Currently, considerable attention is drawn to oats for its high content of dietary fiber, phytochemicals and nutritional value. The consumption of oats is believed to have various health benefits such as cholesterol-lowering and anti-cancer properties. Recently, oats have also been considered suitable in the diet of celiac patients. Due to their high nutritional value, oat-based food products such as bread, biscuits, probiotic drinks, breakfast cereals, flakes and baby food are gaining more and more popularity. Research and development of oats and oat products can be useful in the fight against various diseases known to mankind. The aim of the work is to obtain functional products with improved properties through the use of oat bran and whole oat flakes. This research focused on the development of oat-based food products with oat bran and whole oatmeal. For this purpose, breakfasts have been developed by replacing wheat flour with various levels of oat bran (30%; 50%; 80%) while oatmeal has been included at various levels (10%; 15%; 20%) in the recipe. The approximate composition of raw materials and products from oats (moisture, ash, fat, fiber, protein, carbohydrates) was analyzed in the work. The enrichment of oat bran and oatmeal increased the fiber and mineral content of both developed products. The addition of oat products did not affect the organoleptic characteristics of the product.

Today poultry farming in the economy of our country is one of the leading branches of agricultural production due to the fact that it is able to provide a considerable part of the population with high-quality products. That is why the development of new breeds of birds is an important aspect. In this publication, chickens of the Chinese silk breed are considered. A scheme was proposed for the cultivation of Chinese silk breed chickens and broilers for the subsequent comparative characteristics of the breeds. The cultivation and slaughter of birds were carried out on the territory of the farm of the Krasnodar Territory. A comparative assessment of the characteristics of Chinese silk and broiler chickens was carried out in the laboratories of the Department of Technology of Storage and Processing of Livestock Products, the Research Institute of Biotechnology and Certification of Food Products of the KubGAU named after I.T. Trubilin. As a result of cutting the carcasses of the Chinese silk breed (n=5), the following data were obtained: carcass - 2.13 kg, liver - 0.05 kg, heart - 0.04 kg, neck - 0.17 kg, stomach - 0.095 kg, legs - 0.145 kg, head - 0.145 kg, wings - 0.26 kg. During the comparative analysis of chickens of different breeds, positive and negative qualities of Chinese silk chicken were revealed. According to the results of the comparative characteris-tics, the advantages of the Chinese silk bird breed can be considered: exotic appearance, unpretentiousness in maintenance, the use of meat and eggs, resistance to cold, good incubation and survival of offspring. However, there are minor drawbacks: low productivity, high cost of purchasing poultry and eggs. Thus, the database on the comparative evaluation of chicken meat of the Chinese silk breed was replenished.

The process of thermooxidation destruction of industrial butadiene-nitrile copolymers of the grades SKN-18, SKN-26 and substandard products is investigated. The process is carried out in aromatic solvents (toluene in the xylene) under the influence of air oxygen in the presence of an adduct of the radical initiator azodiisobutyronitrile with N-metilpirrolidone. The mass-average molecular weights of the resulting products were determined by gel permeation chromatography, and molecular weight distribution calculations were performed. The influence of the temperature and the content of the initiator on the change in the intrinsic viscosity of solutions of the resulting degradation products, depending on the time of the process, is considered. Based on a comparative analysis of the destruction parameters using toluene and xylene at 80 °C and an initiator concentration of 0.8% by weight. It was found that the type of solvent and the time of destruction practically do not affect the process of thermooxidative destruction with the production of low molecular weight polymers with a molecular weight of 40 ? 103. It is shown that in the course of the destruction of industrial rubbers differing in the content of acrylonitrile, the process proceeds with the formation of higher molecular weight compounds in rubbers with a higher content of acrylonitrile units. When carrying out the destruction of substandard rubber SKN-26SNT with high Defoe hardness, it is necessary to increase the concentration of the initiator to 1.1% of the mass. and temperature. The mechanism of thermooxidative destruction of the studied polymers is considered. According to the data of IR spectroscopy and chemical analysis, it was found that the products of thermooxidative destruction of nitrile butadiene rubbers contain oxygen-containing functional groups. Thus, a simple commercially method for producing low-molecular-weight butadiene-nitrile polymers based on special-purpose rubbers and substandard product with functional hydroxyl, carboxyl and epoxy groups has been developed.

The article deals with the problem of treatment and purification of domestic waste water. Today, many treatment facilities do not have a reagent treatment system and are limited only by mechanical and biological methods of water treatment. We have considered the possibility of using a new scheme for reagent treatment of domestic wastewater. The existing reagent treatment at treatment facilities does not always cope with the tasks of water treatment. It is not possible to achieve the required values for many indicators: COD, residual phosphate content, residual iron content, etc. The water under study was treated with traditional coagulants (iron chloride and aluminum sulfate) and new highly dispersed modified aluminosilicate adsorbents of the KS brand. Lime and alkali were used as alkalizing reagents. A feature of KS grade reagents is their high coagulation-adsorption activity in relation to the extracted components. This is due to the high activity of modifiers on the surface of the aluminosilicate matrix. In the course of the study, a coagulation-flocculation experiment was carried out. During the purification process, the water was examined for the residual content of various components: pH, phosphates, ammonium nitrogen, chlorides, and iron. Effective dosages have been established for each of the reagents used and the possibility of using reagents for the treatment of domestic wastewater to the required standards has been shown. Traditional reagents have shown insufficient efficiency in wastewater treatment. When using iron chloride and aluminum sulfate, it is not possible to reduce the phosphate content to the required values. For the KS reagent, the effective dose was 40 mg / dm3 with the combined use of lime at a dose of 30 mg/dm3

Dietary fiber plays a significant role in the functioning of the human gastrointestinal tract. Their presence in the diet allows you to prevent a number of serious diseases associated with both the digestive organs and the cardiovascular and nervous systems. In order to increase the share of dietary fiber in the population's nutrition structure, it is advisable to create functional products based on traditionally consumed foods enriched with various types of dietary fiber. Such traditional products for the Russian consumer are dairy and lactic acid products, bakery products, meat and fish products, poultry. The article presents the results of an experiment on the introduction of several types of dietary fibers (wheat, oat, potato and psillum plantain fibers) into chopped semi-finished meat products During the study, several recipes of cutlets were developed, according to which culinary products were prepared, which were then analyzed according to organoleptic and physico-chemical parameters. The results of the study showed that the products made using psillum fibers have the highest organoleptic qualities. Cutlets with potato fibers also showed satisfactory results of organoleptic and chemical-physical studies. Both types of cutlets were characterized by a pronounced meat taste and smell, a pleasant consistency, there were no extraneous tastes and inclusions in them. Products with other types of fibers cannot be recommended as functional products due to low consumer qualities (grainy texture, pronounced foreign tastes). The development of semi-finished meat products enriched with dietary fibers without loss of consumer properties will allow expanding the market of functional products in the future.

Abstract: An urgent ecological and technological problem is the purification of natural and waste water from nickel cations and control of their content, since nickel cations belong to the third class and are hazardous to human health. To date, a large number of methods for removing nickel (II) cations from water have been created, the main of which can be considered sorption. In turn, the literature contains a variety of information about the most effective sorbents for cleaning from nickel cations, which sometimes contradict each other. The work determined the equilibrium characteristics of the sorption of nickel (II) cations on various polar sorbents on cation exchangers porous carboxyl Tokem 200, chelated iminodicarboxylic Amberlite IRC 748, gel sulfonic cation exchanger KU-2, experimental phosphoric acid gel KFP; strongly basic gel anion exchanger AV-17, as well as natural adsorbents flint and shungite. Sorption isotherms were obtained and described by the Langmuir equation, and the most promising materials for removing nickel cations from aqueous media were established. It has been determined that the studied sorbents, according to their equilibrium sorption characteristics, can be arranged in the following order: Tokem 200> KFP> Amberlite IRC 748> AV-17> KU-2> Flint> Shungite.

To date, a large number of methods for removing nickel (II) cations from water have been created, the main of which can be considered sorption. In turn, the literature contains a variety of information about the most effective sorbents for cleaning from nickel cations, which sometimes contradict each other. The work determined the equilibrium characteristics of the sorption of nickel (II) cations on various polar sorbents on cation exchangers porous carboxyl Tokem 200, chelated iminodicarboxylic Amberlite IRC 748, gel sulfonic cation exchanger KU-2, experimental phosphoric acid gel KFP; strongly basic gel anion exchanger AV-17, as well as natural adsorbents flint and shungite. Sorption isotherms were obtained and described by the Langmuir equation, and the most promising materials for removing nickel cations from aqueous media were established. It has been determined that the studied sorbents, according to their equilibrium sorption characteristics, can be arranged in the following order: Tokem 200> KFP> Amberlite IRC 748> AV-17> KU-2> Flint> Shungite. The most effective sorbents for removing nickel (II) cations from aqueous solutions can be considered a prototype of a phosphate cation exchanger for gel CFP and a carboxyl porous cation exchanger Tokem 200. separating nickel cations from an aqueous solution.","PeriodicalId":20611,"journal":{"name":"Proceedings of the Voronezh State University of Engineering Technologies","volume":"52 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88401072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Theoretical and practical work is basic to achieving economic security. At the same time, the field of economic security has no clear boundaries, which requires the clarification on it. For present purposes, it is critical to take the specificities, the subject and object of the economic security. Two main methods of research consist of retrospective and theoretical analysis. In order to understand the problem and clarify the field of economic security, we analyzed: the socio-economic context of sourcing and maintaining the scientific and practical interesty; States’ positions and institutional transformation; research findings. As a result, analysis of socio-economic context has led to a pointing at two major areas: 1) economic security of the country, and 2) economic national security. Based on the analysis of documents fixing the "status" of economic security in the Russian Federation, it is concluded that economic security is considered in relation to national security in Russia. A wide range of problems in the field of economic security has been identified: economic security is studied at the micro, meso and macro levels (depending on the facility level); economic security of an organization, municipality, region, industries, state (depending on the management entities); economic provision for national security, national economic security, economic security of the country (depending on target-settings). Two ways of understanding the economic security are revealed based on the analysis of the foreign authors’ research results: economic security in the socio-economic context (1) and national economic security (2). The approach is argued, according to which the field of economic security should be considered as a position of preserving the economic stability and a position of preserving the targets-settings established by the management entities.

Systemic deficiency of vitamin D and silicon compounds in the human body leads to numerous negative consequences, primarily in the field of the functioning of the musculoskeletal system: even in the absence of a lack of calcium and phosphorus compounds, which are considered to be the main bone-forming substances, bone mineralization substances, the likelihood of falls and fractures increases, muscle pain occurs. Based on the known mechanisms of the physiological action of vitamin D and silicon on the human body, it was assumed in this work that a food supplement containing cholecalciferol and water-soluble chelated forms of silicon will have a synergistic effect. It was shown that using solid-phase mechanochemical treatment in the optimal mode, a product containing water-soluble chelated silicon compounds with an equilibrium concentration of up to 24 mg / l is obtained from rice husks and green tea. The optimal mode, characterized by high resistance to instabilities of the technological process, obtaining a product containing chelated silicon compounds from rice husk and green tea, is the rotor speed of the RM-50 semi-industrial centrifugal roller mill-activator equal to 1200 rpm at a feed rate of processing area equal to 43 kg / h. The resulting prototype was used as a solid matrix - the basis for applying cholecalciferol and obtaining a biologically active food supplement. The calculated amounts of the supplement required for consumption to replenish the body's daily need for vitamin D have shown the advisability of using soluble gelatin capsules.
