Nowadays a healthy diet plays a very important role in the nutrition of people of every age group. In the context of constant growth in demand for healthy food products, it is important to expand the range of products with functional properties. Naturally enriched foods can not only maintain health, but also improve it. Pectin extract is a natural complexing agent, capable of removing toxic substances, heavy metals and radionuclides from the body. It is also an essential source of dietary fiber. The goal of the research was developing bakery products with dietary supplements for a healthy diet. The objects of the research were premium wheat flour and pectin extract obtained from beet pulp, a secondary raw material resource in the production of sugar. When designing new bread products with beet pulp extract, the recipe of traditional wheat bread was taken as a basis. It has been revealed that bread containing beet pulp extract in its recipe in a dosage of 10% by weight of flour has indicators that contribute to the formation of high-quality finished products. This product can be used by all age groups of the population for preventive purposes.

The obtained results can be used in any food production involved in the design and production of enriched bakery products using innovative technologies.

It is obvious that secondary raw materials resulting from the industrial processing of partial fish species, in particular, the roe film-caviar complex, can be widely used for the production of various food products, including functional ones. There is an obvious need to conduct research on the chemical composition of the roe film-caviar complex of silver carp, carp, pike perch and catfish, which will allow us to adequately evaluate rational approaches to the production of phospholipid and protein products from them that are in demand on the market. The purpose of the research was to study and analyze the chemical composition and energy value of the roe film-caviar complex of silver carp, carp, pike perch and catfish in order to extract valuable substances from it. Data on the total lipid content in the roe film-caviar complex of pike perch and catfish are practically not provided, however, the indicators for catfish eggs and those obtained experimentally almost coincide, but for pike perch there are differences. The identified concentrations of total protein in the composition of the studied caviar make it possible to recommend its use in the technology of protein isolates and textures. The total content of minerals (ash) in the roe film-caviar complex is higher than in fish meat, and averages 1.5...2.0%. The results obtained for determining the mass fraction of ash in the roe film-caviar complex of silver carp, carp, pike perch and catfish can be considered quite satisfactory. Analysis of data on the chemical composition and energy value of the roe film-caviar complex of silver carp, carp, pike perch and catfish, which according to morphological characteristics correspond to the IV stage of maturity, shows that in terms of the chemical composition these products belong to high-protein raw materials, while the caviar of all of the above fish, except, perhaps, pike perch, it also belongs to fatty raw materials, while the calculated energy value does not allow this raw material to be classified as dietary.

Investigation of inulin and the possibilities of its use is a relevant and important scientific and practical task. The goal is to study the features of the structural organization of inulin and analyze the possibilities of its use. The object and methods of the research. The object of the research was inulin obtained from Jerusalem artichoke roots. Photography (macro photography) was carried out using a SONY NEX-5N camera (Thailand). The microstructure was studied using an Olympus CX41RF light microscope (magnification 40, 100 and 400 times), ALTRA 20 Soft Imaging Sistem camera (Japan). IR absorption spectra were recorded on a Perkin Elmer Spectrum 1000 single-beam Fourier spectrometer in the spectral range of 400–4000 cm–1 with a spectral slit width of 4 cm–1; the recording time for one spectrum was about 2 min. The literature search on the problem was carried out in the databases of RSCI, Google Scholar, ResearchGate, PubMed using keywords and phrases: «inulin», «inulin structure», «inulin properties», «use of inulin», «fructo-oligosaccharides».

The results and their discussion. Analysis of the IR spectrum has confirmed that inulin is a polysaccharide consisting of fructose residues. Studies of the morphology of inulin using light microscopy have shown that inulin is organized in the form of pseudocrystalline formations. In a medium of 96% ethyl alcohol, the central (in the form of a dark circle) and peripheral parts (in the form of a translucent circle that envelops the central dark circle), as well as small parts of inulin (in the form of dark dots) separating from the main pseudocrystalline formations, are clearly visible. There is a wide variety of foods fortified with inulin. It has been established that inulin concentrations used for food fortification vary widely depending on the type of food product, ranging from 0.75 to 50%. The prebiotic effect of inulin has been proved, but its interaction with various food matrices is a complex process, and it is not always technologically beneficial for the product. In addition to sensory, physicochemical and rheological characteristics, it is also necessary to measure characteristics such as prebiotic content of foods and determine prebiotic activity in vivo and in vitro, as well as evaluate potential adverse reactions in order to determine scientifically based doses of inulin for consumers.

Conclusion. The obtained IR spectrum confirms the known chemical structure of inulin. Morphological studies of inulin using light microscopy indicate the creation of pseudocrystalline formations by inulin in a medium of glycerol and 96% ethyl alcohol. Inulin can be widely used in various foods as an important biologically active substance.

The purpose of the research is to evaluate flavor compositions formed during the action of high temperatures on individual processes of the technological scheme for the production of vegetable semi-finished products and complex interaction in the structure of the finished product, taking into account the use of carbohydrate-protein fillers. The research presents some features of the flow of physicochemical reactions that make it possible to describe the dynamics of the interaction of nutrients in the formed binary compositions of carbohydrate-fat structures of plant systems in the process of temperature exposure. The methods used. To carry out the tests, the potentiometric method was used and the pH of each sample was determined using the Expert-001-3pH device. Determinations of sugars were carried out according to GOST 8756.13-87 using the permanganate method; dry substances according to GOST 31640-2012; organoleptic assessment according to GOST ISO 6658–2015. The objects: samples of semi-finished products containing 12, 24, 36% carrots and 4, 8, 12% onions. The results. It has been established that sauteing treatment promotes the formation of a complex of flavoring and aromatic substances, depending on the type of vegetables. With increasing intensity of processing, the concentration of carbohydrates in the sautes increases, as well as the amount of dry matter. It has been found that in all samples the amount of organic acids increases with increasing temperature, pH decreases in carrots from 6.0-6.3; 5.5-7.0 to 4.2-5.9, and onions from 5.5-6.1; 6.4-7.9 to 3.0-5.0. For clarity of experiments, graphs of the dependence of the processing intensity on the amount of dry substances, carbohydrates, tissue softening and the formation of the flavor and aromatic range have been presented. Conclusion. The experimental data and dependencies obtained will be useful when considering more complex processes of mass transfer, sucrose inversion, and destruction of protein-carotenoid complexes. The perception of raw carrots is complex: the balance between sweetness and bitterness, which are the main criteria for the sensory quality of carrots. It intensifies when sauteed. A richer sweet taste appears. This perception of sweetness is determined by the ratio: sugar and bitterness. It does not have a direct correlation with the total sugar content in samples with carrots and sautéed onions.

According to global analytical agencies the most promising area of development of the food industry is the enrichment of food products with physiologically functional ingredients – dietary fiber, vitamins, minerals, etc. Analysis of the market for functional ingredients indicates the prospects of organizing the production of domestic inulin and other biologically active components from various anatomical parts herbaceous tuberous plant of the Sunflower genus – Jerusalem artichoke, the distinctive features of which are high yield of tubers, unpretentiousness to cultivation conditions, resistance to diseases and pests. The purpose of the research was to develop a technology for the production of inulin and chlorophyll from Jerusalem artichoke tubers and leaves. The work used generally accepted physical and chemical methods for studying plant objects. The results of the research made it possible to establish optimal technological parameters for the process of extracting inulin from Jerusalem artichoke tubers with a 60% aqueous-alcohol solution. The technology has been proposed for the production of inulin from Jerusalem artichoke tubers, based on the fractionation of a mixture of components with different molecular weights, by passing them through polyamide composite membranes of reverse osmosis roll type. It has been established that the molecular weight of inulin isolated from Jerusalem artichoke tubers of the «Interes» variety is 5.84 kDa. It has been revealed that Jerusalem artichoke leaves contain a and b chlorophyll in amounts of 6.98 and 0.74 mg/g of wet matter. Copper chlorophyll derivatives isolated from Jerusalem artichoke leaves are promising not only as food colorings, but also as biologically active substances with a wide spectrum of action. The target products obtained using the proposed technology – inulin and copper derivatives of chlorophylls – can find wide practical application in the food industry and in public catering.

High sugar consumption leads to such socially significant diseases as type 2 diabetes, osteoporosis, obesity, metabolic syndrome, and cardiovascular diseases. The problem of replacing sugar in food products and finished culinary products is always acute for food manufacturers. In the future the demand for intense sweeteners and sugar substitutes is expected to increase, as the demand for dietary preventive, sports and diabetic nutrition products in the Russian Federation is steadily growing. The wide selection of sugar substitutes available on the market is due to their significant economic advantages, high sweetness factor, ease of use and the absence of negative effects on the human body, since they do not contain glucose and do not lead to sharp fluctuations in blood sugar. Their use allows us to create innovative products, take into account the needs of different consumer groups and follow modern requirements for a healthy lifestyle. An important indicator in the production of sugar substitutes is their quality characteristics. The purpose of the research is commodity assessment of the quality of four most popular liquid sugar substitutes for compliance with labeling in accordance with the technical regulations TR CU 021/2012, microbiological indicators, examination of samples for the presence of sweeteners, and preservative content. It has been established that all the studied samples violate the requirements of the current legislation, starting with typos in the declaration of conformity (Slastya-super), ending with unreliable information on the label («Mastershape»^TM, «Nosugar», «Sladkiy pshik»^TM), excess concentration of preservatives above the permitted limits («Sladkiy pshik»^TM) and microbiological purity («Mastershape» and «Nosugar»).

Currently, to make profit all entrepreneurs expand the range of products. The purpose of the research is introduction and use of a combination of different types of flour in bread baking in order to expand the range of bakery products of improved quality. The objectives of the research are to study the organoleptic quality indicators of the experimental sample; to conduct a study on physical and chemical quality indicators of the experimental sample; to determine the economic feasibility of using a new recipe in bread production. The research was carried out on the basis of the Department of Processing Technologies and Food Security of Volgograd State Agrarian University. To expand the range of bakery products, 40% of corn flour and 10% of buckwheat flour were used to replace 50% of wheat flour. The bread was baked using the non-steam method. When conducting an organoleptic assessment of bread, the experimental sample complied with the requirements of GOST 27669-88 «Wheat baking flour. Method of trial laboratory bread baking.» The taste became sweeter, the porosity became fine and thin-walled, and the color of the crumb became light brown. According to physicochemical indicators, the experimental sample was 56 g larger in bread volume, and the crumb moisture content was 43%. The economic efficiency of bread production was calculated. The profitability of experimental bread production was 44%, which was 14% higher than the control (wheat) sample.  I t is recommended to produce bread using a combination of three types of flour, to increase the output at enterprises. This type of bread, in terms of organoleptic and physico-chemical indicators, has proven itself to be a more advantageous example of a bakery product compared with wheat bread.

The article investigates the development of functional confectionery products. It seems relevant to use non-traditional recipe components with increased nutritional value. As a basis for the design of such food products, pastille products containing technologically necessary and useful functional components – protein and pectin – are proposed. A promising source for replacing sugar is fructose-glucose syrup. The object of the research is pastille products with increased nutritional value using non-traditional recipe components. Quince was used as a fruit filling for marshmallows. Expanding the range of plant raw materials used in the production of pastille products, it is advisable to use legumes, which supposedly have a high foaming ability due to the presence of a complex of surfactants in their composition. Legumes are characterized by high nutritional value, have a wide distribution area and are included in the diet of the majority of the Russian population. The purpose of the research is to develop a confectionery sugary product with a whipped structure – marshmallows of increased nutritional value using processed legume products – aquafaba, as well as fructose-glucose syrup. In the course of experimental studies conducted at the Department of Public Nutrition and Service of the Kuban State Technical University, the authors substantiated the choice of non-traditional raw materials to be included in the recipe composition and technology for the production of marshmallows with increased nutritional value. Research has been carried out and the process of foaming and foam resistance of dispersed systems based on aquafaba of canned chickpeas has been optimized. The technology and the recipe for marshmallows with increased nutritional density have been developed based on quince puree, aquafaba, canned chickpeas and fructose-glucose syrup. The main consumer properties of the finished product have been studied: organoleptic characteristics, chemical composition, nutritional value, hygienic safety indicators. The conclusions: in the development of confectionery products, an increase in their nutritional value, a reduction in calorie content, and the replacement of sucrose with sweeteners of natural origin have been achieved, which makes it possible to recommend them for inclusion in the diet of people suffering from diabetes.

A pressing issue in the food industry is providing the population with adequate nutrition. According to the concept of healthy eating, a person needs to increase the consumption of plant foods without reducing the consumption of foods containing complete protein. We have created dry fish and plant products, in the form of food concentrates, containing all the necessary macro- and micronutrients. The purpose of the research was to study the influence of plant components on the microbiological and oxidative processes of dry fish and fish-plant products during storage. To achieve the intended goal, the tasks of determining microbiological indicators and oxidation products at the beginning and end of the storage period were solved. Storage of dry fish and plant products was carried out for 12 months in polymer packaging at a temperature of plus 20±5℃. All analyses were carried out using generally accepted standard methods. As a result of the studies, it was established that the microbiological indicators of a dry fish-plant product, due to the addition of vegetables and corn flour, were higher than those of a dry fish product (0.5x10⁴ and 0.2x10⁴ CFU per 1 g, respectively), but during storage the bacterial contamination of dry of fish and plant products decreased from 0.5x10⁴ to 0.1x10⁴ CFU per 1 g of product. Also, plant components affected the oxidative processes in dry fish and vegetable products. The acid number in samples of dry fish product increased from 0.71 to 2.67 mg of KOH, and in samples of dry fish-plant product – from 0.65 to 1.87 mg of KOH after 12 months of storage. Thus, plant components inhibited the oxidation process and maintain the quality of the product during storage.

Liquor products are represented by a wide range of drinks. Despite this diversity, they are all united by the use of semi-finished products (alcoholic juices, pestilences and infusions) during blending. Extraction of components of plant raw materials is one of the key processes for obtaining semi-finished alcoholic beverages. The quality indicators of the finished liquor product directly depend on their composition and quality. The purpose of the research is to study the vibration effect as a physical method of intensifying the process of extracting flavoring and aromatic compounds of fruit and berry raw materials when obtaining semi-finished products for distillery production (infusions and juices). To study the effect of vibration exposure on the content of substances responsible for taste, such technical factors as frequency (f), amplitude (A) and duration (τ) of exposure have been taken into account. The mass concentration of phenolic and coloring substances has been taken as controlled indicators. The processing was carried out on the installation developed at the Department of Winemaking and Fermentation Technology named after Professor A.A. Merzhanyan of FSBEI HE «KubSTU». The research was conducted on semi-finished products obtained from raspberries and cherries in the process of obtaining alcoholized components of a blend of liqueurs. In this case, the ratio of components was equal to 1:1. A comparison of the indicators was carried out with a sample obtained by stationary infusion. The positive influence of vibration during the extraction process with aqueous-alcohol solutions on the quality indicators of semi-finished products was established. Optimal processing parameters were also determined to reduce the duration of the process. The data obtained allow us to judge the feasibility of using vibration in the alcoholic beverage industry as a technique that accelerates infusion and improves the quality of semi-finished products.

Prevention of nutritional diseases with the help of functional foods remains relevant. Therefore, the development of food technology using raw materials that contribute to the formation of functional properties is relevant and has scientific and practical significance. The object of the research was every day product, i.e. bread made from premium wheat flour. In order to form functional properties non-traditional plant raw materials were used to enrich bread – dandelion root, characterized by a high content of prebiotic substance – inulin. The purpose of the research was to substantiate the creation of bakery products for a wide range of consumers, enriched with wild plant materials with functional properties. Organoleptic evaluation was carried out in accordance with GOST R 53161-2008; dietary fiber content according to GOST R 54014-2010; vitamins according to the General Pharmacopoeia. 1.2.3.0017.15. As a result of laboratory baking, experimental samples of bread were obtained from premium wheat flour containing dandelion root powder in the recipe in amounts of 5, 10 and 15%. An organoleptic assessment of the quality of the prototypes made it possible to justify the choice of a bread recipe made from wheat flour with the addition of dandelion root powder in an amount of 5%. A larger amount contributed to the appearance of a bitter taste, a specific herbal odor and the formation of uneven porosity of bread and dense crumb. Adding dandelion root powder to the recipe for bread made from wheat flour helps to increase the content of dietary fiber in the finished product by an average of 1.5 times for every 5% of added powder, as well as increasing the content of vitamins B1, B2 and B5. The developed type of bread can be produced at any bakery, as well as public catering enterprise, which will help expand the range of functional food products.

Currently, the key trends in the global food market include the rapidly developing functional nutrition industry, which is of great interest to consumers. Inulin is a natural polysaccharide of plant origin, consisting of residues of E-fructofuranose (fructose). The object of the research is inulin extract from Jerusalem artichoke at different humidity levels. It has been established that to intensify the drying process of inulin extract, it is advisable to increase the mass transfer surface, which can be achieved by spraying the initial product, and using volumetric energy supply methods, in particular, radiation energy supply. The important and most energy-intensive stages of drying are carried out in the hygroscopic area of equilibrium humidity of the object of the research, which determines the intensity and mechanism of the dehumidification operation in order to increase the degree of perfection, select rational operating parameters, adapt to the object of the analysis and solve a mathematical model of removal moisture from it. Based on the sorption isotherms and hygroscopic parameters of the inulin extract obtained in preliminary studies, obtained by dehydrating the inulin extract from Jerusalem artichoke (variety «Skorospelka», grown by JSC «Chaganskoe», the bAstrakhan region), a thermodynamic analysis of the process of sorption and desorption was carried out in different ranges of humidity variation. The total binding energy of moisture with the dry residue of inulin and its thermodynamic components were found. The data obtained do not contradict known literature sources and can be recommended when designing processes for removing moisture from inulin extract and designing drying devices.

The industry of gluten-free bakery products has not been studied properly, so this topic is gaining popularity among scientists. The subject of the research was the development of recipes for gluten-free flour mixtures. To improve the taste characteristics of the product and increase the biological value, it was decided to introduce plant raw materials non-traditional for bread. Chia seeds and carrot powder were chosen as additives. The goal of the research was to develop recipes for gluten-free flour mixtures. The research was carried out in several stages: 1. determination of the component composition of the gluten-free mixture recipe and production of prototypes; 2. analysis of organoleptic indicators; 3. carrying out physical and chemical studies of dough and finished products. To carry out the analysis instrumental and visual research methods were used. During the experiment three samples of bread were obtained from different types of gluten-free flour (No. 1 – green buckwheat; No. 2 amaranth flour; No. 3 – gram flour) in combination with rice flour, carrot powder and chia seeds. The control sample was bread made from rice flour, potato and corn starch. The rate of dietary fiber supplementation was calculated on the basis of the recommended daily intake. Thus, 2.8 g of dietary fiber was added with carrots, and 4.4 g of dietary fiber with chia seeds. According to all the studies carried out, sample No. 3 from gram flour turned out to be the best. The research results can be used in the baking industry to expand the range of bakery products. A mixture for making gluten-free bread can be a very useful product, especially for those categories of the population who have a need for such products. Also, given that for the majority of the population bread is a commodity of everyday demand, the production of such mixtures will be in great demand.

As a result of scientific research carried out on the materials and technical base of KubSAU named after. I.T. Trubilin and MSTU technological parameters and biological value of quail meat has been studied. Texas broiler quails, which were raised on a farm in the Krasnodar Territory, were slaughtered. The rationale for the use of Texas broiler quail meat in the technology of special-purpose meat products has been given. Studies of technological properties showed that the slaughter yield of an uneviscerated carcass is on average 85%. The yield of boneless meat was assessed in two ways: after gutting and after blanching the carcass, which showed that the yield of boneless meat after blanching was higher by 16.87 g, which was explained by a more thorough separation of muscle tissue from the bones. The results provided the basis for the use of blanching of whole carcasses in the production technology of special products based on quail meat. The recipe composition of meat cream based on quail meat and offal was modeled. Experimental batches were developed, followed by a tasting assessment and calculation of nutritional value, which showed high results, which justified the use of Texas broiler quail meat for the production of products for both general and special purposes.

The article discusses the possibility of using such plant raw materials as pumpkin varieties of Michurinskaya, Krasnaya Malyshka and hybrid Azhur medoviy F1, calendula flower powder, corn flour when designing new types of multicomponent chips ensuring the principle of resource saving due to the involvement of apple production pomace in the technological process juice. A comprehensive analysis of plant raw materials used in the production of chips was carried out for the total content of antioxidants, polyphenolic composition (flavonols, catechins, anthocyanins), the presence of ascorbic acid and beta-carotene. Among the varieties and hybrids of pumpkin, in terms of the total content of water-soluble antioxidants, Krasnaya Malyshka and Azhur Medoviy F1 stand out, then apple pomace, corn flour are ranked in increasing antioxidant value, and the leader here is calendula flower powder. The content of polyphenols in the hybrid Azhur medoviy F1 is higher than in the varieties of Michurinskaya and Krasnaya Malyshka by an average of 42%. The maximum content of ascorbic acid was found in Krasnaya Malyshka pumpkin, but at the same time this variety is inferior in beta-carotene content to two other varieties Michurinskaya and the hybrid Azhur medoviy F1 by 58 and 54%, respectively. Apple pomace can act as an additional source of ascorbic acid and flavonols, calendula flower powder – ascorbic acid, polyphenols and beta-carotene, and corn flour – flavonols, catechins and beta-carotene. All pumpkin varieties and hybrids studied in the work ensure that the finished multicomponent chips, taking into account the established recommended consumption rate – 30 g per day, contain functional ingredients – ascorbic acid, beta-carotene and flavonols at a level of more than 15% of the physiological consumption rate per day.

In recent decades interest in hemp seed concentrates, which are characterized by a valuable amino acid composition and high nutritional value, has increased. Hemp seeds are sources of vegetable protein and essential components for maintaining health due to the rich content of protein compounds, vitamins, and unsaturated fatty acids. So, production of protein concentrates from oilseeds is becoming relevant. Taking this into account, it is relevant to conduct research aimed at developing and improving the technology for obtaining protein products from the seeds of industrial hemp Cannabis Sativa L of modern selection, as well as expanding the possibility of their use as a part of a different range of food products. The seeds of industrial hemp Cannabis Sativa L of modern selection were used as objects of the research. The studies used both generally accepted and special chemical, physicochemical and physical methods for studying the quality of raw materials and finished products. The research was carried out to improve the technology for obtaining protein concentrate from the seeds of industrial hemp Cannabis Sativa L. based on mathematical modeling of the process, which showed the greatest efficiency in extracting protein concentrate using a 20% alcohol solution as an extractant. Analysis of the composition of the resulting protein concentrate showed a predominant content of globulins. At the same time, the composition of globulin fractions, in comparison with albumin, indicates a great potential for the use of globulin in the formulations of functional food products, as well as a component of targeted technological action. In general, the studies have shown the feasibility of using protein concentrates from industrial hemp seeds of Cannabis Sativa L of modern selection in food products as a functional and technological ingredient.

The production of grain bread is of great practical importance for providing consumers with quality food products. Whole grain bread is a source of carbohydrates, protein, vitamins and minerals necessary for a healthy diet. This study examines the optimization of the production technology of grain bread using electrically activated water. Electroactivated water is an effective tool that allows you to regulate the quality of the finished product. In this regard, the goal of the research was to optimize the technology for the production of grain bread using electrically activated water, assessing its quality characteristics and safety indicators during storage. The objects of the study were wheat grain of the «Tabor» variety; fractions of electroactivated water (anolyte and catholyte); semi-finished products; ready-made grain bread samples. On the basis of a comprehensive assessment a sample of bread was selected, made from dispersed grain based on a dough made from a composite mixture with preliminary soaking of the grain in electrically activated water (anolyte). A technological scheme for the production of grain bread was developed. It has been established that the use of electrically activated water helps to reduce crumbling during storage.

The steady trend towards the production and consumption of functional foods is a hallmark of modern times. Among them fermented milk products, including cottage cheese, have a big share. Antioxidants, in particular betaine, are used for the fortification of food products. Betaine is proved to have a wide range of health benefits. The recommended intake of betaine is 131 mg/day, however, to exhibit a functional effect on the human body, its daily dose must reach 1500 mg. The actual consumption of betaine in food products is much lower, which necessitates the need to enrich daily diet products with betaine, in particular cottage cheese. The possibility of improving the composition of cottage cheese in terms of antioxidants, dietary fiber and the microelement silicon, thanks to the addition of the drug acidin-pepsin, has been experimentally proven. The preparation acidin-pepsin is added at the rate of 5 g per 100 kg of milk. This amount of the preparation contains 4 g of betaine hydrochloride, 10 mg of pork pepsin; and excipients, i.e. 240 mg of povidone-K25 240, 104 mg of colloidal silicon dioxide, 50 mg of calcium stearate, up to 12.6 g of sorbitol. The yield of cottage cheese from 100 kg of milk is 30.0 – 30.5 kg. The use of this technology will increase the shelf life of the finished product, expand the range of enriched functional products, since when using the preparation acidin-pepsin, cottage cheese is enriched not only with the antioxidant betaine, but also with dietary fiber povidone, calcium stearate, sorbitol and the microelement silicon.

The article is devoted to the research in the field of using frozen grapes in the technology of production of products for a healthy diet. The main objectives of the research are to substantiate technological significance of frozen table grapes for the development of functional desserts. To study the influence of negative temperatures on the gelling and complexing ability of pectin substances in frozen grapes with subsequent defrosting of the raw material. The object of the research was table grapes of 5 varieties grown in the Krasnodar region. Experimental studies of technological and biochemical parameters of fresh and frozen grapes in order to study and confirm the use of grapes in the food industry for the development of desserts with different functional areas were carried out on the territory of the Kuban State Agrarian University named after I.T. Trubilin in the laboratories of the Faculty of Food Production and Biotechnology. Biochemical methods of analysis, generally accepted in the food industry, were used as research tools. It is well known that low-temperature freezing helps to maximize the preservation of the nutritional value of plant materials, however, in the health food industry, recipes and technologies for processing frozen grapes are practically not represented. An information search of scientific literature has shown that there are no studies on the study and selection of grape varieties for canning by freezing and the production of functional products from defrosted raw materials, which indicates the need to conduct experimental studies, study the kinetics of the chemical and biochemical composition of fresh, frozen and defrosted grapes in order to differentiate raw materials for the production of desserts with different functional orientations. Using biochemical analysis methods, it has been established that, regardless of varietal characteristics, the main components of the chemical composition of grapes are preserved during freezing and further defrosting.

Modern Russians do not receive enough polyunsaturated fatty acids in their diet, as well as more than half the recommended dietary fiber intake. One of the sources of enriching the human diet with these nutrients can be flaxseed flour. The reason for the rare use of flaxseed flour in baking is the change in the taste and aroma of the finished product. Research to determine the method of adding flaxseed flour was carried out in the laboratory of baking and confectionery production of Vyatka State Technical University. Flax flour was added to bread in the form of sourdough mixed with rye flour, dough from flax flour, and dough from a mixture of flax and rye flour, as well as in dry form into the dough. Organoleptic and physico-chemical quality indicators of semi-finished and finished products were studied. Generally accepted research methods were used in the research. As a result, it has been found that flaxseed flour changes the taste and smell of rye bread to the least extent when it is fermented with yeast in a dough. Fermenting flaxseed flour together with rye flour does not result in the loss of flaxseed taste and aroma. It has been proved that preparing dough using flaxseed flour requires more water than preparing sourdough and dough from rye flour. Sourdough with the addition of flaxseed flour gains acidity faster. Bread with the addition of flaxseed flour in the form of dough is practically no different from the control variant. The crumb of such bread has an acidity of 9.0 degrees, moisture content of 49.9% and porosity of 49%. The tasting has shown that bread with the addition of flax dough among the studied samples scored the highest number of points and was as close as possible to the control version.

Due to its unique structure, chemical composition, physical and mechanical properties, grapes are one of the most valuable types of plant raw materials, the processing of which produces by-products: grape pomace, grape seeds, grape bunches, yeast sediments. The amount of grape pomace is about 20-25% of the total mass; if not used, this leads to an increase in production costs. Traditionally, grape pomace has been used as fertilizer or animal feed, but only the polyphenol content has been studied. Grape pomace is a complex natural composition of various components: skins, stems, grape seeds (seeds). Red wine marc is a by-product of fermentation, while white and rosé wine marc is removed before alcoholic fermentation, leaving the fermentable sugars in the marc. They contain organic acids, vitamins, microelements, and grape oil extracted from the seeds. The industry is expected to function as a natural ecosystem, with waste from one industry becoming the raw material for another. In order to rationally use natural raw materials, the main emphasis is on the development and implementation of new competitive high-tech safe technologies, as well as the search for new sources of biologically active substances from waste from food enterprises. The purpose of the research is to study the quality indicators of grape marc obtained using the white and red methods of processing grapes as raw materials for the production of functional soft drinks. It has been established that grape pomace is represented mainly by skins (84.8-87%). The main acids in grape pomace are tartaric («Firstborn of Magarach», «Cabernet Sauvignon») and malic. The main cation is potassium («Rkatsiteli»). The rich chemical composition provides enormous potential for the use of secondary grape processing products for the production of functional soft drinks.

The article presents the results of the influence of high hydrostatic pressure (HHP) on some functional properties of pea protein isolate. HHP was combined with different pH conditions to investigate the cumulative effect of HHP-based food processing conditions on the functional properties of pea protein isolate. Pea protein isolate solutions prepared at different pH conditions (5.0, 6.0, and 7.0) were subjected to HHP treatment at 200, 400, and 600 mPa at 18 °C for 5 min. The water resisting capacity (WRC), solubility and emulsifying properties of pea isolate samples were determined. It was found that treatment with NPP increased the VUS of pea protein isolates by 1.5 times. The greatest increase was observed in samples treated with a pressure of 400 mPa, at pH=7. An increase in solubility was found with an increase in pH from 6 to 7 when using a pressure of 400 and 600 mPa, however, for a sample of soybean isolate at pH 7 and a pressure of 200 mPa, on the contrary, a decrease in solubility was recorded. It has been shown that the effect of NPP on the emulsifying properties of pea protein depends on the processing conditions. In some cases, HPP can improve emulsifying properties, providing more stable emulsions. However, increasing exposure to high pressure up to 600 mPa leads to a decrease in emulsifying stability. The optimal parameters for using NPP for pea isolate proteins are a pH in the range of 6-7, and a pressure of 400 mPa.

The article describes the results of work on the creation of low-growing pear varieties with a red outer color of a fruit, adapted to the conditions of the foothill zone of the North-Western Caucasus (the Republic of Adygea). Many years of studying and selection pear variety were carried out by employees of the Maikop Experimental Station, a branch of VIR. The breeding task was to combine a number of valuable traits in the genotype of new varieties: small size of trees, early onset of fruiting, high yield, bright color of fruits, their good taste and late ripening, as well as resistance to fungal diseases. A comprehensive assessment of the source material was carried out and genotypes that were promising for breeding were identified. To obtain weak-growing hybrids, the weak-growing varieties of Obilnaya, Jacques Tellier, Triomphe de Vienne, Amiral Gervais, De ľAssomption and others were used. The variety of Max Red Bartlett (Max Red Bartlett, Williams Red) and its descendants became the donors of the red outer color of the fruit. To improve the quality of fruits and late ripening, high-quality varieties of Abbé Fetel, Doyenné d'Hiver, Martin and others were used. As a result of simple and multi-stage crossings, a hybrid fund of more than 100 samples was created, from which genotypes were isolated that had a complex of positive economically valuable traits that were promising for production and selection. Their brief characteristics are given.

The article highlights issues of breeding work at Gorsk State Agrarian University in 2022. Obtaining productive potato varieties that resistant to various pathogens in the conditions of the mountain foothills of the North Caucasus is the goal of the research. The main objectives are to identify dominant characteristics of the studied varieties for their further use as parent forms, to evaluate hybrid offspring based on the main economically valuable characteristics, to select the most valuable genotypes according to variety models for a given region (6). In the collection nursery parental pairs were identified for further use in the breeding process. The studies were carried out on mountain meadow and leached chernozems of the North Ossetia-Alania. The experiments were carried out according to the methods of selection and seed production developed by VIR, VIZR and VNIKH named after. A.G. Lorja. In various nurseries of the breeding process promising hybrid offspring were identified. In the maternal nursery more than 6.5 thousand seeds were obtained as a result of backcrossings in 7 combinations. In the nursery of first-year seedlings 15% of genotypes were rejected according to morphological characteristics. During harvesting 42% of genotypes were rejected and the selection rate was 58%. In the nursery of second-year seedlings the average selection among planted genotypes averaged 79.2%. In the nursery of seedlings of the third year hybrids of four combinations were tested, 3 of which were rejected, only 133 combinations of offspring were obtained, and the selection rate was 11.1%. The isolated hybrid progenies, namely, 12.64/368, 12.40/1 and 12.64/394 with a yield of 51.7 t/ha, 48.7 t/ha and 48.1 t/ha, and marketability of 82.3%, 80.0% and 84 .0% will accordingly be transferred to a breeding nursery for further research and submission to the State Crop Testing Site of the Russian Federation.

The experiment showed that in the risky farming zone where the experiment was carried out, the introduction of mineral nutrition into southern chernozem significantly influenced the content of nutrients in the soil. Experimental studies were carried out in 2018-2021 on the southern chernozem of the Volgograd region, on the fields of the «Eliseev A.N.» peasant farm, located in the Mikhailovsky district. The varieties of spring durum wheat Donskaya Elegiya, Krasnokutka 13 and winter durum wheat Aksinit and Agat Donskoy were compared with the addition of the calculated amount of mineral nutrition for given yield levels. The experience showed that in variants without the addition of mineral nutrition, it accumulated in the early spring (this was the maximum accumulation) from 5.02 (Don Elegy) to 5.07 (Aksinit) mg per 100 g of soil. The application of N₁₄₇P₅K₉₀ to all varieties was marked by the maximum accumulation of the amount of nitrate nitrogen, and it varied between varieties from 7.01 (Aksinit variety) to 7.57 (Krasnokutka 13 variety) mg per 100 g of soil. By the end of the growing season the least amount of nitrate nitrogen was retained on the Aksinit variety – 4.11 mg per 100 g of soil. While the Krasnokutka 13 variety retained the level of 4.71 mg per 100 g of soil. A similar dependence was observed for the accumulation and consumption of mobile phosphorus. As a result, in varieties without the use of mineral nutrition, the yield ranged from 1.34 t/ha (Krasnokutka 13) to 3.41 t/ha (Aksinit). The maximum yield values were obtained from the application of N₇₄Р₂₇К₄₅ and it ranged from 2.41 t/ha (variety Krasnokutka 13) to 4.02 t/ha (variety Aksinit).

The classic selection of plants for landscaping the urban environment is a rather labor-intensive process involving the use of a large number of reference materials, atlases and plant catalogs. It is necessary to consider various characteristics of plants, taking into account their decorativeness, mutual compatibility, survival in the natural conditions of each region, etc. The purpose of the research was developing a polytomous key and creating it using a modern computer program to simplify the selection of plants according to decorative, phenotypic and phenological characteristics for landscaping cities in the southern Russia. The method of compiling a polytomous key was used as a way to identify plants by several leading characteristics, when the original groups were simultaneously divided into several smaller ones. The life forms, size, habitus of plants, characteristics of the trunk and crown, characteristics of flowering and fruiting, as well as environmental requirements were taken into account. On the basis of the research results the assortment of ornamental plants in large nurseries of the Krasnodar Territory and the Republic of Adygea, a list of plant names was compiled and their characteristics were encoded using a polytomous key. The key consisted of 8 sections, thanks to which it was possible to give the most complete description of the plant according to 36 parameters. The resulting database received state registration certificate No. 2023621905. The base and operation of the polytomous key are like a computer program. The functioning of the program has been successfully tested. The created program greatly simplifies the work of choosing an assortment of plants for landscaping, reducing it to a few minutes.

Soil rating is a comparative characteristic of the quality of arable land and other areas, assessed in points. It is carried out on the basis of special soil surveys, taking into account the supply of nutrients and other factors that determine the level of natural fertility. Soil rating is a necessary starting point for the economic assessment of land, determining the standard price and creating a land cadastre. The article presents the results of a comprehensive study aimed at determining the qualitative characteristics of the soil cover of the Republic of Adygea. As a result of determining the quality score, it is possible to predict how much agricultural land will be harvested in the future, as well as to determine the sowing plan for this area for the year. Determining the soil quality score is also important when resolving issues such as regulation of land relations, timely adoption of measures to improve land plots that are unsatisfactory in terms of indicators. Establishing a quality score allows for high-quality implementation of agrotechnical, hydraulic and chemical measures in those areas that are considered the worst as a result of determining soil quality. The groups of soils established during rating, which are quantitatively characterized by certain natural characteristics, form the information basis for the economic assessment of land, the data of which are important for the rational use of selected agricultural production groups, taking into account their natural characteristics. Based on the conducted research, recommendations are offered for using the obtained assessment results for the cultivation of various agricultural crops. The importance of using the results of soil assessment to improve the efficiency of land use, improve agricultural production and ensure sustainable development of the region has been emphasized.

The influence of the traditional method of storing potato varieties, namely Gala, Colombo, Red Scarlett, grown in the Southern Federal District, on its biotechnological potential was studied. It was determined that in the tubers of the Gala varieties the dry matter content was – 25.20%, in Red Scarlett – 22.6%, the ratio of protein and starch in the tubers of the Gala varieties (1: 11.1) and Red Scarlett (1: 10.7), which indicated their good technological properties. The Colomba variety had a dry matter content below 20%, and the protein to starch ratio also had a lower value (1: 9.3). Protein losses during storage amounted to, in varieties of , in%, Gala – 7.5; Colomba – 9.2; Red Scarlett – 4.9; starch loss – 10.9; 8.8; 17.8 respectively. The mass fraction of reducing sugars decreased in all potato varieties, in%: Gala – by 39.4; Colomba – at 67.7; Red Scarlett – at 55.0. The loss of vitamin C during storage was, in varietiesof, in% Gala – 23.8; Colomba – 26.8; Red Scarlett – 33.3. It was determined that potato tubers contained a level of nitrates that was acceptable for food raw materials and food products, while their content decreases during storage. Nitrate losses were, in varieties, in%, of Gala 57.1; Colomba 49.0; Red Scarlett 54.6. Changes in the physical and chemical properties of potatoes after storage indicate the preservation of the biotechnological potential of the raw material and the possibility of its use in public catering establishments. The Gala variety of potatoes is universal for processing in catering establishments; it is suitable for use in dishes (boiled, fried, baked), preparing multifunctional semi-finished products (for salads, soups), chips, crispy potatoes, etc.
