Abstract
An external recirculation loop was used as the method of increasing the concentration of dry soluble substances in the obtained extract. The objective of the research is to determine the value of the external recirculation index (KR), which provides the optimal conditions for the process carrying out. The results of the conducted research show the increase in the concentration of dry soluble substances in the extract if the external recirculation index increases. It is conditioned by the extension of the interaction between the processed raw mate-rial and the extract, as well as by the decrease in the surface tension of the extracting agent, which results in improving the conditions of its penetration into the pores of particles. Such an opposite property of recirculation as the decrease in mass transfer rate was also ob-served. It causes the significant rise of dry soluble substances losses while discharging extraction cake, which leads to the performance degradation. According to the analytical evaluation of the obtained results, the maximum process results are observed if KR = 1 (without recirculation) and KR = 2, the values of the optimality criterion are 5.02∙10-3 and 4.92∙10-3 % mass/W respectively. At the same time the operation of the apparatus with the recirculation loop at KR = 2 is characterized by 62%-increase in dry soluble substances concentration in the extract as compared to a pure extracting agent. The efficiency of recirculation at KR = 2 is proved by the saving of energy con-sumed on the evaporation of the extract obtained. The energy costs calculation for the production of 60l of 12 % mass dry soluble sub-stances concentration extract showed that if the initial dry soluble substances concentration is raised to 6 % mass (KR = 2), the amount of consumed saturated vapor is 104.1 kg less, which is 281685 kJ if the vapor specific enthalpy is 2706.29 kJ/kg.

Abstract
One of the most promising oil crops in the Russian Federation is saffron. Camelina seeds contain from 26 to 46% oil, which is different from other oils rich in cruciferous gondoinic, linolenic and linoleic acids, and relatively low erucic acid, has a high content of the biologically active substances (sterols, carotenes and carotenoids, chlorophylls and tocopherols). The main task in the processing of oilseeds is the maximum extraction of oil with a high quality of the products obtained: unrefined oil, cake and meal. In conventional technology of oil, the raw material is subjected to repeated heating significantly. Proposed the following processing flow chart: camelina seeds were subjected to moisture-heat treatment beforehand in an extruder, and then hot-pressed to a screw press a single action, so that the oil content of the cake after pressing was 17-19%. When using an extrusion process is suppressed anti-nutritional properties contained in the seeds of camelina. Found that the oil obtained after the preliminary preparation of the extrusion as compared with the oil produced by traditional technology, comprises more tocopherols, phospholipids less chlorophyll, free fatty acids and peroxides. Thus, it has a longer shelf life, has good fluidity, easily refined.

Abstract
To the salting process of fish many studies are devoted, both in experimental and in theoretical terms. Study of features of fish salting in historical terms can be divided into 3 groups. One group of researchers believes that osmotic pressure has a major influence during the salting process. Another group attributed this process to the influence of molecular diffusion. The third group considers that during this process takes place both osmosis and diffusion. Determination of the main characteristics (salinity, diffusion coefficients, time of salting, etc.) is a very time-consuming task. This leads to the idea of searching for innovative research methods. Current state of science, in addition to theoretical solutions points to the possibility to determine the basic characteristics of salting and applying methods associated with the interaction of ultrasound and electromagnetic radiation with matter. In our studies, we have been producing laser beam scanning of salt solution and fish meat thickness. Scattered radiation is determined by the salt concentration, diffusion coefficients, the size of the diffusing particles. This method is called a photon correlation spectroscopy. It has been applied in our work. The dependence of the scattered light intensity on the concentration of sodium chloride solution (brine) has been investigated. According to diffusion coefficient a diffusion in solution to herring skin a conclusion was made that salt solution obtains fractal structure and its size was determined. Also we determined diffusion coefficients depending on the temperature in the layers. The layers are brine-leather, leather, and herring meat thickness. The process of diffusion-osmotic equilibrium revealed at temperatures of 10-12 ° C. Suggested the possibility of higher quality of fish salting at low temperatures. On the basis of the selfsimilar solution of the differential diffusion equation, a formula for calculating time salting fish was obtained

Abstract
The theoretical presuppositions for the possibility of generalizing and similarity founding in dehydration and wet materials heating processes are studieded in this article. It is offered to carry out the given processes generalization by using dimensionless numbers of similarity. At the detailed analyzing of regularities of heat treatment processes of fish in different modes a significant amount of experienced material was successfully generalized on the basis of dimensionless simplex (similarity numbers). Using the dimensionless simplex allowed to detect a number of simple mathematical models for the studied phenomena. The generalized kinetic models of fish dehydration, the generalized dynamic models (changing moisture diffusion coefficients), the generalized kinetic models of fish heating (the temperature field changing in the products thickness, average volume and center) were founded. These generalized mathematical models showed also relationship of dehydration and heating at the processes of fish semi-hot, hot smoking (drying) and frying. The relationship of the results from the physical nature of the dehydration process, including a change in the binding energy of the moisture with the material to the extent of the process and the shrinkage impact on the rate of the product moisture removal is given in the article. The factors influencing the internal structure and properties of the raw material changing and retarding the dehydration processes are described there. There was a heating rate dependence of fish products on the chemical composition the geometric dimensions of the object of heating and on the coolant regime parameters. A unique opportunity is opened by using the generalized models, combined with empirically derived equations and the technique of engineering calculation of these processes, to design a rational modes of heat treatment of raw materials and to optimize the performance of thermal equipment.

Abstract
Grain-crops are justly considered to be the staple food in Russia as well as all over the world. The specific feature is that postharvest processing of the grain and, above all, drying is an essential stage of providing products of high quality in the sufficient amount. The changes of the technological parameters of the drying process which take place over time, have a significant practical value in terms of monitoring the process and defining the modes providing the quality of the product as well as calculating energy demands necessary to carry out this process. Hereof, the quality of the product received is defined by minimum crack formation of rice grain after the process. The aim of the work is to get a mathematical model of hygrothermal mechanics of rice drying. On the basis of A.V. Lykov’s system of differential equations which describe the changes in moisture content, temperature and pressure, transition to the system of ordinary differential equations was offered which is based on drawing up balance of mass and heat during the process of drying. This approach does not consider the properties of moisture content and temperature within the material but takes into account their mean value. Using a simplified model of hygrothermal mechanics of rice drying that we have got enabled us to reproduce the process of drying in the conditions of minimum crack formation within the studied range (the temperature of the drying agent from 50 to 70 °C, speed from 2.3 to 2.8 м/sеk). The dependences we have got enable us to predict the quality of rice grain during drying.

Abstract
The article is devoted to the mathematical modeling of the kinetics of ethyl benzene dehydrogenation in a two-stage adiabatic reactor with a catalytic bed functioning on continuous technology. The analysis of chemical reactions taking place parallel to the main reaction of styrene formation has been carried out on the basis of which a number of assumptions were made proceeding from which a kinetic scheme describing the mechanism of the chemical reactions during the dehydrogenation process was developed. A mathematical model of the dehydrogenation process, describing the dynamics of chemical reactions taking place in each of the two stages of the reactor block at a constant temperature is developed. The estimation of the rate constants of direct and reverse reactions of each component, formation and exhaustion of the reacted mixture was made. The dynamics of the starting material concentration variations (ethyl benzene batch) was obtained as well as styrene formation dynamics and all byproducts of dehydrogenation (benzene, toluene, ethylene, carbon, hydrogen, ect.). The calculated the variations of the component composition of the reaction mixture during its passage through the first and second stages of the reactor showed that the proposed mathematical description adequately reproduces the kinetics of the process under investigation. This demonstrates the advantage of the developed model, as well as loyalty to the values found for the rate constants of reactions, which enable the use of models for calculating the kinetics of ethyl benzene dehydrogenation under nonisothermal mode in order to determine the optimal temperature trajectory of the reactor operation. In the future, it will reduce energy and resource consumption, increase the volume of produced styrene and improve the economic indexes of the process.

Abstract
in long audio recording is practically not studied. To recognize the audio signals and their counting were analyzed and used mathematical methods such as correlation analysis, fast Fourier transform, fuzzy logic. Looking at each method in turn, were selected for the parameters gives the best recognition results when using either method. Correlation analysis allows to draw conclusions about the number of cough moments for the selected standard. Fast Fourier transform allowed to allocate these frequency ranges, which are the only cough and do not get the noise was experimentally identified 6 of these ranges. The use of fuzzy logic has improved the analysis of sound recordings and allowed to make the choice of the cough moments with more certainty, but certainty of results to achieve and failed. Used fuzzy logic, which allows to expand the boundaries of recognition, allowing graded result in coughing may cough and noise. When analyzing the data obtained for each of the mathematical method, came to the conclusion that individually cannot be used. To achieve this goal it is necessary to compile a set of mathematical rules of inference that allow to recognize the sound signals with higher accuracy. Having considered the spectrogram of a sound clip, select the zone in which it is necessary to conduct an analysis to identify the similarity of sound recordings. The zones of cough have distinct values for each of the coordinates of the spectrogram. This allowed later when synthesizing inference rules use the exact values for the parameters of these rules. Under the resulting set of rules modified the developed software. Tested and received results.

Abstract
In this paper we consider the problem of approximating the experimental values of the coefficient of attenuation of ultrasonic oscillations and the mass distribution of the fat globules in the milk and milk products. The analysis of experimental data in terms of the choice of the method of approximation was done. A approximating dependence is based on the solution of Pearson differential equations. The advantages of the proposed method for the type of approximation of the experimental data obtained. An algorithm for constructing a mathematical model describing the relaxation spectrum and mass distribution of the fat globules in the milk and milk products was implemented. As a result, a family of Pearson approximation curves of the experimental data shows the ability to qualitatively correctly describe the change in the distribution of the fat phase in the process of homogenization. It estimates the error of approximating dependence, which amounted to 18 %. It is shown that during of the process of homogenization of dairy products changes shape of the curve describing the distribution of the fat globules, in view of the fact that there is a local extremum, caused by the presence of the non-homogenized fat globules. The accuracy of the selected mathematical model is significantly reduced. At the same time, it loses its physical meaning and its parameters. To address the identified deviations in the proposed mass distribution of fat globules as a function with two modes. It is proved that the complexity of the model is not only doubles the number of its parameters, but also complicates the interpretation of measurement results in a control system, and makes it difficult to analyze the obtained parameters of approximation by decision-maker. As a result of approximation of experimental data suggested to use statistical moments of the distribution for problem decision.

Abstract
In connection with the transition of the educational system to a competence-oriented approach, the problem of learning outcomes assessment and creating an individual learning trajectory of a student has become relevant. Its solution requires the application of modern information technologies. The third generation of Federal state educational standards of higher professional education (FSES HPE) defines the requirements for the results of Mastering the basic educational programs (BEP). According to FSES HPE up to 50% of subjects have a variable character, i.e. depend on the choice of a student. It significantly influences on the results of developing various competencies. The problem of forming student’s learning trajectory is analyzed in general and the choice of an individual direction was studied in details. Various methods, models and algorithms of the student’s individual learning trajectory formation were described. The analysis of the model of educational process organization in terms of individual approach makes it possible to develop a decision support system (DSS). DSS is a set of interrelated programs and data used for analysis of situation, development of alternative solutions and selection of the most acceptable alternative. DSSs are often used when building individual learning path, because this task can be considered as a discrete multi-criteria problem, creating a significant burden on the decision maker. A new method of controlling the learning trajectory has been developed. The article discusses problem statement and solution of determining student’s optimal individual educational trajectory as a dynamic model of learning trajectory control, which uses score assessment to construct a sequence of studied subjects. A new model of management learning trajectory is based on dynamic models for tracking the reference trajectory. The task can be converted to an equivalent model of linear programming, for which a reliable solution methods are developed. To solve large-scale problems, you can use the control method with the predictable model.

Abstract
The conducted researches allowed to establish that intensive disintegration of a muscular glycogen leads to sharp decrease in size рН muscular tissue in the sour party that in turn affects a chemical composition and physic-colloidal structure of proteins therefore: resistance of meat of fish to action of putrefactive microorganisms increases; solubility of muscle proteins, level of their hydration which is water connecting abilities decreases; there is a swelling of collagen of connecting fabric; activity of the cathepsin (an optimum рН 5,3) causing hydrolysis of proteins at later stages of an autolysis increases; the bicarbonate system of muscular tissue with release of carbon dioxide collapses; predecessors of taste and aroma of meat are formed; process of oxidation of lipids becomes more active. As a result of accumulation dairy, phosphoric and other acids in meat of fish concentration of hydrogen ions of that decrease рН is result increases. Sharply shown sour environment and availability of inorganic phosphorus is considered the reason of disintegration of an actin-myosin complex on actin and a myosin which begins after 8 hours of storage, i.e. there comes the period of relaxation of muscle fibers and the period of permission of an numbness, and then the last stage of maturing of meat – deep autolysis. Thus, on the basis of classical ideas of biochemical changes of meat of land animals and summarizing the obtained data on posthumous changes in muscular tissue of fishes, it is possible to draw a conclusion that they have similar nature of regularity in comparison with muscular tissue of land animals, but their main difference is higher speed of course of autolytic transformations. It in turn leads to faster change of FTS of meat of fishes who are the defining indicators when developing assortment groups of products taking into account stages of an autolysis in meat.

Abstract
Wheat germs flour is protein-rich with a full complex of amino acids. Comparison of a chemical composition of flour from wheaten germs with different nuts types shows that they don't concede on a nutrition value, and in the vitamins content of both some macro and microcells surpass nuts several times. Thus, considering preference of consumers of natural products and the maximum exception of compounding of synthetic taste-aroma maker, a problem of formation of nut aroma in the final product made with nuts replacement takes place. In our work we studied influences of heat treatment on aroma formation of wheat germs flour with application of piezo-sorption of "an electronic nose". Various content of easily volatile organic compounds in an equilibrium gas phase over tests depending on conditions of heat treatment is established: most of them in aroma of test 2, the smallest – in tests 1 and 4. On intensity of aroma or the contents of separate classes of easily volatile compounds the test differs from test standard. It is found out on responses of separate sensors that the equilibrium gas phase over samples contains hydrophilic connections and water, the content of nitrogen-containing and specific (aromatic) connections, esters is essential. On intensity of aroma or the maintenance of separate classes of easily volatile compounds the tests differ from test standard. Thus for the tests 3, 4, 5 the content of high-polarity volatile compounds increases (including ketones, alcohols), the content of esters, acids decreases. On a ratio of separate classes of connections in an equilibrium gas phase noticeable influence of time of heat treatment on redistribution of connections of RGF for flour of germs of wheat is determined. Thus, the heat treatment duration influences wheat germs flour aroma. From the received results of "visual prints" of wheat germs flour of various degree of roasting, optimum time of heat treatment at which "nut" aroma appears ranges from 6,5 to 10,5 min. at a temperature of 150 °C is determined.

Abstract
The article presents the results of studying the effect of using table salt, apple juice and citric acid on quality parameters of aerated dough and bread prepared by mechanical leavening. The wholegrain flour from chickpea seeds has been used to prepare dough. The amount of salt is in the range from 1 to 3 %, apple juice from 5 to 25%, citric acid 0.05 to 0.2 % over the weight of the flour. The working mechanism of recipe components on the process of foaming while kneading of the semi-finished products of chickpea flour has been identified. The increase of their amount leads to increase of active acidity of the test and brings the protein pH to isoelectric point. Thus increasing the foaming capacity of the albuminous substances while kneading the semis. It has been founded that the maximum foaming capacity of the semis is achieved at pH 5.5. At the same time a decrease in the bulk density of the dough and the increase in specific volume of the baked product. In this case, the samples are characterized by lower bulk density (0.32 g / cm3 ), and maximum specific volume of finished product (365 cm3 / 100 g). The reasonable amount of components in the bread recipe: table salt 1.5 %, apple juice 5.0 %, citric acid 0.1 % over weight of flour has been recommended. The data obtained form the basis for the development of technology of aerated bread "Atreus" with higher nutritional and biological value. The degree of satisfaction of adult daily need of 100 g of the product is, %: protein 17, dietary fiber 39, magnesium 21, phosphorus 28, iron 30, potassium, thiamine and riboflavin 18. The product is recommended for mass consumption in order to enrich dietary intake with protein, dietary fiber. minerals and vitamins.

Abstract
An important aim during smokeless tobacco product (snus) storage is keeping its quantitative and qualitative properties. Another significant factor is its biological safety due to its oral way of consumption. The main factors affecting quality during storage are: temperature, relative humidity, air composition, ventilation rate, surrounding products and package. Snus consumption is growing, but till present it was slightly spread in Russia and as a result little studied, thus studying process of its storage is an actual question. The aims of the research were: studying terms and methods of storage that provide constant product’s quality. Samples with different composition were taken for carrying research. Quality evaluation was carried according to standard for tobacco branch methods and to new methods developed in the laboratory of technologies for manufacturing tobacco products. Products were stored at lowered and room temperatures. It is discovered that snus with herbs added can be stored at room temperature and humidity not more than three months. Snus with coffee added can be stored not more than four months without changing its taste. Adding honey to this product slightly decreases its score by sensory evaluation, but remains it possible for consumption. Sensory testing score after storage at lowered temperature has remained unchanged. Optimal terms of storage were found. For room temperature they are: temperature 17-25 °C, relative air humidity 65 – 75 %, for lowered temperature – 5 °C and relative air humidity 50 -60 %. It was discovered that composition of snus and environmental parameters affect its storage duration.

Abstract
The technology of fish protein isolate from the low-cost raw material – the polar cod meat – was developed. The rationality of using partial alkaline-acid hydrolysis of minced fish for making fish protein isolate from the polar cod meat increasing the full-grade highly functional protein yield was proved. The most significant technological parameters influencing the physical and chemical characteristics of isolate were obtained; they are the parameters of washing and hydrolysis processes. The experiments of determination of the dependency of shelf life of the frozen raw material on physical and chemical characteristics of the raw material were carried out. The optimal quantity of washing cycles depending on the storage time was determined, it is 4 for the polar cod stored less than 4 month, and 6 for the polar cod stored more than 4 months. The dependency of temperature and pH of suspension changes during hydrolysis on the most significant quality characteristics (protein content, isolate yield by minced fish, isolate soluability)was obtained. The optimal values of these factors are: the temperature of 98 ˚С, pH of 11.75. The technology of manufacturing cholesterol-free mayonnaise choosing the fish protein isolate as an emulsifier was developed. The high emulsifying ability of fish protein isolate in fine emulsion “oil in water” was proved: increasing the content of isolate by 0.6 % the emulsifying ability increases by 1.85 %. The organ, oleptic microbiological, physical and chemical analyses of the mayonnaise were carried out, the recommended shelf life (30 days at the temperature from 3 to 5 ˚С) was found. The fish protein isolate was also used for meat and fish frankfurters.

Abstract
In the article discussed the mathematical formulation and numerical algorithm for solving the problem of calculating the temperature field in the process vulcanizing of the product, whose the thermal characteristics are depended on the temperature. As a mathematical model considered the system of differential equations of heat conduction, taking into account the change in the coefficients of thermal conductivity and heat density in multilayer product of the temperature. The system of equations is solved for a given initial distribution of temperature and for a given (time-dependent) temperatures on the border of the product to the press-mold and to the diaphragm. On the border of the contacts of adjacent layers are given the condition of continuity of temperature and heat flux. Change of the thermal conductivity from the time is approximated by linear functions. The activation energy of the vulcanization process is determined on the basis of experimental data obtained in the control test samples using a reometer. Considering the function representing the corresponding integrals of the thermal conductivity, the original system of differential equations is transformed to an equivalent system of differential equations convenient for constructing numerical algorithms for solving the problem. The resulting system of partial differential equations derived using the method of finite-difference approximation is replaced by a system of algebraic equations. Solution of the system of algebraic equations is carried out under the scheme explicit difference approximation. In the article calculated the temperature field for the tire at given initial and boundary conditions. Stability and accuracy of the numerical algorithm for solving the problem is demonstrated by the calculations performed with different sampling step along the time and space coordinates. Assessment of the degree of completion of the process is carried out by calculated equivalent time for temperature values, accepted as equivalent. The developed algorithm is an important part of the algorithm for solving the problem of determining the optimal mode of curing, providing the required quality products at the lowest cost, which is very important in conditions of continuous growth in energy prices.

Abstract
In this article we discuss the features of detection of microconcentration toxicants (ammonia, butanol-2, toluene) in natural waters with different salt concentration using the piezoelectric crystal quartz microbalance on gas analyzer “MAG-8” with injection input of sample. The samples of sea water were classified into groups by values of electro conductivity, total mineralization and hardness. Piezoelectric microbalance of equilibrium gas phase over sea water samples carried out in eight-sensors chamber (electrodes modifiers – multilayer carbon nanotubes, propolis (bees wax), polyethylene glycol 2000, polyethylene glycol sebacate, dinonylphthalate, three octylphosphate, methyl orange with polystyrene, Triton X-100) in static condition. The electrodes modifiers were chosen by criteria of minimal sensitivity to water vapors and different (crossing) sensitivity to vapors of anthropogenic pollutants. The primary analytical information of sensors array is integral characteristic of gases mixtures over water sample – “visual print” of sensors. It has been shown the dependence of “visual print” square of sensors array responses on concentration salts and electro conductivity of sea water samples. Using the methods of additives it is established the behavior of influence the microconcentarion of ammonia, butanol-2, toluene on summary indicator of sensor array. The possibility of toxicant identification in model solutions using selected identification parameters Aij is demonstrated. It has been shown the classification of sea water samples with toxicants additives by parameters of sorbtion efficiency and optimization of piezosensors array for analysis of natural water using the processing of sensors output data by principal component analysis. The most significant to separation of water samples with toxicant there are responses of sensors with films from polyethylene glycol sebacate, dinonylphthalate, three octylphosphate, and the electro conductivity of natural water is less significant.

Abstract
Anthocyanins red pigments that give color a wide range of fruits, berries and flowers. In the food industry it is widely known as a dye a food additive E163. To extract from natural vegetable raw materials traditionally used ethanol or acidified water, but in same technologies it’s unacceptable. In order to expand the use of anthocyanins as colorants and antioxidants were explored extracting pigments alcohols with different structures of the carbon skeleton, and the position and number of hydroxyl groups. For the isolation anthocyanins raw materials were extracted sequentially twice with t = 60 C for 1.5 hours. The evaluation was performed using extracts of classical spectrophotometric methods and modern express chromaticity. Color black currant extracts depends on the length of the carbon skeleton and position of the hydroxyl group, with the alcohols of normal structure have higher alcohols compared to the isomeric structure of the optical density and index of the red color component. This is due to the different ability to form hydrogen bonds when allocating anthocyanins and other intermolecular interactions. During storage blackcurrant extracts are significant structural changes recoverable pigments, which leads to a significant change in color. In this variation, the stronger the higher the length of the carbon skeleton and branched molecules extractant. Extraction polyols (ethyleneglycol, glycerol) are less effective than the corresponding monohydric alcohols. However these extracts saved significantly higher because of their reducing ability at interacting with polyphenolic compounds.

Abstract
Currently to the quality of ethyl alcohol increased requirements. The task of this research was to examine the effects of alcohol depuration and development of new methods of calculation based on the model of theoretical plates. The paper examines the work depuration column at different modes. Were composed material balance equation and it is calculated concentration distribution of ethanol on the plates of the column. Further we obtained equations for estimating the effects of ethanol purification from the accompanying impurities. The carries out calculations have shown that when depuration column working with water selection method observed the significant decrease in the concentration of ethanol on her plates. As a result, increases the coefficient evaporation of impurities, which considerably improved it concentration. But it fortress of epurate reduced, which may degrade the performance of the distillation column and result in a loss with the bottoms liquid. It was therefore reviewed variant with the installation of the stripping part on depuration column, thereby increasing the concentration of ethanol in epurate and reduced the content in it of organic acids and other tail impurities that are discharged with liquid from her cube. Having recorded material balance equation for the stripping part, it was determined that are no losses of alcohol with cube liquid are. With some assumptions, from the equations of material balance are obtained the equations allowing estimating proportion of tail impurities withdrawn with cube liquid. The calculations have shown that more than half of the tail impurities incoming to the depuration column removed from her cube.

Abstract
The sauces on the basis of vegetable oils and mayonnaise which are traditionally considered tasty, but not really useful at enrichment by functional additives can be used not only for flavoring decoration of various dishes and salads, but also for increase of their nutrition value. Dzhus received by production of salty granular caviar of a humpback salmon represents a full-fledged complex of the major food factors that can serve as motivation for its use when developing new food, including in the form of a proteinaceous and mineral additive for its additional introduction to compoundings of sauces. In view of existence of a fish smell of a caviar dzhus, it is possible to use it as natural fragrance by production of the wide range of fish products, including emulsion. For an assessment of quality of production, fast and simple the organoleptic (touch) method is very convenient. Various content of easily volatile organic compounds in an equilibrium gas phase over tests is established. Samples of a caviar dzhus among themselves and sauces with its addition differ. Distinctions are defined by amount of the brought ingredient. The intensity of a smell of tests determined by the content of easily volatile compounds on which the massif of sensors is adjusted differs. Sauces with an additive of a caviar dzhus have the greatest intensity of a smell in accordance with GOST at its small contents. In a figure form of "a visual print" of the maximum responses of all sensors in the massif distinctions in a chemical composition of an equilibrium gas phase over tests are established.

Abstract
In the conduct of many processes, including during operation of the drying equipment is well proven two-stage purification scheme of the coolant, including units for dry and wet cleaning emissions. This article was reviewed the system of purification of air of the shop of drying specializing on production of food powders on the example of powder of soluble tea. Detected locations the emission of dust in shop of drying, by production of soluble food powders, parameters of the fulfilled dryer heat carrier are determined, physical and structural and mechanical properties of the received product are analyzed, and also overall performance of the means of purification of air existing at the enterprise is defined. It is revealed that when drying this powder emissions contain a big share of fine fraction of the dust possessing high hygroscopicity and big adhesive ability and use of the hose filter as the second step of cleaning is inadmissible. The average value of catching the cyclone was in the range of 72-76 %. This is due to the fact that this dust is characterized by the presence of a large percentage of the fine fraction, which is poorly captured by the centrifugal dry cleaning apparatus. After analyzing the effectiveness of existing treatment systems, it is possible to draw a conclusion about inexpediency of its use in the enterprise when the dust dispersed composition of this and the need to develop other, better and more effective option. Used conical cyclone is not very effective device for cleaning of coolant from fine dust, so its use is possible only as the first stage of two-stage air purification. From the obtained results it follows that the existing air cleaning system did not provide the required efficiency. To ensure the required level of purification of exhaust air should take into account the special properties of the dusts of a particular production. As the second stage in this case, with regard to the specific characteristics of this type of dust, it is advisable to use wet types of cleaning. It was suggested use for cleaning of the heat carrier of the wet device of centrifugal and inertial action is offered. The presented generalized characteristics of dust can serve as the material allowing to estimate danger degree in the sanitary and hygienic relation of this or that technological process and are basic data for calculation of an efficiency of the operating clearing equipment and design new.

Abstract
Currently, much attention is paid to development, allowing use of waste and by-products formed during certain manufacturing processes. This allows you to either reduce or completely eliminate the use of valuable and expensive raw materials. The use of this raw material in the production of synthetic rubber will not only reduce the cost of coagulation and acidifying agents, but also to improve the environmental situation. Featured in some cases effective coalescing agents based on polymeric quaternary ammonium salts (PCHSA) have a high coagulating power, and hence low consumption of the allocation of the rubber latex (3-5 kg0t-1 rubber). Scarcity and high cost of these drugs leads to higher prices resulting rubber. Furthermore it is known that the application requires keeping PCHSA sufficiently precise dosage administered substances by the action of a latex, owing to the high capacity of the antiseptic may lead to discharge into natural waters polluted waters. However, using as the coagulating agent departing sugar production molasses solves a number of problematic steps in the production of synthetic rubber. First, a well-studied effective coagulation effect of different nitrogen derivatives relating to cationic surfactants. In freshly prepared solutions of molasses contained about 9 wt%, and this value increases significantly during enzymatic fermentation. Secondly, highly acidic environment of aqueous solutions of molasses after storage can allow their use in addition to or instead of the sulfuric acid used in large amounts (up to 15 kg m-1 rubber) technology selection tests carried found that vulcanizates derived from rubber samples isolated molasses, consistent with the requirements and were similar to control samples prepared from the latex using sodium chloride.

Abstract
Retained on a membrane solute in reverse osmosis separation of biological fluids at the surface of the membrane gradually accumulates and forms a boundary layer, where its concentration is higher than in the bulk. Increased concentration of solute in the solution at the membrane surface causes a diffusive flow of solids from the membrane surface into the bulk solution. After some time in the system t is a stationary state. A convective flow of solute to the membrane surface will be balanced by the sum of the fluxes of solute through the membrane and from the membrane surface into the bulk solution, i.e. in the case of concentration polarization is formed an edge of the diffusion layer. It is established that the concentration-polarization in reverse osmosis separation of the aqueous biological fluids biochemical production is influenced by the flow rate of solvent and the mass transfer coefficient. Experimental study allowed to characterize that by using the process of reverse osmosis can effectively divided, clear, and contaravati industrial solutions biochemical industries. Data at a rate of detention allow to evaluate the influence of concentration polarization on the efficiency of the reverse osmosis separation of industrial solutions. As a result of systematization and evaluation of experimental data and dependencies at a rate of detention found that with increasing the concentration, the rate of detention of solutes decreases. Based on the analysis and modification of the proposed equation for theoretical calculation of detention. Theoretical description of the coefficient detention accurately adequately calculated the modified equation N. V. Churaev, B. V. Deryaguin and V. M. Starov. The numerical values of the empirical coefficients, to calculate and predict the odds of arrest for a similar membrane separation processes industrial solutions. Values obtained correlation coefficients. The correlation coefficients specify that the rate of detention has a strong inverse dependence on the concentration of the dissolved substance, which confirms the influence of concentration polarization on the coefficient detention membranes.

Abstract
Evaluating the effectiveness of integration formations requires an integrated approach that combines the use of both quantitative and qualitative indicators. Existing methods for analyzing the effectiveness of economic processes can not be formally applied to the problem of assessing the effectiveness of the implementation of the integration units for many reasons. Application of statistical analysis of historical data or case law causes difficulties due to the uniqueness of integration activities and the impossibility of duplicating administrative decisions due to the specifics of the internal environment of organizations, market instability, the effect of different environmental factors that necessitated the economic and mathematical modeling, expert assessments of the effectiveness of the integration units (EIF) with using linguistic variables and methods of the theory of fuzzy numbers. Selected mathematical tools used in the proposed model the theory of fuzzy sets, which makes it possible to analyze the qualitative variables, manipulate the input data and fuzzy linguistic criteria, as well as to model complex systems and to compare them with each other. Economic-mathematical model provides an assessment of EIF in two stages. At first defined the generalized evaluation of each of the nine blocks that characterize the contribution of block EIF, the second integral evaluation performed EIF. Conclusion on the integrated assessment of EIF can be obtained by analyzing the values of integrated assessments, reflecting the impact of the block. Recent consider, in turn, that comprehensive evaluations were obtained from the analysis values of the indicators. It is necessary to ensure the fulfillment of the requirement to increase the value of each evaluation index, or was coupled with an increase in value of EIF. This requirement is satisfied when the transition to the linguistic values. The algorithms implementing the steps vary the transitional linguistic variables qualitative indicators and values of linguistic variables estimated EIF, the rest of the algorithms are identical. Presentation of the economic-mathematical model to derive a comprehensive qualitative evaluation of the effectiveness of integration formations. The developed model is aimed at increasing the representation of management decisions and risk reduction integration formations based on industry characteristics meat industry.

The innovative activity is the main direction of the guarantee of the competitiveness today. However, the production of the new products and introduction of the new production technologies are not the only solution. It is important to ensure the current management system of enterprises to the new economic conditions to achieve positive results of the innovative activity. The management innovations are the instrument of the improving the management systems effectiveness of the domestic enterprises. The introduction and the implementation of the management innovations need to begin the process of innovative development. The author picks out the distinctive features of the management innovations on the basis of the practical experience. These are: the low level of study of the problem of the non-technological forms of the innovation, the low cost of development and implementation in comparison with the cost of product and technological forms of innovation, the lack of the ability to objectively assess the effect of the introduction and implementation, the dependence on the qualities and abilities of the manager, the ability to obtain the effect in a short time. These features can "help" the dissemination of the management innovations among the domestic companies, and "slow down" the process. So, the possibility of obtaining the positive effect in a short time and the low cost will contribute to the rapid diffusion of the non-technological forms of innovation in the management system of the enterprises, even in the crisis. The lack of sufficient knowledge about the management innovations and their dependence on the qualities and abilities of the manager are effect the implementation process negatively.
