The article highlights the issues of food supply today and ways to solve them, the beneficial properties of meat products, consisting of full-bodied proteins from animal raw materials.

During the production of meat products, it was shown that natural plant materials, including sea buckthorn, are a promising source rich in substances useful for the human body.

When adding a sea buckthorn product in the form of a powder to minced meat for cutlets, its effect on the physicochemical and structural-mechanical properties is studied, as a result it is proved that the addition of 4-5% sea buckthorn powder to minced meat has a good effect on its acidic environment, changes in mixing stress and ultimate shear.

The article presents the results of a study of the methods and directions of research of social networks. A brief overview of the methods of social network analysis that are used to identify the relationship and interaction between network participants, their classification and prediction of behavior is provided. Using these methods, you can analyze objects such as the social network itself, intra-network networks and communities, individual users, informational messages, opinions, external nodes. The paper describes the most popular areas of social network research: structural, normative, resource and dynamic. The problems of data collection, the scope of application of the results of the analysis of social networks are analyzed. The tasks to be solved with the help of research directions of social networks are given. Some characteristics useful for studying social networks are also presented, methods and algorithms used in various models of social network analysis are briefly outlined.

The relevance of the study lies in the processing of meat and bone raw materials for food purposes, thereby increasing the waste-free technology in the meat processing industry. The article describes the technology for obtaining chicken meat and bone paste by finely grinding meat and bone raw materials on a crusher and a micro grinder. The results of determining the size of bone particles and the microstructure of chicken meat and bone paste are presented. It follows from the research results that bone particles in chicken meat and bone paste are within the set gaps, which contributes to its safe use in the technology of meat products. The composition of bone inclusions in chicken meat and bone paste does not exceed 0.25 mm, while more than 90% of bone particles are no more than 0.1 mm in size. The average size of bone particles according to the measurement results was 0.044 mm.  

The resulting chicken meat and bone paste can be used later as a food additive for the production of combined meat products (pates, chopped semi-finished products, meat fillings, boiled sausages, sausages, etc.), enriched with elements that are necessary and useful for humans. The production of meat products with the addition of meat and bone paste to the recipe can improve the nutritional value of meat products.

The author proposed a simple method for determining the composition of amphoteric cryogels based on the method of potentiometric titration. Complex equipment and highly qualified employees are not required to perform the analysis. The proposed method has shown effectiveness on the example of a copolymer of methacrylic acid and dimethylaminoethylmethacrylate. The ratio of acidic and basic groups in the structure of cryogels based on crosslinked copolymers with different degrees of crosslinking has been established.

The article presents the results of a study on the use of organic pesticides in the agroindustrial complex, including organochlorine, organophosphate, which belong to dangerous pesticides.

It should be noted that not only the violation of the norms for the use of pesticides in the agro-industrial complex negatively affects the environment and human health. As studies by foreign and domestic scientists show, pesticides have the ability to accumulate in living organisms, persist for a long time in the soil and in plants after their treatment, as well as with prolonged and repeated use of pesticides, harmful objects develop resistance to their effects. For a long time, the harmful effects of pesticides were considered without taking into account their relationship in the "soil – water – plant – products" system. Many pesticides persist in the soil, due to slow decomposition, and enter groundwater and surface waters. As a result of prolonged use, pesticides accumulate in animal tissues along the biogeochemical chain and enter the human body. Even at a low dose, but with repeated use of pesticides, they can pose a serious danger to human health and the environment.

The article is devoted to assessing the suitability of Turgoyak lake water for drinking purposes. Water quality assessment was carried out according to the following hydrochemical parameters: BOD5, content of petroleum products, pH of water, compounds of copper, zinc, manganese, lead. It was revealed that according to indicators of pH of water, compounds of copper, lead, water of the lake in 2020. met the established norms. In the water of the lake, some excesses of iron and zinc norms were noted. An excess of the content of petroleum products in the water of the lake was found in 16.7% of the samples, which indicates the presence of anthropogenic load on the water area of the lake, which belongs to the OOPT. The study of the water quality of Lake Turgoyak showed that the water does not fully correspond to the quality of drinking water, especially in the summer period, which is most likely due to the introduction of easily oxidizable organic matter into the reservoir from the catchment.

This paper discusses the results of studies of the properties of Ni-Cr-Al wearresistant detonation coatings obtained at different values of the volume of filling the detonation barrel with an explosive acetylene-oxygen mixture. The thickness of the obtained detonation coatings NiCr-Al was 214-288µm. When the barrel is filled with an explosive gas mixture of 40%, the coating is not dense enough, with noticeable boundaries between individual particles, which may be the result of insufficient heating and acceleration of the particles of the sprayed powder. Higher values of microhardness were obtained at 50% filling of the barrel. The results of tribological tests of coatings have shown that the coating applied when the volume of filling the detonation barrel with an explosive mixture is up to 60 %, has a lower wear rate than other coatings. Visible that the mass loss at 50% of the detonation barrel filling volume is less than other coatings.

This article provides basic information about the history of unmanned aerial vehicles and their areas of application in the modern world. They can be used not only for military purposes, but also for civilian ones, helping people perform a number of tasks, such as: delivering food or medicine; drawing up maps and routes; search for people after emergencies, shooting in hard-toreach places. The functionality of these devices is expanding, the developers have already created amazing examples of medical drones that can provide first aid, or deliver the necessary medicines to remote areas in a short time; and aqua drones, which have a waterproof surface and film the underwater life of their inhabitants. When creating maps, drones play an important role, thanks to them, three-dimensional maps of the area are created. Many navigation systems create routing programs thanks to pre-programmed drones that study the territory given to them. Futurologists are sure that not all the possibilities of modern technologies are developed to the proper level. And drones are no exception, their potential and capabilities will still be improved.

The article considers development of distributed system of organization of practical and laboratory work, for complex use of laboratory equipment.

The transition from the development of the specialty to training in the areas requires students to obtain a large amount of productive skills, and from the educational institution skills, and the main availability of opportunities to provide them with this opportunity. One of the directions in the development of a new approach to the organization of the educational process in the field of obtaining and developing industrial competences is a change in the approach to the use of laboratory equipment available at the school.

This article proposes a distributed system based on the modular controller compact RIO9035, acting as the kernel of the entire system. Data transfer from the laboratory equipment to the controller is performed using the Arduino UNO platform. The Arduino Uno platform acts as an interface hub/converter.

This system will allow students to use laboratory equipment in a comprehensive manner and to study disciplines in their specialty.
