Currently, there is an increase in the volume of rapeseed processing, which leads to a natural increase in the production of by-products such as rapeseed lecithin. One of the indicators of the quality of lecithins, which determines the content of physiologically valuable components – phospholipids is the weight fraction of substances insoluble in acetone. The aim of the study is to develop an integrated system for metrological support of an instrumental method for determining the weight fraction of substances insoluble in acetone, contained in rapeseed lecithins, using the pulse NMR method. The main element of this system is standard imitating samples with known metrological values of the mass fraction of substances insoluble in acetone. As a result of the conducted studies of NMR characteristics of natural samples of rapeseed lecithins with different mass fractions of substances insoluble in acetone, the optimal parameters of NM relaxation characteristics of standard imitating samples have been determined. It has been shown that three substances are required to create standard imitating samples, while to simulate the protons contained in the oil phase of rapeseed lecithins two substances are required using spin-spin relaxation time from 77 to 110 ms and a spin-spin relaxation time from 23 to 28 ms, and to imitate phospholipid protons – a substance with a spin-spin relaxation time from 2 to 6 ms is required. On the basis of the study of NMR characteristics of protons contained in samples of chemically inert organic silicon liquids and natural latex, a composition of 6 standard samples-imitators of the mass fraction of substances insoluble in acetone contained in rapeseed lecithins, and a procedure for their use for NMR calibration analyzer AMV-1006 M have been developed.

The article studies the processes of structure formation of baked dough pieces using wheat and hop starters and changes in the properties of finished products and semi-finished products depending on the baking methods. A whole complex of physical, chemical and biochemical processes takes place in the dough piece during baking under the influence of heat and moisture, which causes considerable changes in the bread dough. These processes cause changes in the baked dough piece, that cause turning the dough into bread. Duration and intensity of the processes occurring on the surface and in the inner layers of the dough piece during baking depend on the temperature. Therefore, creation of optimal modes of heating the baked dough piece at various stages allows you to get products of the required quality. To simulate the processes of crumb formation, changes in temperature inside the dough piece of baking, and specific volume over time with different methods of dough and baking, regression models were used, that take into account the influence of qualitative factors. Each qualitative factor having two grades was replaced by one binary variable. The solution of a multicriteria optimization problem showed that the studied indicators reach the optimal values when baking in an air-o-steam and preparing a dough using hop starter.

Existing technological schemes of lime-carbon dioxide purification of diffusion juice include lime treatment (defecation) and two-stage treatment with carbon dioxide (saturation) with sediment separation. Improving cleaning methods aimed at increasing its efficiency is an urgent task. Lime-carbon dioxide purification of the concentrated sugar-containing solution before boiling allows to improve the quality of sugar, reducing the syrup color and increasing its natural alkalinity. The proposed purification scheme, which includes overcarbonation to low syrup pH values (8 and below), its mixing with carbonated syrup and adding activated suspension of II saturation sediment, makes it possible to obtain a purified solution with an increased effect of adsorption purification, with a significantly low content of high-molecular compounds and their calcium salts. The results of the study of various schemes for the purification of syrups in a laboratory setup have been presented. A method for purification of concentrated sugar-containing solutions, protected by a patent of the Russian Federation for the invention, has been developed, which provides for the reduction in the consumption of calcium hydroxide by 0,10–0,12% of CaO by weight of the product or by 0,04% by weight of beet.

Experimental data on the kinetics of drying of raw brewer’s grains from the Maykop brewery for two temperature regimes of 60°C and 55°C are presented. The dry matter content is 12,7%. The drying agent speed is 4,5 m/s. The purpose is to determine the content of free and attached moisture in brewer’s grains obtained as a waste in the production of beer using classical technology. Analysis of the drying curves and drying rate curves has shown that free moisture is removed when the moisture content changes from the initial 687,4% to 360%; with a further decrease in the moisture content, the attached moisture is removed. A moisture content of 360% is assumed to be at the interface between the first and second drying periods. The average free moisture content is 47%, that of the attached one is 53%. A significant amount of the attached moisture indicates insufficient destruction of the cellular structure of the material.

A non-smoking, nicotine-containing, non-tobacco product is new to Russia. There are no normative legal documents regulating circulation, production, certification, control methods and ingredient composition. The composition of the product is not controlled. The absence of state regulation, technical requirements and regulatory documents for nontobacco nicotine-containing products, control methods and methods for its identification is a serious problem today, and the solution of the listed problems is extremely important and urgent. This situation has led to the appearance of a large number of products produced by semihandicraft methods. Technical conditions for their production are the property of a manufacturer, which allows unscrupulous manufacturers to manufacture a product that often represents a real threat to the health of consumers. The research began in 2018 in the Laboratory of technology for the manufacture of tobacco and tobacco products and aimed at solving the following problems: – monitoring of the Russian market of non-smoking nicotine-containing products for oral consumption; – research of consumer characteristics of brands of this type of products; – obtaining experimental data for an objective assessment of the toxic load of the test samples. The work was carried out according to the program developed in the laboratory using the following methods: – visual inspection (establishes the appearance of the consumer packaging and the labels on the packaging); – organoleptic and tasting assessment (establish consumer characteristics of the product); – establishment of individual characteristics (presence or absence of tobacco); – determination of physical, chemical and toxic indicators of the product: humidity, fractional composition, nicotine content.

Non-smoking products for oral consumption are a growing segment of the nicotinecontaining products market and, therefore, the study of the component composition and toxicological load during its consumption is an urgent task. The toxic components of nicotine-containing products are the subject of research in scientific laboratories and are carried out by various methods. Studies have been monitored for potential toxicity determinations of tobacco and non-tobacco smokeless products. The article presents the results of monitoring methods for determining toxic components that determine the risk of nonsmoking products, carried out at the Federal State Budgetary Scientific Institution ARSRCTTP. As a result of the research, methods for the quantitative determination of nicotine content have been determined and the method for the determination of tobacco-specific nitrosamines (TSNA) using high-performance liquid chromatography in the product under study has been validated.

Technologies for obtaining expanded tobacco have been developed, which make it possible to increase the volume of tobacco leaves up to 50% and reduce the consumption of tobacco raw materials in the manufacture of smoking articles by up to 30%. However, they have a number of disadvantages, the main one being a decrease in the tasting evaluation of raw materials. The subject of the research is to determine the effect of microwave radiation when processing freshly harvested tobacco leaves on improving the qualitative and quantitative indicators of tobacco raw materials. The object of the research is freshly harvested leaves of three botanical varieties of tobacco grown at the experimental site of the Federal State Budgetary Scientific Institution «All-Russian Research Institute of tobacco, makhorka and tobacco products», harvested in the condition of technical maturity. The purpose of the research is to study the effect of microwave- radiation treatment of tobacco leaves during their post-harvest processing on the possibility of obtaining expanded tobacco and on the qualitative and quantitative composition of raw tobacco. The following has been established: the obtained raw tobacco in terms of dimensional characteristics is similar to expanded tobacco obtained under factory conditions; carbohydrate-protein ratio (Shmuk’s number) in comparison with the control on has increased 2,5–4,5 times, and the nicotine content has decreased 1,3–1,4 times; the conventional consumption of raw tobacco for the manufacture of cigarettes is reduced by 8 ... 17% in comparison with the control one, depending on the drying technology. The results of the studies have revealed the positive effect of microwave radiation when processing freshly harvested tobacco leaves on the improvement of the qualitative and quantitative indicators of raw tobacco.

The article presents experimental data on the assessment of the rheological properties of dough from new types of flour, formed on the basis of cumulative curves using the Mixolab device. The data of mixolabograms and radial diagrams (Mixolab profiler) made it possible to reveal the existing differences in the parameters of the rheological profile and Mixolab indices. The object of the study is composite mixtures of gluten-free flours: No. 1 is 50% of pumpkin and 50% of corn flour, No. 2 is 50% of linseed and 50% of corn flour, No. 3 – 50% of rice and 50% of corn flour, No. 4 – 75% of linseed and 25% of corn flour, No. 5 is 30% of linseed and 70% of rice flour. The use of composite mixtures is promising due to high oven rise and low starch thickening because of its high water absorption capacity (WAC). In addition, there is certain economic efficiency, since it is possible to produce more dough at a lower cost.

The aim of the research is to develop the requirements for the consumer properties of salted fish products from fish of the South of Russia based on an analysis of consumer preferences obtained as a result of a sociological survey and determining the possibility of adjusting the color of salted fish products in accordance with the developed requirements. The objectives of the study are: development of requirements for the consumer properties of salted fish products from the fish of the South of Russia based on the analysis of consumer preferences obtained as a result of a sociological survey; selection of food colors for processing salted fish; determination of color characteristics (color formula) of salted fish colored with food dyes using the RGB color system using the FastColorPick computer program. The objects of the study are fish from the South of Russia: pilengas (Mugil so-iuy Basilewsky), silver carp (Hypophtalmichtys molitrix Val.), Common carp (Caprinus carpio), golgfish (Carassius auratus gibelio). As a result of the studies, it has been found that consumers prefer the color of salted fish products, which is similar to the color of the muscle tissue of salmonids. In order to obtain the desired color of salted fish products from the South of Russia, it is possible to color them with food dyes. An effect similar in color to that of salmon fish species has been obtained by staining the muscle tissue of the studied fish species with a 0,3% solution of E160c wig dye and 0,1% solution of neolin DR dye. As a result of treating fish with a solution of E120 carmine dye, a shade is formed that is not characteristic of the natural color of salmon fish.

The results of many years of physiological research, which have been carried out in the Laboratory of plant physiology and biochemistry of the Federal Research Center «Subtropical Scientific Center of the Russian Academy of Sciences» (earlier – VNIITSISK) have been presented. The objects of the research are peach leaves of the varieties of Redhaven (control), Nicholas I (Collins clone), Larisa, Krasnaya Zarya (Redhaven clone), Comanche, Sunbeam, Spring Call (Springold clone), Summerset. It has been found that the amount of water deficit does not exceed 12,1–14,2%, and the water content of the leaf blades ranges on average from 55,2% to 70% in the varieties of Redhaven, Comanche, Summerset, Larisa. As stressful situations intensify (drought, lack of moisture in plants, high air temperature and humidity) in the subtropical zone, the Comanche, Vesennyy Prizyk and Summerset varieties show a decrease in the synthesis of a, b, chlorophyll and in the most resistant varieties of Redhaven, Larisa, Krasnaya Zarya, Sunbeam and Nicholas I show its decrease. A high content of carotenoids is up to 0,52–0,65 units.

The results of the studies of different doses of dressings on the yield and nutritional value of green mass of clover for two years use are presented. The experiment was carried out in April 2017 on No. 3 scientific field of the FSBSI «Adyghе Research Institute of Agriculture using B.A. Dospekhov’s method. The experiment was repeated 4 times, the arrangement of repetitions and variants was systematic. The object of the research was Abadzekhsky local red clover variety. In the research a moldboard method of tillage was used to a depth of 20–22 cm. Analysis of the data obtained showed that the maximum yield of green mass of clover, both I and II, was obtained in the variant with an increased background of mineral nutrition and amounted to 15,1 t/ha; 25,1 t/ha. The yield of clover hay in the first and second years of life with the application of the highest dose of nitrogen fertilizers (N45) was 4,8 t/ha and 7,2 t/ha. Complete zootechnical analysis of the nutritional value of the green mass of red clover I g. showed that 1 kg of dry feed contained 0,75–0,80 g/kg of feed units. The provision of digestible protein in the green mass of clover increased with an increase in the background of mineral nutrition 77,7–98,8 g/kg. The content of metabolizable energy in 1 kg of dry food was 8,7–9,3 MJ. The fodder value of green mass of clover of II y. showed that the content of digestible protein varied in the options within 74,0–94,1 g. The content of feed units in 1 kg of dry feed was 0,75–0,86 g, metabolic energy 9,6–10,3 mJ. The content of digestible protein, feed units and metabolizable energy on these variants corresponded to the I and II class of feed.

Crop rotation in agriculture plays an important role. It provides a certain opportunity to assess the state of agricultural production, to analyze the elements of agricultural technologies used in specific natural and climatic conditions, to identify drawbacks, if any, and reasonably direct them towards optimization. The article discusses topical issues of increasing the productivity of field crops in the links of crop rotation against the background of their placement in various ways of the main processing of merged leached chernozems. During 2016–2019 agricultural years studies were carried out to establish the optimal method of soil cultivation and determine the proportion of the influence of predecessors on the productivity of the main crop of the foothill zone of Adygea – winter wheat, in various links of the crop rotation. According to the results of the research, different efficiency of the considered links of graintilled crop rotation was established. So, higher indicators of crop rotation yield and the total yield of fodder units would be achieved against the background of plowing to a depth of 22–24 cm. If we judge the productivity of a particular link in the crop rotation by the yield of winter wheat, it should be noted that in the link «soya-winter wheat», it was maximum and amounted to 4,90–5,86 t/ha, and the average productivity of the unit was 4,80 t/ha of feed units.

The article presents the material obtained as a result of the research for 2017 and 2018, which was laid on leached chernozem in the central zone of the Krasnodar Territory in FSBSI «NGC named after P.P. Lukyanenko», on the basis of the agrotechnological department. The aim of the research was to study the effect of NanoSilicon mineral fertilization with microelements on the yield and quality of sunflower seeds. It was determined that treatment with the studied preparation shortens the interphase periods of sunflower by 1–2 days, increases the height by 8–12 cm and the biomass of one plant by 97–242 grams by the flowering phase. It was also found that NanoSilicon in the studied doses increases the yield and oil collection from 1 hectare. Thus, the inclusion of NanoSilicon preparation in the sunflower cultivation technology at a dose of 15/75/75 (seed treatment – 15 g/ha + spraying on seedlings – 75 g/ha + 75 g/ha in the phase of 5–7 pairs of leaves) significantly increases yield by 0,58 t/ha and oil collection from one hectare by 0,32 t/ha. As a result, 3,23 t/ha of seeds and 1,64 t/ha of oil were obtained.

In 2016–2017 at the experimental selection site of ARSRITTP the influence of modern agrochemicals of Potassium Humate, Bio Fish, Plantafol, Mikrovit, Rexolin ABC, Floroni of the traditional mineral fertilizer ammonium nitrate on the quality of tobacco raw materials of the Virginia variety type from the world collection of the Institute was studied. The dominant indicators of the smoking benefits of tobacco are proteins, nicotine, carbohydrates and chlorine. It has been determined that three-fold foliar treatment of tobacco seedlings in the main phases of development «cross», «ligules» and «fit for planting» with complex agrochemicals improves the chemical composition of tobacco raw materials, and does not change the quantitative indicators of nicotine. The content of water-soluble carbohydrates in raw materials increased by 4–60% and 7–57%, the amount of proteins decreased by 3–11% and 8–16%, respectively, for the years under study. The preplanting application of ammonium nitrate to the soil reduces the quality of raw tobacco. Fertilizer in doses of N60 and N90 helped to reduce the amount of nicotine in tobacco over two years of research by 4–8%, and in doses of N120 and N150 to increase it by 1,5–15,0%. A decrease in the content of carbohydrates in the raw material was established with a decrease in the doses of ammonium nitrate by 39–235% relative to the control. The protein content was at the level of the variant without treatment. The amount of chlorine in the raw material is determined within the permissible limits for good flammability of tobacco (less than 0,4%).

Studying the role and place of state corporations, as well as improving their activities in the framework of stimulating the real sector of the Russian economy is a relevant issue. The subject of the research is organizational and managerial relations arising in the system of functioning of state corporations and their impact on the real sector of economy. The aim of the research is to substantiate the role of state corporations in the development of the real sector of the Russian economy and to develop practical recommendations to improve the efficiency of their functioning in modern conditions. The article reveals the essence, as well as the significant role of state corporations in the innovative modernization of the Russian economy; the necessity of using impressive organizational, financial and economic potential of state corporations in stimulating the development of competitive industries in various sectors of the real sector of the economy is substantiated. There are three main types of state corporations in the Russian economy: a) financial development institutions; their activities are aimed at financing large projects; b) industrial corporations; c) directorates for the implementation of government programs with limited periods of operation and a set of specific tasks for implementation. An analysis of the scale of activity of the state corporate sector has shown that at present state corporations control about 40% of the economy and provide more than half of the state GDP; their financing accounts for about 25% of the expenditure side of the RF budget. The article concludes that state corporations are the locomotives of growth in the real sector of economy, established by the state at the expense of the budget to carry out large-scale projects or to solve important economic and social problems.
