  The article is devoted to the study of the chemical composition, physical and thermal-pfysical characteristics of damp apple pomaces and the identifying patterns of influence of drying temperature the functional composition and gel-forming ability of pectin. The research is aimed at obtaining initial data for the subsequent calculation of the main technological, hydro-mechanical, thermal, structural and economic characteristics of devices for drying the plant raw materials, ensuring the environmental safety and high quality of pectin-containing raw materials, the reducing heat and energy costs. As a result of the study of the thermal characteristics of apple pomaces, the critical points (temperature conductivity – 16.5 x 10-8 m2/s, thermal conductivity – 0.28 W/m K, heat capacity – 1627 j/(kg K)) at a humidity of 56 % are determined, which characterizing the transition from the extraction of weakly bound moisture to the extraction of moisture with strong bonds (colloidal, adsorption). It was found that the pomaces obtained from apples of late ripening have a higher content of solids (21-23 %), soluble pectin and protopectin (2.5-4.5 %). Dried pomaces obtained from apple varieties of late ripening contain up to 25 % pectin, which allow us to recommend them as a source of raw materials for the production of pectin. The optimum modes of preliminary washing of raw materials are offered, allowing to the remove the ballast substances as much as possible. It is established that when the drying temperature increases, the destructive processes are catalyzed: the strength of the pectin jelly and the uronide component and the degree of pectin esterification are reduced. The optimum drying temperature of damp apple pomaces is 80 0C, at which the quality of pectin extracted from the dried raw materials is maintained as much as possible. It is shown that the most effective for the pectin production is a fraction with a particle size of 3-5 mm, which allow us to extract up to 71 % of pectin from raw materials.

Background. The deficiency of essential nutrients in the human body is the root cause of reduced efficiency, general resistance of the body to various diseases. That is an urgent problem in the context of the spread of coronavirus infection. In this regard, the search for opportunities to meet the needs of the population in food products that contain biologically active substances (BAS) through the use of high-value and at the same time available plant raw materials is extremely important. Marigolds attract special attention among such raw materials. The aim of the work is to study the chemical composition and evaluate the consumer properties of Tagetes L. varieties, zoned in the Kiev region, to prove the possibility of increasing the biological value of pasta by adding to their recipe powder from marigold inflorescences. Materials and methods. The object of research is pasta of B group (noodles). Inflorescences of marigolds of different varieties gathered during the flowering period in July-September 2019–2020 in the territory of Vasylkiv and Obukhiv districts of Kyiv region, Ukraine were used as enriching plant raw materials. The quality of finished pasta was assessed by organoleptic and physicochemical indexes (moisture content and titratable acidity). The content of mineral elements in the fine powder of marigold inflorescences was determined on the EXHERT-3L device, the quantitative composition and BAS identification – by spectrophotometric analysis on the device Specord-200 Analytic Jena UV-vis. The integrated quality index of pasta products was calculated taking into account the importance factors of individual indexes. Results. Comparing the obtained results, we can state that all the studied varieties – Gold Kopfen, Orange Flame, Hawaii, Equinox are characterized by high biological value, regardless of the area of collection. As a result of calculated and experimental studies it was determined that the addition of 7 % of the supplement does not provide the required supply of vitamins and minerals. Replacing the flour in the recipe by 20 % significantly improves the mineral composition, but deteriorates the taste and aromatic properties of pasta. The most optimal and rational amount of added additive is 15 %, as it improves the organoleptic properties of pasta and enriches their BAS. Conclusion. The usage of non-traditional vegetable raw materials, in particular powder from marigold inflorescences, which is rich in biologically active substances, allows not only to expand the range, improve the quality of finished products, but also increase the biological value of the product. The optimal amount of additive –powder from marigold inflorescences, was defined. It is 15 % by weight of flour in the production of noodles. This concentration allows not only to improve the organoleptic properties, but also to increase the content of biologically active substances – vitamins, micro- and macronutrients. The usage of non-traditional natural raw materials (powder from marigold inflorescences) allows to abandon artificial colorsand give the finished pasta a pleasant colorand aroma.

The development of targeted beverages is a priority for healthy eating. Plant raw materials containing a wide variety of biologically active substances are used for their production. The presence of these ingredients helps to improve many physiological processes in the body, as well as to increase its immune status. The high efficiency of ultrasonic effects on various technological processes was confirmed by numerous studies. Ultrasonic extraction was carried out at t = 20 ? and an ultrasonic wave frequency of 22 kHz. As a result of the research, it was found that the equilibrium state is achieved within 15 minutes with ultrasound exposure. Natural raw materials, their chemical composition and the influence on the human body were studied in the work to develop new beverages recipes. The selected ingredients in a certain quantitative ratio made it possible to obtain beverages with improved bio-corrective properties, which allows satisfying the daily requirement of the human body for biologically active substances. Ultrasonic exposure has a positive effect on the organoleptic characteristics of the beverage and the aftertaste, as proved by the comparative organoleptic evaluation of the samples. The functional properties of the beverages developed were confirmed experimentally. The following was determined in the beverages: macronutrients content, antioxidant activity, vitamin C content, shelf life duration. The ultrasonic extraction method application in the technology of beverages manufacturing allows: to reduce the preparation time by half, to reduce the amount of raw materials by 15%, to increase the content of macronutrients by 45%, to increase the content of vitamin C by 35%, to increase the antioxidant activity by 45-50%, to increase storage stability by 50-60%, to improve organoleptic characteristics. The results obtained prove the intensifying effect of ultrasonic exposure in the production of functional beverages.

The article considers the methodology of scientific research at enterprises, the main emphasis is placed on the issue of audit and innovation in improving enterprise management. Yes, today the world is in crisis in the economy due to the COVID-19 virus. However, appropriate measures are needed to get out of this situation as soon as possible. Universities pay special attention to research that provides new knowledge, helps in solving problems, decision-making, discovery, invention, conflict resolution. Without "theory", appropriate research, practice is impossible, as the article proves. Yes, an important factor that determines the success of the audit is the audit. Its absence causes a crisis in the company, which can lead to bankruptcy. Therefore, sufficient attention should be paid to the issue of audit in scientific research. Moreover, innovations contribute to the development of enterprises. However, it does not make sense to implement them without appropriate scientific and financial research - innovations must be relevant to the company, make a profit after their implementation, as well as stimulated by the state. However, it is equally important to take into account innovation, environmental friendliness and profitability. Food quality management depends not only on the company that produces them, processing technology, suppliers of raw materials (agriculture), but also on medical standards, recommendations, marketing, consumer market research, their features. Production in the world is becoming human-oriented, so it changes the guidelines, management not only in the enterprise but also in the regions and society. It is no coincidence that in international practice more and more often to determine the quality of life in the country instead of GDP use the happiness index, which includes along with the level of income and life expectancy. There is a need to "supplement" medical expertise with economic and environmental ones. We are talking about the "birth" of a new medical, economic and environmental examination of food products (MEEEFP). The higher the quality of food, the higher its competitiveness, better management in a saturated market, the quality of the environment and the quality of labor reproduction, increase life expectancy, GDP of the region and the country. This quality can be achieved only with the help of innovative technologies.

With the increase in the world population every year, the need for plant and animal foods has increased. In order to meet these needs, the amount of fertilizers (with chemical content) used to increase productivity in agriculture has increased and has become a threat to the soil and the environment. In order to minimize the harms of chemical fertilizers and to preserve the fertility of the soil, new environmentally friendly applications have been researched. In this context, studies on "Plant Probiotics", which are one of the effective applications both in protecting the quality of the soil and increasing the yield in plant production, especially on local isolates and formulations to be prepared from them, have gained momentum. Plant probiotics are a group of microorganisms or microorganisms that can improve soil health, plant growth, and plant tolerance or immunity to various abiotic and biotic stresses, thanks to their potential role in enhanced nutrient acquisition and/or biocontrol activities by colonizing the root zone of plants, called the rhizosphere. As a result of inoculation of plants with strains of these bacteria, which have very different properties (nitrogen binding, phosphate solubilizing, biocontrol agent, stress resistance, phytohormone synthesis), it directly affects the growth and development of the roots and shoots of the plant, increasing the biomass, as well as contributing to the increase of the yield and quality of the product. In this context, the preparation and use of biofertilizer formulations of local plant probiotic bacteria, which will be obtained from their natural areas, has become very important in rational agricultural practices in recent years and intensive researches are carried out. With the use of the aforementioned plant probiotic formulations, environmentally friendly green production will be made by contributing to the production of both foodstuffs and feed raw materials in order to ensure the continuity of the world population. As a result, the protection of the ecosystem will be ensured by preventing environmental pollution, which is the problem of the whole world.

The article provides an analysis of key trends in the international market, using the example of the countries of Northeast Asia. In 2019, the world coal market amounted to 1,424.5 million tons, of which 78.1% are energy grades to produce electricity and heat, and 21.9% are in metallurgy, the reserves of which are significantly less. The import coal market of the countries of Northeast Asia in 2019 was already 680 million tons, covering 48% of the entire world coal market. The paper provides an overview of the key importers and exporters of coal in the world, the quantitative and qualitative characteristics of the supplied raw materials, and analyzes the key factors affecting the pricing of coal. In the conclusions, the main trends in the international coal market of the countries of Northeast Asia are presented, including "geographical" — the shift of the center of world trade from Europe to Asia, and "types and quality of imported coal" — an increase in the share of high-quality premium energy and coking (metallurgical). Trends can be clearly seen in the countries of Northeast Asia, which actively use coal, and are making efforts to decarbonize their national economies, while intensifying inter-fuel competition with other primary energy sources.

Ginseng roots, Panax ginseng C.A. Meyer, obtained from cultivated ginseng grown in the Kaesong province (North Korea) and Primorye (Russia) were extracted using the supercritical CO2 extraction method. The extracts were subsequently analyzed by high-performance liquid chromatography with tandem mass spectrometry identification. The results showed the spectral peaks of typical ginsenosides with some other minor groups, and major differences were observed between the spectra of the two ginseng samples. The use of a pressure of 400 bar and higher allowed an increase in the yield of ginsenosides in comparison with similar previous studies
