrusion, frying. An insignificant decrease in the amount of iodine during extrusion was noted and more significant one - during grinding. The obtained results of the determination of biological safety by the method of studying the effect of the investigated product on the growth response of ciliates allowed to confirm the safety of both fresh and dried sprouted grain of lentils. When studying the microbiology of grain by sowing on agarized selective diagnostic environments with subsequent identification of the qualitative and quantitative composition of microflora, including colony-forming units, deviations from the normative indices were not revealed. Experimental production of the extrudate was carried out, possible ways of its use in meat systems for improving the functional and technological properties of minced meat, as well as for independent use as snacks for the nutrition of athletes were suggested.

Abstract
In the technology of flour confectionery products non-traditional types of plant raw materials can be used. Introduction of muffins of pumpkin and flour from whole wheat seeds, rich in vitamins and microelements, will enrich muffins with useful substances and increase their nutritional value. The purpose work was to study the technological properties of enrichers, their chemical composition, as well as to study the efficiency of using pumpkin pulp in the recipes of cupcakes and to identify its rational dosage. In this work, conventional methods of investigating the properties of finished products have been used. The object of study were ready-made muffins with different dosages of pumpkin pulp. The rational dosage was established by examining organoleptic (taste, smell, surface, fracture appearance, structure and form) and physicochemical parameters (moisture mass fraction, density, specific volume and alkalinity). The result of this work is the development of a new recipe and production technology for the cake "Ilya Muromets" with the addition of 50% pumpkin pulp to the mass of flour. The addition of the enrichant in the formulation contributed to an increase in the density of the product by 21%, a decrease in the specific volume by 16.7%. Calculation of the nutritional value of the developed product showed that due to the rich chemical and vitamin composition of the pumpkin pulp, the consumption of 100 g of cake will provide a degree of satisfaction of the daily protein requirements by 6.9%, fat 16.2%, carbohydrates – 9.2%, dietary fiber 7.2%. With the help of the received data it is possible to characterize the "Ilya Muromets" cake as a product of increased nutritional value for preventive and functional nutrition that will allow expanding the assortment of products on the bakery market.

Abstract
The article presents the results of studying the chemical composition of mullards duck meat in comparison with the ducks of the Beijingg white breed and musk ducks. The chemical analysis results allow us to note the high moisture content for mullard duck meat. The low fat content for white and red mullard duck meat opens up wide opportunities for the development of an assortment of meat products with a functional orientation. The limited amino acids are determined. The total number of essential amino acids in the mullard duck meat is higher than in musk (by 1.02 g / 100 g protein) and Beijingg (by 0.86 g / 100 g protein), which indicates a higher biological value. The limiting amino acid is methionine and cysteine. The article presents the results of the raw material aroma assessment using the "MAG 8" - "electronic nose" analyzer. The content of easily volatile compounds in the equilibrium gas phase for samples of muscle and fat tissue from ducks of different breeding was compared and evaluated. The most informative in the matrix are sensors with films of polydiethylene glycol succinate, polyvinylpyrrolidone, polyethylene glycol PEG-2000, 18-crown-6, trioctylphosphine oxidase, which show maximum sensitivity to polar and nitrogen-containing compounds, aromatic hydrocarbons. This is explained by the fact that the easily volatile fraction of both meat and fat of the samples under study is represented by a variety of organic compounds of different concentrations. Such a variety of substances can be perceived by tasters as "a noticeable smell, difficult". In accordance with the results obtained, we concluded that the aroma of muscle and fat tissue of mulard ducks is more intense, more saturated than the Beijingg duck. The obtained data on the chemical composition indicate possible dietary properties of meat of ducks of mullards. The rich, pronounced aroma of muscle and fatty tissue causes high organoleptic parameters of the finished product, which is extremely important for the consumer. Meat of mulard ducks is interesting for meat products production due to its high biological value.

Abstract
Osmotic dehydration has recently received more attention as an effective method of preserving fruits and berries. Osmosis is a simple process that facilitates the processing of fruits and berries in order to preserve the original characteristics, namely nutritional value and organoleptic properties: color, aroma and texture. Osmotic dehydration has found wide application in the preservation of food products, as the activity of water in fruits and berries decreases, in some of them up to 90% of water is contained. The process of osmotic dehydration with the help of various agents is less energy-intensive than the process of drying or freezing, since it can be processed at ambient temperature. Osmotic dehydration has potential advantages in preserving the quality of food and in maintaining healthy food for the food industry. Treatment includes dehydration of fruits and berries by an osmotic agent followed by dehydration in dry or frozen apparatus where the moisture content decreases and the product becomes more stable. This process is a partial dewatering process to provide improved product quality compared to conventional drying processes or freezing. The purpose of studying osmotic dehydration is to identify the advantages and disadvantages in the treatment of osmotic agents. Various aspects of osmotic dehydration technology are considered, namely the solutions used, the characteristics of solutions, the effect of variable processes and the qualitative characteristics of osmo-dehydrated products. Factors of osmotic dehydration that depend on the osmotic agent, concentration of solute, temperature, time, size, shape and compactness of the material, mixing and the ratio of the solution to the samples.

Abstract
One of the biggest challenges is to find ways of recovering the expensive powder. With this aim, we needed to find out what happens with polyamide powder in the chamber of the printer and what processes affect raw materials, thereby impairing the physico-mechanical properties. In order to answer these questions, we conducted a number of studies. Articles of mixtures with a high aspect ratio of the secondary powder lose their properties: their surface is rough, increased fragility, there is a possibility of deformation of details. We carried out studies of the powder based on polyamide-12, applied by JSC "Center of technological competence of additive technologies" of the city of Voronezh, brand PA2200 modified. Material white powder, odourless. An increase in the degree of crystallinity from recycled polymer is considered an anomaly. But the violation of this trend due to the peculiarities of the technology of selective laser sintering. Thus, prolonged exposure of the powder in the chamber at a temperature close to the melting point, followed by a long cooling to room temperature represents the ideal conditions for the growth of crystalline phase. The research was able to identify differences due to deterioration of the physico-chemical properties of the powder after processing. The most important is the agglomeration of particles of the secondary powder in relation to the primary. In this regard, powder, already passed the stage of processing, an increase in the melting temperature, which causes defects in the fabricated parts: as the capacity of the carbon laser melting powder particles is fixed, its energy is not sufficient for the occurrence of the endothermic reaction caused by melting of the secondary powder. Thus, the powder particles only partially fused, whereby the resulting products of the observed increase in fragility.

Abstract
To develop boron deficiency treatment composite preparations for significant agricultural crops tris(2-hydroxyethyl)ammonium complexes containing boron and lower dicarboxylic acid (C2-C4) anions were synthesized and characterized. It was shown, that formation and stabilization of complexes containing a greater number of carbon atoms or intermolecular ?- conjugation (e.g. maleic acid) is related to space and electrostatical hurdles, respectively. According to NMR spectroscopy, in case of tartaric acid complex vicinal hydroxyl bounding with boron was found. The preexisted boratrane azeotropic water distillation synthetic method was modernized (videlicet optimal solvent mixture and raw materials ratio were chosen). Various triethanolamine and boric acid reaction mediums, i.e. nonpolar (toluene), polar aprotic (dimethylsulphoxide), protic (isopropanol, 2-butanol) solvents and their mixtures, were tested. In the issue optimal synthetic method, utilizing isopropanol/2-butanol mixture in ratio 3 to 1, was elaborated. In comparison to standard azeotropic water-isopropanol distillation the yield of the process was exceeded to 12.08% (from 82.70% to 94.78%) and low impurity concentrations in product was committed. Besides alternative laboratory solvent-free boratrane synthetic method was developed and optimal rinsing fluid composition was found. During agricultural experiments substance effectiveness in germination power and germinability of beet seeds and productivity of sugar beet was studied. Boratrane was found to be slightly effective for seed germinability stimulation. Boratrane-containing composition (i.e. boratrane + tris(2-hydroxyethyl)ammonium o-cresoxyacetate + 1-chloromethylsilatrane) was shown to have the best results in apical root length, average root-crop and average plant weigth increasing in comparison with the control.

Abstract
The structure of alpha-amino acids offers the possibility of the formation of a large number of forms coordination compounds with cations of metals All forms of amino acids can participate in complexation reactions with metal cations: protonated form with metal ions adducts by coordinating with unshared electron pairs of oxygen atoms of carboxyl groups, the stability constants of such complexes are small and they usually like solvate complexes; bipolar and deprotonated forms not only adducts, but also chelation. The study of equilibrium in the system of amino acid - metal cation are most often carried out potentiometric and spectrophotometric methods, allowing fast, with good reproducibility to determine the equilibrium concentration and composition of the solution without displacement of the chemical equilibrium. In the literature, a chelate compound of leucine with copper (II) cations, formed in an alkaline medium with stability constants of 7.89 and 6.45, has been studied in sufficient detail. This paper presents a study of the conditions of complex formation in neutral aqueous solutions in the system containing aliphatic amino acid L, D-leucine and copper cations (II). The difference in the wavelengths corresponding to the maximum optical density indicates a change in the composition of the aqueous solution and the presence of copper leucinate compounds. The existence of a complex compound between bipolar leucine ions and copper (II) cations in neutral aqueous solutions of the composition (СuLеu4)2+ was proved by the spectrophotometric method of isomolar series. For the determination of stability constants using the method of J. Bjerrum with the following assumptions: an amino acid was regarded as monobasic weak acid, the stability constant of complex compounds was calculated as the average of all functional groups of leucine. Defined in the work a measure of stability constants protonated compounds composition (СuLеu4)2+ is equal to 4.27.

Abstract
The paper presents the results of research of technology of alkylation of hydroquinone, propyl, isopropyl, isobutyl and tert-butyl alcohols in the presence of concentrated phosphoric acid. The temperature of the alkylation reaction was maintained between 70–72 °С. On the basis of literature data and preliminary investigations the reaction was performed for 4 hours. Upon completion of the reaction, we removed the unreacted hydroquinone, aliphatic alcohol and phosphoric acid are added to a solution of distilled water (solvent corresponding connections) and sodium bicarbonate to slightly acidic (pH 5–6). For separation from the reaction medium of alkylhydroquinones in the reaction mixture was added benzene in which the original hydroquinone dissolves much less. Concentration of the benzene extract alkylhydroquinones conducted by Stripping the solvent under vacuum at temperatures above 70 °С in air atmosphere. Higher temperature vacuum distillation AIDS in the oxidation of alkylhydroquinones to alkylphenones. Precipitated after crystallization, alkylhydroquinones were dried under vacuum in a drying pistol at 56 °С. Dried products were identified by defining the melting temperature, the study of spectral characteristics and qualitative reactions with FeCl3. We also studied the solubility of alkylhydroquinones in various solvents, which showed low solubility of alkylhydroquinones in water, benzene, toluene and higher solubility in propyl and isopropyl alcohols and in acetone. Analysis of the results shows that the obtained alkylhydroquinones are not chemically pure compounds, and contain in their composition of admixture source of hydroquinone. Qualitative reactions of solutions of alkylhydroquinones with FeCl3 solution differ from the corresponding reaction of a solution of hydroquinone. The results of investigations of electronic absorption spectra of alkylhydroquinones and source of hydroquinone in isopropyl alcohol solution did not significantly differ from each other and have a maximum absorption at ? = 210 nm. From the presented investigations it follows that the maximum efficiency of the alkylation of hydroquinone was studied aliphatic alcohols in acidic medium is observed for t-butyl alcohol.

Abstract
The results of research on the problem of regeneration of rubbers based on butyl rubber are presented. The advantages of radiation destruction of butyl rubbers are substantiated. The diaphragms of the vulcanizer formers, which were exposed to ionizing radiation at the Co60 source, were chosen as the objects of the study. The effect of the irradiation dose on the technological properties of the recovered regenerates and the elasto-strength properties of the compositions based on them was studied. It is established that the treatment of diaphragm rubbers with a dose of 50, 70 kGy provides an optimal set of properties. An analysis of the structural changes that occur during irradiation of spent diaphragms showed that at high doses of 20-40 kGy a high level of high-elastic deformation remains, while a sufficient number of crosslinked structures remain. At an irradiation dose > 40 kGy, the destructant acquires the ability to roll. The effect of machining on diaphragm rubbers subjected to radiation exposure has been studied. It was found that processing on rotor-type equipment reduces the viscosity of the compositions. The procedure for optimizing the composition of roofing rubber compounds was performed depending on the irradiation dose of diaphragm rubbers and the dosage of the regenerate. Regression statistics and variance analysis confirmed the adequacy of the model and the significance of the coefficients of the equation. The error in the calculations for the tensile strength was 0.65%, for the MI viscosity, 1.23%. On the basis of the developed regenerants, roofing rubber compounds were made and their properties were investigated. It is shown that the use of butyl rubber regenerants in a recipe of roofing rubbers with a dose of 50, 70 kGy provides the required level of properties and reduces their cost price. It is recommended to use these materials in the composition of hydro-insulating materials to improve technological properties and reduce their cost.

Abstract
Transmission electron microscopy (EM) is the way to control structure of lipid nanoparticles. Our work was aimed at study of EM imaging of nanoparticles based on mixtures of dioleoylphosphatidylcholine (DOPE) and phosphatidyl acid (PA), and phosphatidylcholine (PC) and cholesterol (Chol), using contrasting with uranyl acetate (UA), and phospho-tungstic acid (PTA). Suspensions of nanoparticles DOPE/PA (9:2) and PC/Chol (1:1) were adsorbed on formvar film, 1 min, and contrasted with UA, or PTA (pH 0.5), or PTA (pH 7.0), 5-10 sec, then studied in EM Jem-1400 (Jeol, Japan). Spectra of 31P-NMR of samples were recorded on spectrometer AV-300 (Bruker, Germany). Nanoparticles DOPE/PA, UA and PTA (pH 0.5) contrasting: rounded particles, formed by filaments (2-3 nm) of low electron density (ED). Filament morphology corresponds to structures of inverted hexagonal phase (IHP). PTA (pH 7.0) contrasting leads to filament structuring and appearance of membrane-like structures, morphologically corresponding to lamellar phase (LP). However, 31Р-NMR analysis revealed in sample spectrum single signal on 0,189 m.d. (IHP). Nanoparticles PC/Chol, UA and PTA (pH 0.5) contrasting: irregular particles, formed by filaments (2 nm), low ED, corresponding to IHP. The PTA revealed stacks of lipid bilayers in preparation, corresponding to LP. Presence of lipid different phases is confirmed by 31Р-NMR: analysis of preparation spectra, showed LP (signal -0,482 M. D.), IHP and isotropic phase (signals on -0,235, -0,362 M. D.). Thus, EM allows to identify lipid phase state; “traditional” contrasting agents differently identify components in same preparation, suggesting their active interaction with lipid molecules, and indicates necessity of using different contrasting for visualization of lipid nanostructures.

Abstract
Microbial enzyme preparations are increasingly replacing conventional chemical catalysts in a number of industrial processes. Such drugs, in addition to environmental friendliness and high activity, have a number of advantages over enzyme preparations of vegetable and animal origin, namely: the production of microbial enzymes in bioreactors is easily controlled and predictable; excreted microbiological enzymes are more stable than intracellular animals and plant enzymes; the genetic diversity of microorganisms makes it possible to produce enzyme preparations with a wide range of specificity; microbiological enzymes can be synthesized year-round, in contrast to the production of plant enzymes, which is often seasonal. The leaders of the world market of enzymes are proteases and amylases, which account for 25% and 15%, respectively. Over the past five years, the world market for carbohydrases, including mainly amylases, cellulases and xylanases, has been the fastest growing segment of the enzyme market with an aggregate annual growth rate of more than 7.0%. Another major product of the industrial enzyme market, which has a great potential for growth, is lipases. From the point of view of designation, the main part is represented by food and food enzymes. The Russian market continues to be unsaturated - the current supply is not able to meet the needs of the Russian feed and food industry in enzyme preparations. Enzyme preparations of domestic producers are in demand in forage production, while food industrial enterprises prefer imported products. The most significant enterprises in the enzymatic industry in Russia at the moment are Sibbiofarm, AgroSistema, Agroferment. In the light of the Russian policy of increasing food security, the development of the domestic enzyme industry is an extremely topical task.

Abstract
One of the promising areas of biotechnology is the bioconversion of plant raw materials, an example of which is solid-phase cultivation: the cultivation of microorganisms and higher fungi on plant raw materials in order to obtain biologically active substances, for example, cellulases. At the moment, there are data on studies on methods of enhancing the cellulase activity of microorganisms by modifying nutrient media: the addition of vitamins, minerals, bioregulators. In this work, strains of microorganisms of the genera Bacillus, Alternaria, Trichoderma were used. These microorganisms are capable of biodegradation of cellulose and were obtained from the All-Russian Collection of Microorganisms. These cultures of microorganisms are planned to be used as destructors of cellulose in sunflower meal. Appinee (2,4-epibrassinolide) and heteroauxin (?-indolylacetic acid) bioregulators were used as amplifiers of cellulolytic activity. To determine the cellulolytic activity, the Hutchinson medium method with the addition of 10 g / l of carbomethylcellulose was used, and the ability of the Congo-red dye to form a complex with cellulose. The diameter of the bleaching zone around the wells served as an estimate of the presence of cellulolytic activity. It was found that the appine bioregulator in the dilution 10-1 showed the greatest increase in cellulolytic activity. Further solid-phase fermentation was carried out on a medium based on sunflower meal. After analyzing the data obtained during the experiments, it can be concluded that the stimulant appine and heteroauxin have a positive effect on the cellulolytic activity of Alternaria alternate, Trichoderma reesei, Bacillus subtilis, with the maximum effect being on appine

Abstract
In the technology of traditional and new forms of food, the modification of structure of proteins is carry out in two opposite directions: the hydrolytic destruction of high-molecular polymers and the artificial creation of polymeric structures of high molecular mass. The transglutaminase preparations (protein-glutamine (-glutamyltransferase, EC 2.3.2.13, TG) are used in practical work for realization of the second direction. The main mechanisms of action are polymerization reactions, which lead to a change in the hydrophobicity of protein molecules. The main catalyzed reactions are acyl transfer, binding between glutamine and lysine residues of proteins and deamination. The authors analyzed the approaches to the preparation, properties and studied the joint effect of temperature and pH on the activity of the commercial preparation Revada TG 11 with the application of an enzymatic colorimetric test. The authors studied combined stuffing systems based on beef, pork, poultry mechanical deboning, as well as replacing part of the raw material with protein-carbohydrate compositions with Revada TG 11. The results were used to develop simulated meat systems of biopolymer compositions (SMSBC), approximate in structure and properties to the gels formed by actin and myosin during extraction from myofibrils under the traditional technological processes of meat products production - maturation, salt curing, fine meat grinding. SMSBC includes lupine flour bio-activated by germination, a preparations of dietary fiber as well as a preparation of transglutaminase Revada TG 11. The protein components of the secondary raw materials during the processing of milk such as sodium caseinate, and also whey were used to balance the amino acid composition of the food systems. For practical use, the following options for SMSBC introducing into the composition of minced meat emulsions were recommended by the authors: in the form of hydrated biopolymer dispersion at cutting; in the form of a previously heat-treated gel.

Abstract
Silage is the main juicy food and a source of vitamins for animals in the winter-stall period. In order to expand the range of forage crops for the production of high – protein silage in the work used non-traditional forage culture amaranth, which is the content of protein balanced by the number of essential amino acids (especially lysine, methionine and tryptophanus), oils, micro – and macro-elements, vitamins and biologically active substances far superior to traditional forage plants, including legumes. Amaranth belongs to the group of plants hard-ensilage because the level of sugar in its green mass does not exceed the minimum required for the silage process, but the use of starter cultures, contributing to the creation of optimal conditions for the normal flow of fermentation processes, can solve this problem. The comparative characteristic of qualitative indicators of a silo from amaranth paniculate and from maize as raw materials of the most widespread for preparation of green forages is carried out in work. It is established that in the phase of milk-wax ripeness of seeds amaranth has the best technological properties for silage harvesting, as the total loss of nutrients in the silage of amaranth in this phase is minimal. The content of "raw" protein, which is an important indicator in the conditions of protein deficiency in traditional fodder crops, in the amaranth silage of paniculata is almost 2 times higher than in the corn silage. Based on the evaluation of the quality of silage on dry matter content, organic acids, crude protein, degree of acidity and organoleptic indicators it can be concluded that the silage of amaranth is more balanced in terms of key indicators of quality compared to corn silage.

Abstract
There has been a significant increase in requests for recognition of the debtor insolvent, this situation actualize proactive crisis management in combination with low rehabilitation potential of the institution of bankruptcy since 2014. The crisеs in the development of enterprises are inevitable, moreover it can have positive aspects, for example, increase the company's susceptibility to progress and prevention of more serious crises, so the main objective of proactive crisis management isn`t the avoidance of crisis but optimization of the crisis process. Optimization of process involves the correlation of the costs of implementation of preventive measures and available resources to allocated resources are sufficient for implementation of all phases of proactive crisis solutions, but at the same time, the company has not incurred unreasonably high costs. The authors conducted a comparative analysis of definitions of “proactivecrisis management” and specified the content of this concept. The adoptionprocess of proactive crisis solutions should be clearly structured, so the authors highlighted and discussed in detail the process of adoption of proactivecrisis solutions, which includes 4 stages: obtaining information about the internal and external enterprise environment, the stage of processing the gathered information and taking necessary proactive crisis decisions, the implementation of the adopted decisions and control their implementation.Modern tools of proactivecrisis management are varied and take into account the specifics of modern Russian system of market relations, because they include analysis of internal and external enterprise environment, quantitative and qualitative indicators. The authors suggest to consider innovation as one of the possible instruments of preventive crisis management.

Abstract
The article analyzes the interaction of economic components of culture and of valuable components of the economy in the institutional environment. The analysis of interaction based on basic postulates of the behavioral economy. Following a number of Russian researchers the author comes to the conclusion that the culture economy can influence the dynamics of productivity and labor efficiency. The author based on the institutional approach, and he introduces “the traps of cultural degradation” and “cultural multiplier” concepts which are forming in the institutional environment. Spending of budget reduction on culture in the long time may lead to deformation of one's own cultural traditions and institutions. In the article offers a theoretical construct for interaction between the economy of culture and culture of the economy based on the concept of economic mentality. The author includes in the definition the value-motivational attitude to work, wealth, norms and patterns of established economic behavior, the national orientation of the economic agent and his assessment of his subjective economic wellbeing. The author argues that the low culture of economic interaction causes significant damage to the quality of market transactions through the growth of opportunistic behavior of economic agents, economic crimes, and so on. Opposite tendencies associated with the fixation of the theaters and museums visiting per 1000 people growth while reducing the average per capita monthly household income are revealed. In order to understand whether this is a trend characteristic of national economic mentality, or this is a feature of the demand for cultural goods, which is characteristic for them without national binding, the author suggests that a similar analysis for other countries of the world. The author comes to the conclusion that the economic mentality of economic agents should contribute to the development of charity and philanthropy institutions as an additional source of investment in the sphere of culture.

Abstract
The article examines the issues of administrative culture, its relevance and formation of the foundations of this culture in future heads of educational institutions. Changes in the life of society reveal many problems. Most of them are connected with the search for mechanisms that increase the effectiveness of social processes regulation, including their management. In conditions of change, there is a great need for a leader capable of implementing such management, which is aimed at harmonizing personal values and meanings, rights and duties of team members, and harmonizing relations among the participants in the process. The notion of "management culture" is opened and a literary review on the work of Russian and foreign teachers is made. According to the authors, management activities require specific personal qualities, since management is always connected with people and can be directed both to oneself and to another person or group of people. As a research task, the authors defined an attempt to assess the problem of forming a management culture among undergraduates as future heads of educational institutions. Described work experience aimed at developing their reflective sphere as the basis of administrative culture. Authorship and approbated questionnaires were used during the research. Diagnostic materials are presented, as well as a special questionnaire related to determining the level of formation of the foundations of a management culture among undergraduates of pedagogical areas of training. The dynamics of work with undergraduates is traced and a comment is given, taking into account the peculiarities of the direction of master's training. The image of a successful leader with the eyes of undergraduates of future heads of educational institutions was also defined.

Abstract
The development of a modern economy, increasing its competitiveness is impossible without the accumulation and development of human capital, since the foundation of the transformation of the economic system into an innovation economy is human capital. In this regard, the level of development and effectiveness of the use of human capital is of paramount importance. In this study, an attempt is made to assess the effectiveness of the use of human capital for its contribution to the economy of the country. The authors emphasize that the modern economy makes new demands on workers, therefore it is necessary to constantly accumulate human capital, its development through continuous training, which will allow the domestic economy to exit on the trajectory of sustainable economic growth. The need to create conditions for a comprehensive increase in the level of development of human capital was stressed. The authors propose an author's approach to assess the level of development and efficiency of the use of human capital on the basis of indicators: the index of labor productivity, the share of high-technology and knowledge-intensive industries in GDP, the increase in the number of high-productivity jobs, the innovative activity of organizations, the share of domestic expenditure on research and development in GDP, the coefficient of inventive activity. The article presents the results of the study of human capital in the Russian Federation. The role of human capital in the economic development of the country has been studied and justified. Key indicators of the effectiveness of the use of human capital are analyzed. Trends in the development of human capital in the Russian Federation for 2011–2016 are shown. The analysis of the results of the assessment will reveal problems in the formation and use of human capital and determine the main directions and necessary conditions for increasing the contribution of human capital to the economy.

Abstract
One of key questions of support of the enterprise economic safety is assessment of a level of closeness to bankruptcy. There are several known methods of such assessment among which the method of the scoring analysis considering the principles of creation of the modern expert systems and giving a rating assessment of a financial status in general is selected. However the task of search of a method of the preliminary express assessment allowing to gain quickly an impression about financial status is relevant. It is offered to use for this purpose the generalized liquidity indicator – the rating number using the most informative signs of solvency and liquidity (an index of the general solvency, absolute liquidity index, coefficient of the current liquidity, a share of reverse assets in balance, coefficient of a covering of current assets by SOS). Weight factors of rating number (vector of priorities) are defined by the modern method of the analysis of hierarchies of T. Saati. Data of balances of ten domestic enterprises for which financial coefficients of solvency and liquidity are calculated are provided. After their normalization by boundaries of normal restrictions new variables – signs of liquidity, proceeding from a condition of the maximum informativeness are entered. The generalized liquidity indicators for the researched enterprises are calculated and are compared to the results of scoring financial analysis in general expressed as the score of profitability of the cumulative capital, coefficient of the current liquidity and coefficient of autonomy. Correlation analysis of a level of closeness of results of both methods on the basis of Pearson and Spirmen's criteria is carried out. Close correlative connection of the received results is established (Pearson's correlation coefficient k = 0.799, coefficient of grade correlation of Spirmen ? = 0.824) that allows to recommend calculation of the generalized liquidity indicator as the preliminary express valuation method of a financial status.

Abstract
The development of the Russian economy cannot be separated from the world tendencies. The research conducted by foreign and Russian scientists form the essential basis for further comprehensive analysis. The presence of individual features in the Russian economy determines the importance of ongoing scientific work, both from the theoretical and practical points of view. Meanwhile, there is a lack of methodological writings. This fact determines the necessity to study the integration aspects using methodological approaches. The foundation of the methods that implement the functions of the state for the support of innovation activity made it possible to substantiate the role of innovative resources such as knowledge and information in the formation of the environment of innovation. In this regard, we formulated the strategies of resources’ provision for innovation activity, analyzed them and specified the problems of modern Russian economy that influence the integration engagement of the economic entities. The obtained findings determine the number of conditions for the renewal of economic and social systems and allow us to draw a number of conclusions. The effectiveness of the internalization of knowledge for the commercialization of innovations and the development of the integration processes of the system of resources’ provision for innovation activity is determined by the evolutionary and informational factors. The synergy of such processes will be seen in the increase of management efficiency in the system of resources’ provision for innovation activities at the subregion level and the rise of weight of innovative resources into the economic growth of the country's innovative economy. The evaluation of the current processes will be more reliable if a private innovative strategy is chosen, considering as well the integration engagement of the economic entities and the nature of globalization in the modern economy. These conclusions substantiate the priorities for further innovation process of the Russian economy to succeed in the medium and long terms.

Abstract
In this article it is suggested a model of organization of project management in the field of innovative projects. The article notes the approach to innovation as an economic-psychological phenomenon, on the basis of which, an interdisciplinary approach to the organization of management in the field of organizing innovation activity is proposed. It is analyzed the content of innovation activity. As the result it is underlined two main stages: the stage of economic creativity, which includes the emergence of the idea and the preparation of the initial plan, and further implementation of the activity with its further adjustment. The first stage begins with the emergence of the idea of the main participant of the process - the innovator. At the first stage, the selection and justification of the necessary resources for the realization of this idea takes place. The result of this stage can be formalized in a clear work plan, the content of the description of resource resources. The second stage is essentially a non-innovative activity, but an economic one. The proposed interdisciplinary approach takes into account not only the economic component and the effectiveness evaluation, but also the psychological features of the generators of ideas – «innovators», innovation activity and institutional environment. The described model includes the hard core of the innovator team, as an auxiliary belt, which includes psychological, technical, economic and legal support services. Particular emphasis is placed on psychological techniques that allow optimizing and stimulating the process of innovation. As the basic receptions of psychological support are noted motivational conversations, creation of banks of ideas, positive reinforcement and facilitation. The proposed model will reduce the bureaucratic burden primarily through the connection of technical personnel responsible for preparing the necessary technical documentation. Secondly, the reduction in bureaucratic burden is possible due to the definition of the most precise timeframe and the criteria for assessing the result.

Abstract
The basis for innovative development of the agroindustrial complex is the goals, principles and methods that determine the economic security of the region. The category of “economic security”is often identified with the sustainability, competitiveness and risk-free economy of agricultural and processing enterprises. Ensuring the economically safe functioning of all industries and spheres of regional agribusiness is impossible without interconnection with science and education. The most important principles necessary for the formation in the regional and national agribusinesses of a developed economically secure market of scientific, technical and innovative products for agroindustrial purposes are the following: providing the scientific and research sphere of the agro-industrial complex with highly qualified personnel; ensuring real freedom and independence in the activities of research institutions; the formation of a common interdependent economic space and interest; organization of specialized market structures in the field of research and innovation development; development and application within the regional agro-industrial complex of a scientifically grounded economic mechanism for regulating the functioning and stimulating the development of the market for scientific and technical innovation products. Purposeful development of the civilized market of scientific, technical and innovative products of agro-industrial design with its corresponding structures and organizational-economic mechanism is an objective necessity of functioning of economic security of the national economy. The interests of the economic and food security of the region and the state as a whole need to increase the financing of the agricultural sector and the processing industry to a level that will overcome the investment and innovation crisis caused by sanctions. To this end, we believe it is necessary to finance the innovative investment agrarian fund at the expense of budget funds, as well as the participation of market agents: commercial banks, business structures, private investors.

Abstract
This paper is dealing with the irradiated foods world market quantitative and economic volume' estimating in 29 countries. The irradiation exposure technology development is presented in order to prospects in Russia. The main irradiated foods categories such as spices, herbs, dry vegetables, fruits, frozen and chilled meat, including frog legs, seafood, grains and others are identified. It is shown the quantitative dividing irradiated foods world market is between China (37,60%), USA (19,36%), Ukraine (14,74%), Vietnam (12,41%), Brazil (5,62%), South Africa (4,10%), Indonesia (1.30 percent), Japan (1,17%), Belgium (1,10%). The remaining 20 States took a share of 2.6%. The irradiated products world market’ economic volume amounting to 17,136.56 million rubles, is divided between the USA (48,64%), China (16,26%), Brazil (14,53%), South Africa (of 10.18%), Vietnam (of 5.88%), Indonesia (1,04%). The remaining 24 countries took a share of 3.48% while share each of them amounting less than 1%. It is revealed that the most expensive irradiated foods’ category is "spices and herbs", least – "vegetables", "cereals". The research results are shown the Russian potential irradiated foods volume consisting of meat products, the main vegetable crops, food ingredients, spices and food is about 10 million tons, more than 12 million tons, about 200 thousand tons per year respectively. The meat and poultry total production was 9,899.2 thousand tons in carcass weight, yield of grain and leguminous was 120,671.79 thousand tons; spices raw was 97.5 thousand tons, potatoes was 31,107.80 thousand tones, vegetables (excluding melons) was 16,283.34 thousand tons, forage crops (except grasses) was 27,674.15 thousand tons in 2016 in Russia. Therefore 100% of meat, 74% of vegetables and about 1% of spices and animal feeds may be subjected to radiation in Russia. Despite the advanced technology and status as a leader in the agricultural radiology and radioecology field commercial irradiation is not carried out in Russia due to the need for in-depth irradiated foods' influence study of biochemical, physical-chemical, molecular-genetic processes in the human body and the representatives of agrobiocenosis.

Abstract
At different stages of economic development interest in terms of improvement of innovative activity on the part of researchers is different. It is mediated by the level of economic development: if in the beginning of XX century, foreign researchers, problems of economic development based on innovative activities are considered as processes of innovation, the classical theory of economic development with the creation of favorable conditions for rational activity was due to the individualistic behavior of the subject when an individual keeping in mind only their own interest, to pursue their own benefit. But supporters of Keynesianism showed that a stable growth rate in the economy is ensured by the use of factors of production, i.e. full utilization of the workforce with a combination of guaranteed and natural factors. Post-Keynesians (John Robinson, N. Kaldor, L. Pasinetti and John Krigel), suggested his own concept of economic development, which was based from the point of view of development of innovations in the factors of the combination of technological progress and institutional factors. Modern researchers enabling environment improvement innovation associate them with technocratic and industrial development. Development. At the same technocratic development includes the development of technical and intellectual processes in the economy. Conditions of improvement of innovative activity is a complex interaction between the innovators (enterprises, laboratories, research institutes, educational institutions, individuals), investors, manufacturers of competitive products (services) and infrastructure of their interaction among themselves and the market. The main condition for all these factors of improvement of innovative activity are investments.

Abstract
The article defines methods of managing innovation risk in the tourist business. A travel company that implements an innovative strategy of its activities faces special risks that accompany innovation: low demand for innovative services due to lack of information about them, and lack of feedback from consumers of these services; underestimation of the cost of the innovation service; the appearance of so-called problematic innovations, etc. The aim of the work is to study the features of the functioning of the tourism market, as well as to identify problems and prospects for the development of tourism using innovations. The following tasks were accomplished: an analysis of the functioning of the market at the present stage; recommendations are proposed for improving the development of the tourism market with the use of innovations. Methods of cognition, retrospective and documentary analysis, as well as synthesis, generalization, systematization were methods. In the article the assortment of innovative services is considered; proposed the organizational and economic mechanism of risk management in tourism and the main directions for improving management in tourism. Currently, the tourism industry in the regions is represented by a large number of small travel agencies. The fragmentation of the tourism industry creates information problems. In order to coordinate the activities of these firms, it is advisable to create a single center that performs information, coordination and dispatch functions. In addition, measures should be envisaged to eliminate the resulting damage on the basis of recovery technologies. At the same time, for effective management of business risks, effective management is most important, and for consumer risks different types of insurance.

Abstract
The solution of the problem of food security in the region plays an important role in providing the population with the necessary food. The article describes ways to achieve food security. Different opinions are presented on the causes of the problem of food security, in particular the spread of genetically modified organisms, as well as low incomes of the population, the volatility of food prices and insignificant reproduction opportunities. The analysis of production and consumption of various food products in the Russian Federation (RF) in recent years has been carried out. Dynamics of consumption of the main types of food in the Voronezh region is also presented. An analysis has been made of the production and consumption of various food products in the Russian Federation (RF) in recent years. Dynamics of consumption of the main types of food in the Voronezh region is also presented. A solution to the problem of food security with flour culinary products using non-traditional plant raw materials, also used as functional food products, was proposed. Examples are given of improving the quality of food products and increasing the content of dietary fiber and other useful nutrients, thanks to the use of secondary raw materials, bugs and processed products of plant origin. The food security of the region has only conditional territorial localization, since the economic relations that arise between the subjects of the food sector cover all subjects of the regional economy without exception. A special role in these relations in the conditions that have developed up to now is played by organizations related to the sphere of food production, as well as organizations that supply them with the most scarce and significant resources, i.e. organization of education, research and development. That is why, we believe that the main emphasis in the study of food security should be made on the specifics of the functioning of industrial organizations occupying a leading position in the food market and on their interaction with educational and research institutions.

Abstract
The process of reproduction of national wealth is accompanied by transaction costs, which have a number of features. The structure of these costs is heterogeneous. Due to the fact that the bulk of the costs directly associated with the provision of exchange between individuals. Size and structure of transaction costs has a significant impact on the dynamics of investment in the development of the national wealth and its movement in stages of the reproductive process. Transaction costs create an incentive system that determines the behavior of individuals in certain circumstances. Due to the fact that the objectives of economic agents are mixed, then some of them will be interested in minimizing transaction costs and other directly will tend to increase. The problem of transaction costs in the process of reproduction of national wealth are unexplored in current economic literature. In this regard, it is expected to determine and clarify the nature of these costs, their causes, the distinctive features and characteristics. Clarified that the basic forms of transaction costs of reproduction of the national wealth are: the costs of finding the required resources and estimation of their useful properties; the opportunity costs; the costs of Contracting and enforcement; the costs of economic realization of ownership of human capital. The study of characteristics and forms of transaction costs, as well as the specifics of their manifestation enables minimization. To this end, developed evaluation criteria for all forms of transaction costs, explored the contradictory nature of the impact of transaction costs on the reproduction of the national wealth, institutional arrangements and tools, the use of which will allow not only to minimize these costs, but under certain conditions to ensure their growth..

Abstract
The article deals with the organization management based on the strategy of social responsibility implementation that supplies the conditions for a company's competitiveness development. The theoretical statements by the leading foreign researchers about the key role of social factors in an organization success and the main conditions of competitiveness such as human resources, staff competences, customers' pleasure, an organization's reputation, organizational and managing capacity, etc. The author discusses the idea of the new aim of the management paradigm is "social business" development in the economy. Despite the fact that entrepreneurship is still based on getting the economical benefit, the competitive area, the methods and the relationship between the profit and the competitiveness have changed in the post-industrial era. The change of the consuming society structure and the complication of the competitive area make us look for other sources of competitiveness, such as investments into the human resources. Such an approach to competitiveness is more and more spread among the foreign and national companies and allows to include social aspects management into the development strategy of a company. It is stated that a socially responsible company includes social goals in the production process, thus ensuring a competitive advantage in business. An important conclusion of the research is that socially responsible organizations create better conditions for the territories’ development where they provide the society with a generally higher welfare level.

Abstract
The local food markets represent interaction of local producers and consumers of food production. This approach is the general, however, not losing the relevance and not exposed to serious substantial criticism. For several honeycombs years scientists show solidarity, marking out as basic elements of market conditions demand, the offer, the prices and the competition, and as the main subjects of market interaction – producers and consumers of goods, specific to the concrete market. At the same time the questions disclosing the nature of interaction, his form and also distinctive characteristics of subjects of interaction and the relations arising between them are debatable. Perspective form of interaction of subjects of the local market of meat production is the integration of producers and processors of raw materials aimed at providing production of the innovative production capable to find solvent demand even in the conditions of low consumer ability of the population today. Stabilization and development of the meat industry, increase in efficiency of his work in no small measure depend on his diversification, structural transformations by reforming and further improvement of the vertically integrated companies. Therefore the special relevance was acquired now by a problem of vertical integration and improvement of structure of the meat-processing enterprises by formation of the vertically integrated structures uniting all technological chain in a whole. Diversification allows to fix economic communications, to strengthen incentives for obtaining the most effective end result, to concentrate resources in the most effective directions of economic and technological technical policy, to solve separate problems of use of production and social infrastructure..

Abstract
The need to regulate environmental management activities of institutional entities arises when it affects the interests of third-party entities or threatened by the ongoing entity manufacturing practices its own resilience, to achieve the main goal. The complexity and diversity of the forms of socio-ecological and ecological-economic issues at different levels of the economic system leads to the development of many directions and views on the expansion of the management process of these levels (global, national, regional, local) and techniques from rigid-deklorative state before combination with the market. In this respect, the neoclassical economic theory actively generated new analytical ideas and concept that enables to respond adequately to emerging economic realities. So we can distinguish the following approaches to regulate environmental management activities: T. Malthus and D. Ricardo, revealing issues of social, ecological and economic implications of limited natural resources in the context of the law of diminishing effectiveness and the need to regulate environmental management activities. John. St. Mill and George proved to be ineffective in addressing environmental problems in the industrial economy of the type of the imperfection of the institutions of society, justifying the occurrence of crises protohistoric speculation nature's benefits. A. Pigou developed the theory of externalities, which revealed the need for state regulation of the environmental management activities of economic entities, harmonization of individual and social interests. Research I. Kula, F. Khan and P. Samuelson identified a pattern about the formation of the system of regulation nature-safety activities, not only within individual States but also on a global level. R. Crows have shown that the methods of direct state regulation of nature economic activity is not as good as it seems at first glance and so you should not underestimate the role and potential methods of market regulation problems. It is now generally accepted that environmental management activities of market actors only on the basis of the market mechanism of self-regulation is detrimental to the society and should be regulated.The need to regulate environmental management activities of institutional entities arises when it affects the interests of third-party entities or threatened by the ongoing entity manufacturing practices its own resilience, to achieve the main goal.

Abstract
The general conditions of formation of prices of products is obligatory accounting of all types of expenses. In the conditions of market relations, for each enterprise, the system of objective accounting of costs and management of costs necessary for production of products (services) becomes especially important. The system of management accounting, on the one hand, allows for the accounting of production costs, and on the other – to analyze costs and assess their impact on the final result of the enterprise and the adoption of appropriate management decisions. Unlike the full cost costing system, the cost accounting system known in economic theory is based on separate accounting of fixed and variable costs, which allows to take into account the impact of fixed costs on pricing and profits from the sale of final output. On the basis of application of the device of fuzzy sets the technique of determination of rational, from the point of view of the producer, the price of production (services) in the conditions of the available uncertainty of market researches and competitive advantages of the enterprise in the market of identical production is developed. In General, instrumental support of such approach to the determination of the product price is considered as a specialized information system to support the decision-making on the product price based on the results of market research. The market determined by this yield vector can be considered acceptable for the enterprise with a value of 0.55. At the same time, it may be accepted as unacceptable, but the level of clarity of assessment will be lower, namely 0.45. As you can see, the classification was quite blurred, which is a reflection of the fuzzy initial estimates of the proposed sales volumes for a certain price corridor.
