Currently, the application of advanced technologies in sugar factories is relevant. These technologies are based on the use of a combination of physical and energy effects on the feedstock and provide a reduction in sucrose losses at the stage of diffusion juice obtaining. A method of press-diffusion production of juice from sugar beet which allows to increase the yield of sucrose from beet chips and to reduce losses at the stage of diffusion juice obtaining and production costs is suggested by us. The press-diffusion method of extracting juice from sugar beet with the methods of mathematical planning and statistical processing of the experimental results was studied in the work. Regression equations and suboptimal parameters providing the maximum yield of beet juice with minimum energy consumption for its implementation were received in experimental plants under the influence of technological parameters, which were the pressure applied to the beet mass at the pressing stage, the temperature at the diffusion stage, and the pretreatment temperature of beet chips before pressing and the frequency of ultrasonic vibrations of the emitter in the diffusion installation. These operating parameters were the following: pressing pressure 0.27–0.33 MPa, pretreatment temperature of beet chips 334.2–337.3 K, diffusion temperature 342.5–345.0 K and frequency of ultrasonic radiation 21.25–23.36 kHz. The engineering nomograms presented make it possible to determine the value of the specific energy consumption and the value of the liquid phase output from the technological parameters of the press-diffusion method for producing beet juice in a quick and qualitative way.
Experimental studies of the kinetics of the process of drying triticale grain during counter-current-direct blowing of the grain layer were carried out. In the experimental installation, a programmed change in the direction of the drying agent flow through the grain layer was carried out and the actual conditions of the drying agent supply through the supply and discharge boxes of the shaft grain dryer were emitted. Analysis of drying curves and drying rate of triticale grain showed the presence of only a period of decreasing drying rate, in which the intensity of moisture diffusion is significantly less than the intensity of moisture exchange. The organization of the experiment made it possible to fully adapt it to industrial mine grain dryers, in which the drying process is carried out in a continuous mode. Based on the results of the study, an empirical model of the drying process is proposed in the form of an exponential function, which establishes a unique functional relationship between the current moisture of the grain and the main parameters of the process: temperature, speed, moisture content of the drying agent and the thickness of the blown layer. Taking into ac-count the requirements to the process modes of grain drying, the triticale analyzes the ratio between the grain temperature and its humidity at various values of the mode parameters, which is proposed to be used as a restriction on the drying temperature mode.

Currently, there is a trend in decreasing of the number of pollinators, which is already a matter of food security. Bumblebees Bombus terrestris L. are economically important pollinators of vegetables and other agricultural crops. Recently, it has been suggested that the synergistic effect of pesticides and diseases that affect pollinators contributes to a sharp decline in the number of pollinators. In this work, we investigated the effect of new biodegradable fungicides on eukaryotic microorganisms Penicillium commune and Rhodotorula mucilaginosa isolated from the gut of Bombus terrestris L. larvae. It was shown that the new fungicides studied can inhibit the growth of both mycelial eukaryotic microorganisms and yeast eukaryotic microorganisms. Among the studied substances, the most effective was fungicide 2. The studied substances are selectively toxic only for eukaryotic microorganisms and do not have a toxic effect on animals, in particular insects, and can be used to treat insect pollinator infections caused by fungal microorganisms. It was noted that the new fungicides are more toxic to yeast than to mycelial fungi.
A modern progressive direction in the development of confectionery production is the creation of new resource-saving technologies and the development of flour confectionery products with a reduced energy value based on the use of various types of non-traditional and local raw materials. The application of oilseed cake in the food industry makes it possible to enrich products chemical composition with proteins, lipids, dietary fiber, vitamins and minerals. The use of amaranth oil cake as a dry component allows the biological value increase, as it is characterized by a high content of easily digestible protein (18-20%) containing all essential amino acids in sufficient quantities. Recently, special attention has been paid to the introduction of animal fats to the food industry. Bone fat occupies a special place among them. It is produced from bones, regardless of the type of meat from which they were obtained. The application of bone fat allows to enrich foods with polyunsaturated fatty acids, as well as improve the ?-3 / ?-6 ratio of fatty acids in the diet. Taking into account the traditional technology, as well as the properties of amaranth cake and bone fat, the recipe for "Mayachok" gingerbread was developed to adjust chemical and fatty acid composition. The recipe for custard gingerbread with the addition of 15% amaranth oil cake and 11% bone fat to the flour mass in the dough improves organoleptic and physicochemical indicators; to increase their biological value (by 24.5%); to obtain products with the most balanced amino acid composition (amino acid rate for lysine is 44.5%); to balance the ?-3 / ?-6 ratio of fatty acids; to increase the calcium content in products and to normalize its ratio with magnesium and phosphorus - Ca: Mg: P - 1: 0.65: 1.65. The components added improve the structural and mechanical properties of the choux pastry, such as plasticity, elasticity, absorptivity.
The increase in the number of cases of allergic reactions and celiac disease is an important problem. The solution to this problem is the search and development of relevant and effective ways to eliminate gluten. Specific amino acid sequences glutamine and proline determine the resistance to protease hydrolysis of the structural domains of gluten fractions. The analysis of the literature data showed that an alternative to the gluten-free diet is the use of biotechnological methods for modifying ingredients containing gluten. Such methods include the use of leavens on the base of lactic acid bacteria or enzyme preparations containing peptidases specific to gluten biocatalysis. In addition, the pretreatment of raw materials by extrusion cooking contributes to an increase in the degree of gluten hydrolysis. The effect of the thermoplastic extrusion and various enzyme systems containing proteases, amylolytic, cellulolytic and hemicellulolytic enzymes on the changes in the molecular weights of wheat protein fractions was studied. It was found that extrusion as a factor of protein modification significantly affects the proteolysis of wheat proteins using enzyme systems of different substrate specificity. The most effective hydrolysis was shown by the use of a complex enzyme preparation Amyloprotoorizin. including The effect was also noted after bioconversion of non-extruded wheat. An algorithm for the technology of wheat snacks based on the processes of extrusion and biocatalysis of proteins with specific proteases for the elimination of gluten is devepoped. The practical implementation of the technology will make it possible to obtain ready-to-eat snacks, which will be investigated for the preservation or elimination of antigenic properties during clinical trials.
Ultraviolet radiation has long proven itself as a technological process that allows you to reduce a significant amount or completely inhibit unwanted microorganisms, however, this technology is mainly used for disinfection of air and surfaces in industrial enterprises. The use of food processing with ultraviolet light is poorly developed, this is due to a number of limitations, one of which is the small depth of penetration of ultraviolet radiation. This circumstance introduces a number of restrictions and requires additional research for the active introduction of UV radiation in the food industry. The aim of the work: to study the dynamics of inhibition of native microflora of raw materials during UV treatment with various doses; to determine the degree of development of residual microflora during storage of UV-treated food products. Objects of research: model media containing native microflora of raw materials and fresh mushrooms. An improved UV treatment mode is proposed to reduce the surface injury of fresh mushrooms and ensure their microbiological stability of champignons during storage. The obtained results allowed us to establish the regularities of inhibition of native microflora on the surface of model media and fresh mushrooms depending on the distance to the UV radiation source, the time of irradiation, and the accumulated dose. It is noted that the dynamics of inhibition of native microflora on the surface of model media is not linear, and "Plateau" zones are marked. When developing a technology for processing fresh mushrooms, it is recommended to use a UV source with an accumulated radiation dose of 500 Dg/m2.
The use of physical methods of processing, in particular ultraviolet radiation, is used in the food industry for the purpose of disinfection of raw materials, semi-finished products and finished products, which increases the storage time. The process of processing food products with ultraviolet light quickly proved itself. This method does not change the taste of the product, increases the shelf life and sales, and is a non-thermal method of deactivating pathogens. The wide use of the bactericidal effect of UV rays for food products is limited by their low penetration capacity, so the UV spectrum can be used mainly for sur-face sterilization, provided that the deep layers of the material do not contain microflora. The effectiveness of UV radiation depends on the following factors: the source and the UV dose; the sensitivity of microorganisms to UV light; the composition and physical properties of the product. Object of research: model media containing native microflora of dried fruit raw materials "dried Apri-cots". The research was carried out using model media simulating the proper-ties of the raw material surface, excluding its protective mechanisms and allow-ing to reveal the true dynamics of inhibition of native microflora. Native micro-flora of dried fruits implies a set of microorganisms. Literature sources have shown the possibility of the presence of such types of microorganisms as E. coli, Salmonella, Candida, Pseudomonas, spore forms of microorganisms on the surface of raw materials. During the experiment it was determined that the treatment duration of 5 min reduced the initial contamination of 2 order pro-cessing in 10 minutes – 2.6 the order in 15 minutes – 2.7 order and 20 minutes for 3 orders of magnitude.
Most scientists agree that combining meat and vegetable raw materials is the most promising way to solve the problem of healthy eating. The combination of raw materials allows you to obtain a variety of high-quality products, expands the range and allows you to enter the optimal customized recipes to ensure the best consistency and biological value of the finished product. The article discusses the development of a technology for obtaining a functional food product using meat and vegetable raw materials. The aim of the study is to develop a combined food product for therapeutic, prophylactic and functional purposes. An improved recipe for rabbit meat paste with the addition of plant components is proposed. The developed technology was used to produce meat pastes based on a balanced ratio of the main food ingredients, providing improved digestibility, assimilability, biological value while achieving the best consistency. Rabbit meat is used as a meat component. Chickpea flour, onions, garlic, sesame oil, carrots, table salt, cloves, ground black pepper, paprika, broth and water were used as plant components. The broth obtained after boiling the rabbit is used. Quality assessment by organoleptic and physicochemical parameters was carried out according to generally accepted methods. This recipe made it possible to obtain a food product of a functional orientation, balanced in chemical composition, containing vegetable and animal proteins, fats, a sufficient amount of carbohydrates, vitamins A, C, E and such biologically significant elements as iron, calcium, potassium, sodium, magnesium, phosphorus, manganese, zinc, iodine, etc., with high organoleptic characteristics. The mass fraction of protein was at least 16.5%, fat - 17.2%, carbohydrates - 1.5%. The calorie content of 100 g of finished paste was 226 Kcal.
In the result of the analysis of domestic experience over the last 10 years of foreign experience (for example, 9 countries: Vietnam, India, Spain, Canada, China, Norway, USA, Chile, Japan, which possess the most advanced technologies and equipment for highly efficient production of feed for fish) in the development of innovative technologies and equipment for production of high-performance fish feeds were identified that the methods both dry and wet pressing are outdated and do not meet modern requirements in the production of fish feeds since it does not allow a deep physical-chemical transformations in protein-carbohydrate complex and exercise enter fat components at 40 %. Modern fish technologies are based on the use of extrusion processing of multicomponent mixture to give different buoyancy and adjustable rate of immersion of the resulting feed. Extrusion technology will allow to introduce a large amount of fat into the product - up to 35-40 %, to achieve 100 % starch splitting level. Based on the study of the nutrition of the canal catfish grown in the Central Federal District of the Russian Federation, the nutritional value of each of the components of the feed mixture, providing the need for fish to ensure a significant increase in the growth of live mass and improve the chemical composition of meat, was assessed for different age groups. To solve this problem, the "Feed Optima Expert" optimization program has developed products of extruded feed. Food needs of canal som: 30 - 40 percent protein, 4 - 6 percent fat, no more than 5 percent fiber, 35 - 40 percent Nosazotic Extract substances and 12 - 13 thousand kilos of Joule digestible energy in 1 kilogram (in recalculation on dry matter).
Ultraviolet radiation (UV radiation) has long been considered as a physical method of treating various surfaces, permitting to reduce the concentration of undesirable microorganisms significantly or completely inhibit their reproduction. UV radiation is most widely used for surface disinfection in medical and industrial organizations. Processing food products with UV radiation in order to achieve a sterilizing effect has a number of limitations. On the one hand, this is a low depth of penetration of ultraviolet radiation at its low intensity, on the other hand, a significant warming of processed products at high intensity of UV radiation, which can lead to the organoleptic properties degradation of processed products. For effective use of UV radiation in food processing, it is important to establish the dependence of changes in the dynamics of the death of microorganisms that can cause food spoilage on the intensity and time of UV radiation treatment of the surface of food products, provided that their organoleptic properties are preserved. The most sensitive types of food to UV-radiation treatment include vegetable rav’materials, in particular mushrooms. The purpose of this work is to study the dynamics of inhibition of native microflora of fruit bodies of mushrooms when they are treated with UV radiation at different doses and changes in the degree of development of residual microflora during storage of fresh mushrooms treated with UV radiation. Objects of research: model environments containing the native microflora of fresh Agaricus bisporus mushrooms, and directly fresh mushrooms. In the course of work, the optimal treatment mode (radiation intensity and processing time) of fresh mushrooms with UV radiation is established, which ensures the microbiological stability of fresh Agaricus bisporus mushrooms with minimal damage to the surface of the mushrooms and preserving their organoleptic properties during storage. The regularity of inhibition of native microflora on the surface of model media and the surface of fresh mushrooms is established depending on the distance to the source of UV radiation (UV-C lamp) and the accumulated dose. It is noted that the dynamics of inhibition of native microflora on the surface of model media is nonlinear and includes plateau zones. Treatment of fresh mushrooms with UV radiation doses at the level of 320 and 480 J/m2 allowed to increase the shelf life of mushrooms in comparison with control samples by 8 days. When developing the technology for processing fresh mushrooms, it is recommended to use a distance of 25 cm with an accumulated dose of 480 J/m2.
Many scientists and experts believe that combining meat and vegetable raw materials is the most promising way to solve the problem of healthy eating. The combination of raw materials allows you to obtain original high-quality food products of various compositions, expand the range of this type of product and allows you to use optimal customized recipes to ensure the best consistency and biological value. The article discusses the development of a technology for obtaining a functional food product using meat and vegetable components. The aim of the study is to develop a combined food product for therapeutic, prophylactic and functional purposes. An original recipe for rabbit meatloaf with the addition of plant components is proposed. According to the developed technology, the production of meat loaves was made on the basis of a balanced ratio of the main food ingredients, providing improved digestibility, assimilability, biological value while achieving the best consistency. Rabbit meat is used as a meat component. Chickpea flour, pine nuts, fenugreek seeds, paprika, table salt, black pepper were used as plant components. The quality assessment by organoleptic and physicochemical indicators was carried out according to generally accepted methods. This recipe made it possible to obtain a food product of a functional orientation, balanced in chemical composition, containing vegetable and animal proteins, fats, a sufficient amount of carbohydrates, group B vitamins, vitamins A, C, E, K, PP and such biologically significant elements as iron, calcium, potassium, sodium, magnesium, phosphorus, manganese, zinc, iodine, etc., with high organoleptic characteristics. The mass fraction of protein was at least 18.2%, fat - 13.0%, carbohydrates - 1.5%. The calorie content of 100 g of finished meatloaf was 183 Kcal.
Grain-based foods play an essential role in human nutrition. Cereal-based products contain soluble and insoluble dietary fiber, which, by reducing cholesterol levels, reduce the risk of cardiovascular diseases, as well as stabilize digestive functions, preventing diseases of the gastrointestinal tract. Grain products supply the human body not only with energy, but also with protein – by 30-40%, b vitamins by 50-60%, and vitamin E by 80 %. In preliminary studies, 4 types of extruded grain bases were identified from buckwheat, millet, lentils and chickpeas, defined as the basis for fermented dairy products. 20 experiments were carried out in each of the variants using extruded grain bases from buckwheat, millet, lentils and chickpeas with two variants of the milk base – milk with a fat content of 2.5 and 3.2 %. mathematical models of the response function dependences on the selected factors were Obtained, which allowed determining the optimal ratio of ingredients for each of the considered variants. Developed formulation of two dairy products with grain-based extruded from millet based on milk with 2.5% fat and extruded grain-based chickpea based on dairy products with fat content of 3.2%. According to physical and chemical parameters, all samples of fermented milk products met the requirements regulatory documents.
There has been a significant increase in the oat (Avena sativa. L) consumption recently due to the new scientific data on dietary properties of oats, high content of polyphenols, especially Avenanthramides, and some flavonoids with an antioxidant effect. However, the thick layer of the cell wall in the hypoaleurone area and the uneven distribution of nutrients over the kernel determine the need to find effective technological solutions for their use in food production. The use of whole grain and its sprouting could be one of the possible solutions. Sprouting breaks difficult to digest grain complexes, thus making nutrients available for plant development and easier for human body intake. In the framework of this study, we propose to activate the process of grain sprouting by ultrasonic treatment of water used for preliminary grain soaking. The research results revealed that the proposed method accelerates accumulating of polyphenolic substances, phenolic acids and total antioxidant capacity. The mass fraction of polyphenolic substances in Avena sativa L. samples preliminarily aged in water treated with ultrasound (315W) for 2 minutes was 2.811 mg CAE/g, which is 4.64 times more than the mass fraction of the reference non-sprouted sample. Accumulation of phenolic acids at different treatment modes was intensified by 30.5% and more compared to the non-sprouted grain. Mathematical processing of the total antioxidant capacity (DPPH) results established a reasonable mode of ultrasonic water treatment used for grain soaking - 400 W for 2 minutes, the total antioxidant capacity will be 2.254 mg TEAC / g. Thus, the ultrasonic effect can be recommended as an intensifier in grain sprouting.

The article discusses in detail the membrane processing of complex systems, reverse osmosis (RO) and electrodialysis (ED) membranes. Currently, the development of industrial wastewater treatment technologies is of great interest to many researchers. This is due to the fact that the food, pharmaceutical and chemical industries are becoming increasingly important in our lives, while exacerbating one of the most serious environmental problems, environmental pollution from industrial wastewater, which contains harmful substances in high concentrations. This study is devoted to the analysis of a new technology for the extraction of complex components from industrial wastewater, combining reverse osmosis and electrodialysis. Reverse osmosis systems are pressure controlled membrane separation processes. In contrast, an electrodialysis system is an electrochemical process that is commonly used industrially under normal atmospheric pressure. However, such membrane processes have a significant drawback, the working membranes are contaminated with suspended substances in the wastewater and lose their activity. Therefore, to maintain the activity of the membranes for a long time, it is necessary to pre-treat wastewater by removing suspended solids. The analysis of the recovered components opens up new perspectives for the recovery of industrial wastewater. There is a wide range of methods for pretreatment of water for reverse osmosis and electrodialysis. Ultrafiltration (UF) followed by reverse osmosis is an important process for separating organic and inorganic compounds from wastewater. This article discusses some of these methods. In conclusion, it should be noted that electrodialysis demonstrates remarkable technical advantages in the treatment of concentrated solution after RO.

The paper attempts to analyze the problems of adjusting the educational process in the EurAsEC countries that have arisen in recent decades in case of unforeseen circumstances. At the end of the 20th century, the ideas of globalization of all areas of the world community's activity led in the field of higher education to a thirst for immediate changes. What prompted the concern of the leading universities in Europe, which train highly qualified for the real sectors of the economy? An analysis of the current situation showed that the realities existing at that time pushed people to action, since analysts of higher education have repeatedly noticed that in the field of many areas of fundamental research, Europe is significantly inferior to the United States. Also noteworthy is the identity of the Nobel laureates. Independent commentators, beyond any emotion, pointed out that the United States has always invested significant amounts of money in the development of science. These problems gave rise to the Bologna process of reforming higher education in Europe. In this regard, the problems are considered and the prospects for the creation and development of a single educational space on the territory of the member states of the Eurasian Economic Union, considered by the authors as an important component of economic integration in the post-Soviet space, are identified. From the standpoint of taking into account foreign experience, as well as existing elements of educational integration within the framework of such associations. as EurAsEC, SCO, CIS, the main directions of integration interaction in the field of education of the EAEU countries are highlighted. The authors made attempts to formulate ways out of the current situation in the Eurasian educational space, especially in cases of unforeseen environmental conditions, such as a pandemic. Although in the educational space under consideration, the state of affairs with the organization, and in particular with funding, research and science is worse, this should not lead to ignoring the interests of both the students themselves and educational organizations in general. Insufficient funding is aggravated by many other factors, which together lead to the conclusion that EurAsia needs innovations designed to “modernize” the structure of education.
The article summarizes and systematizes modern high-tech digital tools that allow modeling the behavior of a modern consumer and ensuring the efficiency of the functioning of trade enterprises by increasing sales. It has been established that merchandising has an impressive arsenal of high-tech tools, which include: projection showcase, interactive showcase, virtual shelf, 3D showcase, Aislelabs and Prism Skylabs devices, mobile applications, Fetch Robotics and Lowe's robots, ERP system, Amazon Prime Air system, etc. A projection showcase is a showcase glass (screen) covered with a special film (opaque, translucent or completely transparent) of rear projection. A projector is installed behind the screen, which transmits an image to the screen, which is clearly visible from the outside. An interactive showcase (interactive wall, touch showcase) is a video screen that interacts with a person; most often, they use multitouch technology (touch showcases) and contactless sensor technology (Kinect showcases). A virtual shelf is an LCD panel or video wall, with a Kinect system attached to the back, which “reads” human movements and allows you to control the system from a distance. The 3D showcase is an electronic counter with technology that allows 3D images to be literally projected in the air, combined with motion sensors. The motion sensor allows the showcase to react to the trajectory of passers-by, that is, the showcase is static as long as no one walks past it, and as soon as the sensors detect the movement of a person in the reach, the showcase comes to life, the colors, lighting, picture change. Digital technologies in retail are a new interactive advertising tool for attracting and retaining customer attention. Due to the effect of surprise inherent in all interactive solutions in advertising, virtual showcases (interactive walls) attract attention, keep the visitor for a long time, stimulate to make a purchase or receive information.
The article is devoted to the study of the influence of the development of innovations on the economic security of the regions. Based on the assumption that innovative development plays a key role in the process of ensuring the economic security of the region, the authors proposed a system of indicators for assessing the innovative component of the economic security of the region, including the indicators of economic security reflected in the Decree «On the Strategy of Economic Security of the Russian Federation for the Period up to 2030». The impact of innovations is realized through the achievement of the goals of ensuring the country's security, among which is the dynamic and progressive development of the economy. The authors proposed a methodology for assessing the innovative component of economic security based on the scoring method, developed an assessment scale for interpreting the results of calculations, assessed the innovative security of regional economic systems of the Federal Districts of Russia for the period 2015–2019. As a result of the analysis, factors were identified that hinder innovative development and negatively affect the provision of economic security at the regional level: underdevelopment, low efficiency of the innovation infrastructure, reduction of internal costs for research and development, a decrease in the number of developed advanced production technologies, and others. It has been established that the economic security of a region depends on its ability to perceive innovations, while institutional factors have a significant impact on the pace of development. The work has improved the methodological tools for diagnosing the innovative security of the regions of the Russian Federation by optimizing the system of criteria for its assessment. The results of the empirical studies carried out confirmed the possibility of practical use of the developed methodology for diagnosing the innovative security of the regions of the Russian Federation and identifying priority areas for its improvement.

The transition to a new format of interaction using digital technologies, the digitalization of the economy, the use of artificial intelligence, the rapid and widespread change of generations in business that have their own characteristics in relation to the forms of work, various abilities to master and apply modern technologies and knowledge, and other factors are currently changing the nature of relationships in the "business management - personnel"system. Thanks to the digitalization of the economy, both new opportunities and new challenges are emerging in project management at the same time. The article examines the main trends in the digitalization of the economy, which generate fundamental changes in project management. Currently, digital technologies that directly affect the effectiveness of project management have been developed, such as artificial intelligence, the Internet of things, wireless communication technologies, digital production, big data, and blockchain. Thus, the conducted research allows us to conclude that for effective project management in the conditions of digitalization of the economy, it is necessary to correctly determine the most effective and timely tools
Currently, one of the priorities of the country's development is the transition of the economy to an innovative path of development. Analysis and evaluation of innovative development at the regional and national levels, quantitative assessment of regional innovation activity, and development of methods for evaluating the effectiveness of interaction between science and business that allow choosing the right strategies for solving management problems are of particular relevance. The subject of the research is the indexes of innovative development of regions. The purpose of the study is to compare the indexes of innovative development of regions and identify indexes that do not have significant differences. Eight indexes describing the innovative development of Russian regions are compared. We use four of the author's indexes, published earlier: the index of technical efficiency innovative space for international patent applications TEMPZ, the index of technical efficiency innovative space for patent applications TEPZ, the index of technical efficiency innovative space issued patents TEPV and the index of technical efficiency innovative space developed for new technologies TETECH. Along with the author's indexes, four other indexes with a similar applied focus are considered, published by the Institute for Statistical Studies and Economics of Knowledge (ISSEK) in National Research University — Higher School of Economics (HSE), RIA rating, and Association of Innovative Regions of Russia (AIRR). In the course of the study, a comparative analysis of the indexes of innovative development in the space of expert-defined characteristics of regional differentiation was made. Analysis of the cosines of the angles between the indexes constructed using the beta coefficients of the regressions of these indexes on the differentiation characteristics allows us to refine the results of correlation analysis and identify a subset of indexes that are not distinguishable when solving control problems parameterized using the differentiation characteristics.
The article discusses the integration of additive technologies into production, presents the advantages and disadvantages of 3D metal printing. The data of the current indicators of the effectiveness of technological processes when using 3D equipment are analyzed, the difficulties of introducing additive technologies into production processes are determined.

Small-scale production is gradually being introduced into additive manufacturing, which has distinctive characteristics for the mechanical engineering industry. The introduction of such technological equipment provides an opportunity to speed up the manufacturing procedure, improve the properties of the product, despite the high cost (0.8-1.5 million euros). At the same time, from a strategic economic position in comparison with classical technologies, high-tech engineering solutions act as highly competitive.
The article deals with the problem of processing Apple waste in production. It is shown how efficiently food production can be organized with the least losses and costs. It is proved that the technogenic type of development formed in the world economy, which does not sufficiently take into account the environmental and social costs of economic activity, reproduces the problems and dangers that threaten human civilization. Humanity is caught in a vicious circle: to create comfortable living conditions, it is necessary to increase the volume of gross domestic product, which requires more and more resources (primarily mineral), and their extraction, processing and consumption cause serious damage to the environment, contributing to the deterioration of living conditions and the growth of diseases, which negates efforts to create living comfort, and threatening climate change can make life on Earth itself problematic. Within the framework of lean management, the effectiveness of the process of obtaining Apple powder from waste is considered. Development of technologies for processing Apple pomace is an important task, the solution of which is necessary for the improvement of economic indicators of resource efficiency main by-products of fresh Apple pomace in the form of pectin containing products (extracts, pastes, powders, gelling concentrates); canned fruit (pur?ed foods, jam, secondary juice); drink (alcoholic and nonalcoholic); Apple powder; phenolic compounds; products of fermentation (food grade organic acids, enzymes, high-protein animal feed), etc. The use of resource-saving technologies will help strengthen the competitive advantages of industrial enterprises.
