Carotenoids are widely used and demanded as natural dyes in food technologies due to their biologically active properties. Due to antioxidant properties, carotenoids are widely used for the prevention and treatment of various human diseases, including oncological, cardiovascular, diabetes, etc. In addition, carotenoids are the main sources of vitamin A, which is not produced by the human body, but has a great influence on eye-sight, growth, development and reproductive function of the body. The purpose of the research is to analyze scientific and technical literature to determine the physiological function of carotenoids and the possibilities of their use in food technologies. Carotenoids enter the human body with food and their presence in sufficient quantities in the human diet ensures the normal functioning of the body. The issues of using lycopine and beta-carotene as food dyes and food additives in food technologies have been considered, as well as biologically active components when creating food products, including specialized, functional and personalized ones.

The analysis of scientific information has shown that, due to their biological properties, carotenoids perform an important physiological function in a person’s life. The expansion of the area of their use determines the increase in the production of carotenoids and food using them. In accordance with this, studies in the field of improving existing technologies for obtaining carotenoids and expanding the raw material base are relevant, including the use of secondary resources of processing carotene -containing raw materials.

The most important factors determining human health, as well as the duration and quality of life, are lifestyle and nutrition. Improper nutrition, frequent stress cause different diseases. In this regard, over the past decades, the need for micronutrients and other physiologically necessary substances has increased. Currently, functional nutrition is becoming increasingly important, thanks to which the human body, along with food, receives necessary proteins, vitamins, flavonoids, macroand microelements, and other biologically active substances. Functional foods are beneficial to human health due to their high content of functional ingredients. They help to increase the resistance to various diseases and to normalize many physiological processes in the human body.

The use of non-traditional and little-known raw materials creates an opportunity to solve the problem of producing high-quality functional food products. One of the types of such vegetable raw materials are hemp seeds, which are characterized by a high content of biologically active substances. This creates prospects for the use of hemp seeds in the production of functional products.

The article presents the developed functional confectionery products – dark and milk chocolates with hemp seeds. The optimal ratio of filling components for chocolates has been selected. The effect of the concentration of ingredients on the quality of bitter and milk chocolate has been studied. Recipes and technologies for dark and milk chocolates with hemp seed filling have been developed.

The carried out theoretical and experimental studies has confirmed the effectiveness of the use of hemp seeds and allowed the development of new recipes for chocolates. The product launch contributes to the expansion of the range of functional confectionery products.

The article presents data on the study of the influence of fermentation conditions on the content of biologically active substances of the phenolic complex in young red wines.

Red wines, due to the high content of phenolic substances in them, have P-vitamin activity, antiglycemic, antihepatoxic and antimutagenic effects, as well as antimicrobial and other types of biological activity. Many of the phenolic substances act as natural antioxidants, have a radical-cleansing ability, and help reduce blood cholesterol levels. Thanks to these properties, red wines contribute to the prevention of many diseases and correct the antioxidant status of a person.

The objects of the research are wine materials obtained from grapes of the Moldova variety by the method of carbon dioxide maceration, with a process duration of 4 days or 7 days. In the second case, additional introduction of carbon dioxide of exogenous origin hasa been used. As a control one, wine material obtained by traditional technology has been used, as a result of must fermentation on pulp with a floating cap.

The influence of fermentation conditions on the total content of monomeric and polymeric phenolic compounds, as well as on the mass concentration of individual phenolic acids and flavonoids, has been studied.

It has been established that an increase in the duration of maceration of a bunch of grapes up to 7 days, as well as the additional introduction of CO₂ of exogenous origin, have contributed to the intensification of extraction processes and led to a natural increase in the concentration of substances of the phenolic complex.

Thus, the possibility of using carbon dioxide maceration, which ensures the optimal accumulation of substances of the phenolic complex, has been established for the production of young red table wines, especially when processing high-acid grape varieties with a high content of anthocyanins and tannin. Carrying out carbon dioxide maceration of whole bunches of grapes under conditions of anaerobiosis has contributed to the preservation of biologically active substances in wine, including vitamins, stilbenes, phenolcarboxylic acids.

The research is devoted to the creation of a new recipe and technological solutions for the production of gluten-free gingerbread products for people who need dietary nutrition. Our studies were carried out in accordance with GOST 15810-2014 «Confectionery products. Gingerbread products. General specifications». Based on marketing research, it has been established that nowadays production of gluten-free confectionery products, including gingerbread ones, is underdeveloped in the region. The following samples of gingerbread products are considered in the research: the control one – 100% wheat flour; No. 1 – 50% rice and 50% corn flour; No. 2 – 50% corn and 50% pumpkin flour. As a result of the experiments, sample No. 1 with the best organoleptic characteristics has been selected. The gluten level in the gingerbread product under study was calculated, and it amounted to 7 mg/kg, which according to TR CU 027/2012 was lower than the normalized value (20 mg/kg). Therefore, this product belongs to the «gluten free» product group. It has been established that due to the high water absorption capacity, the introduction of mixture No. 1 into the food industry is relevant, since there is a greater rise in the dough during baking and less thickening of starch grains. As a result of our calculations of the chemical composition of this product, it has been found that through the use of an alternative type of raw material, it is possible to design products with various contents of food and biologically active substances, including a vitamin–mineral complex, which are not inferior in their characteristics to traditional products made from wheat flour. Thus, the studies conducted have shown that the use of non-traditional types of raw materials (rice and corn flour) allows one to make gluten-free products with high quality indicators, including organoleptic, structural-mechanical properties and enriched in nutritional value.

Increase in animal protein resources is of great importance on a global scale. Proteins of animal origin provide the human body with basic macroand micronutrients and support normal human life and activities. Poultry meat occupies a significant proportion in the state program of production and sale of animal proteins. From year to year, the growth and consumption of poultry meat (30...35 %) is constantly increasing. Mechanically deboned poultry meat is characterized by less technological potential and is in need of increase its functional and technological properties in the formation of food systems with specified properties.

The article shows the possibility of expanding the assortment of meat chopped semi-finished products (cutlets) of functional purpose using a compositional mixture in a recipe that helps to increase biological and nutritional value.

The purpose of the research is to develop the recipe and technology of mechanically deboned poultry meat semi-finished products (cutlets) of functional purpose using non-traditional raw materials, namely compositional mixture (CM).

The qualitative and quantitative composition of the compositional mixture for cutlets of functional purpose from mechanically deboned poultry meat has been substantiated and selected.

The influence of the dosage of the compositional mixture consisting of a solid Adygh cheese

«Mate» (powder), oatmeal and garlic powder, on the consumer properties of mechanically deboned poultry meat has been investigated. The quality indicators (organoleptic and physico-chemical ones) cutlets of functional purposes have been investigated.

The recipe and technology of functional cutlets has been developed where wheat bread is replaced completely (100%) with a compositional mixture and coating with oatmeal flour. This technology has shown the best quality indicators.

Protective forest strips are the basis of the environmental frame on sparsely wooded areas. To create such highly productive objects, the selection of the corresponding gene pool is required. Plus trees the representatives of this gene pool. The aim of the research is to develop criteria for highlighting plus trees for protective forestry, focused on the creation of plantings, the main parameter of which is the working height. 16 trial areas of cherry oak (Quércus róbur L.), black locust (Robinia Pseudoacia L.), green ash (Fraxinus lanceolata B.), European ash (Fraxinus excelsior L.), thorney locust (Gleditschia triacanthos L.), walnut (Juglans regia L.) have been laid out. A continuous recalculation of heights in 100–142 individuals have been recalculated on each trial area and their statistical indicators have been determined. The height of the trees had a normal or close to it statistical distribution at the studied objects. Data processing was carried out using the Stadia 8.0/Prof licensed program for Windows. The method of selecting plus trees has been proposed, the height of which should exceed the average one by 25% or more. A comparison of the proposed and well -known method has revealed that the proposed one can increase the breeding differential with instrumental selection by 48,25–53,78%, and with eye-instrumental selection by 31,15–41,39%. Criteria for trees of various selection categories have been developed. Due to different conditions, it is recommended to highlight plus trees separately in the extreme and mid-protective forest strips. With breeding inventory, it is also necessary to take into account the sanitary condition of the trees.

Over the past years highly effective phytopreparations with antibacterial activity have been created in Russia. Macleaya x kevensis Turill, which is a hybrid between heart-shaped Macleaya (Macleaya cordata) and small-fruited Macleaya (Macleaya microcarpa), can serve as a raw material for their production. To provide the pharmaceutical industry with this type of raw material in the conditions of the North Caucasian branch of VILAR, plantations of this crop have been created and research is being carried out to create a zonal technology for its cultivation. The basis of cultivatiov is the exogenous regulation of the processes of growth, development and bioproductivity of the plant organism through the use of organomineral and microfertilizers. In 2019–2022 experiments on testing humic fertilizers (Potassium Humate, Lignohumate) and their complexes with silicon-containing microfertilizer Siliplant were carried out on the Macleaya plantation. Treatments with these preparations were carried out: in the 1st year of the growing season – at the beginning of regrowth and after 30 days, in the 2nd and 3rd years of the growing season – at the beginning of the growing season and after the first harvesting of raw materials for growing plants. As a result of the tests, an increase in the growth and development of Macleaya plants was observed. The activation of growth processes contributed to an increase in crop yield in the first year with a single cut by 0.18–0.19 t/ha (17–18%), in the 2 and 3 years of the growing season by the sum of two cuts by 1.50–1.76 t/ha (20–24%) and the collection of alkaloids per hectare by 21–27%.

Sugar sorghum is mainly used for green fodder, haylage and silage. The accumulation of sugars occurs throughout the growing season. The relevance of the study is to identify a high-yielding variety or hybrid of sugar sorghum containing a large amount of sugars, which are later used for the manufacture of feed. The purpose of the study: to assess the impact of agrotechnical techniques on the feed evaluation of sugar sorghum. Tasks: to consider the dynamics of the accumulation of sugars in the stems of sugar sorghum; to calculate the yield of sugar from the stems of sugar sorghum; to determine the biochemical composition and gross energy of the green mass of sugar sorghum. The experience is three-factor in four-fold repetition. The experimental fi were located in the LLC “Kuznetsovskaya” Agricultural Complex of the Ilovlinsky district. The research period is 2009...2015. The research provided for the study of the nutritional value of sugar sorghum (crude protein, fat, protein, sugar, BEV). When determining the dynamics of the accumulation of sugar sorghum, the best indicator was on the variant of the joint use of the biostimulator of growth Lignohumate and mineral fertilizer on the hybrid Slavyansk homestead. For dump tillage, the average accumulation of sugars on this hybrid varied from 5.5 to 18.4% of dry matter, for zero tillage – 6.1 to 18.65%. The amount of sugar yield was influenced by the yield and concentration of sugars in the stems. The largest content was on the hybrid Slavic household. For dump and zero tillage, the best option was against the background of the combined use of a growth biostimulator and mineral fertilizer, amounting to 11.3 and 13.3 t/ha, respectively. When further determining the biochemical composition of sorghum, the best indicators for the content of crude protein, fat, fi  and ash were on the Debut variety. On the Slavic fi   VS variety and the Slavic homestead hybrid, these indicators had average values. The amount of nitrogen-free extractive substances contained more on the Slavic homestead hybrid, averaging 64.9%.

In agrotechnologies postcut crops of intermediate cultures are placed after harvesting annual grasses for green mass, and stubble crops after harvesting early grain crops. Annual herbs at the April sowing dates reach mowing maturity and are harvested for green mass in the third decade of June – the first decade of July. However, after harvesting the main crop of the crop rotation, there are still about 70–90 days left until the end of the growing season, which is quite enough to obtain a full-fledged harvest in the hay crops, and thereby increase the index of arable land use [1; 6]. In this regard in 2020–2022 in the foothill zone of the Kabardino-Balkarian Republic (the Baksansky district), the scientific research was carried out on the irrigated Ciscaucasian chernozems (according to B.A. Dospekhov “Methodology of field experience”) in order to study the elements of improving the technology of growing corn in hay crops, providing a reduction in energy costs and optimization of the main parameters of soil fertility. Recently, agricultural production has been operating in the conditions of a resource deficit and an increasingly complex structure of economic relations and an ever-increasing problem of soil and water conservation. The dominance of economic mechanisms fundamentally changes many generally accepted ideas and approaches in the field of agricultural land use. The overall objective is to maximize crop production per unit of input. As a result of the research, it has been found that the cultivation of corn for grain by cutting, after winter rapeseed by chisel processing to a depth of 28–30 cm and the application of fertilizers at a dose of N₁₂₀P₉₀, contributes to the stabilization of the agrophysical properties of the soil and the optimization of the energy balance

Corn is one of the main crops of modern world agriculture, versatile use and high yield, which can largely solve the problems of food security. Various types of weeds can cause significant losses of its yield, which can reach 50% or more, which makes it necessary to provide for protective measures against them in technological schemes of corn cultivation. In corn cultivation technologies, the weed control system is of great importance, since corn grows very slowly at the beginning of the growing season. The purpose of the research is to study the influence of various agrotechnical techniques on the number and variety of weeds in sugar corn crops in the conditions of the Lower Volga region. The tasks of the research are to determine the number and species composition of weeds during the growing season of sweet corn; to determine the effect of herbicides on weeds in sugar corn crops. The experiments were carried out in LLC “Kuznetsovskaya” agricultural company of the Ilovlinsky district of the Volgograd region and in S.A. Popov’s farm of the Chernoyarsky district of the Astrakhan region. The research period is 2009...2015. The contamination was determined by quantitative and weight method on an area of 1 m². According to all variants of the experiment, the contamination was attributed to a mixed juvenile and long-term type, while no stable patterns were observed in changing the ratios between these components.

As a result, it has been revealed that the number of weeds in LLC “Kuznetsovskaya” of the Ilovlinsky district of the Volgograd region varied from 6 to 17 pcs./m². For dump tillage, this indicator varied from 6 to 11 pcs./m², for zero tillage – 13...17 pcs./m². In S.A. Popov’s farm of the Chernoyarsky district of the Astrakhan region, the number of weeds for dump tillage was 4...9 pcs./m², depending on the influence of agrotechnical reception, for zero tillage contained from 10 to 17 pcs./ m².

In the agricultural technology of sunflower cultivation, plant density in crops is one of the main conditions that determine its further productivity [5]. The optimal sowing density of sunflower can vary widely and depend on various factors, such as the varietal characteristics of plant, the soil-climatic zone of its cultivation, specific weather conditions and, above all, the moisture supply of plants, especially in the critical phases of sunflower development (flowering and grain filling) [ 8]. It has been proved that the optimal plant density in sunflower crops is such that not only normal growth processes and development of each plant are ensured, but the maximum possible productivity per unit of sown area is also formed. In this regard, in 2018–2020, in the flat zone on the leached chernozems of LLC «Zarya» of the Shovgenovsky district of the Republic of Adygea, studies were carried out (according to B.A. Dospekhov «Methodology of field experience») in order to study the reaction of new promising sunflower hybrids (Gorstar, Natali, Iren, selection of Federal State Budgetary Scientific Institution «FSC «VNIIMK named after V.S. Pustovoit», Krasnodar) to change the number of plants per hectare. As a result of the research, the degree of influence of the studied factor on the formation of productive qualities of the studied sunflower hybrids has been established

– the diameter of the anthode, the number of oil seeds in it, the mass of achenes from one anthode, the weight of 1000 achenes, the fulfillment of achenes, seed yield, total collection of oil from one hectare area). The studies have shown that the maximum seed yield has been achieved in the hybrids Gorstar and Iren, formed on the second variant (50 thousand pieces/ha). In the Natalie hybrid, the maximum yield was recorded in the variant with a plant density of 60 thousand pieces/ha. From this, it should be noted that with the option of 50 thousand pieces/ha, the Natali hybrid turned out to be 0.62–0.61 t/ha less productive than the Gorstar hybrid and 0.52–0.56 t/ha than the Irene hybrid.

The studies were carried out on the equipment of the «Expert» Common Use Center of FSBEI HE «MSTU».
