The quality characteristics of technical grapes and wines largely depend on the management system of this culture. The aim of the study was to establish the influence of various norms of the load of a grape bush in a self-rooted and grafted culture on the yield, quality of grapes, as well as the aesthetic and biological value of wine products in the conditions of this terroir. The experiment was carried out in 2018-2019 in Temryuk district of Krasnodar region. The objects of research were grapes and wine material of Krasnostop AZOS variety in a grafted and rooted culture with a different load of shoots on the bush. The plantation was established in 2007 according to 3 × 2 m scheme, the formation of the bush was a spiral cordon AZOS-1. The soil of the experimental site is soddy-calcareous, thick, low-humus, light-clayey granulometric composition, formed on tertiary saline clays. The upper horizon (0-60 cm) has favorable agrochemical properties and a sufficient level of fertility. The normalization of the load by shoots of grape bushes cultivated in a self-rooted or grafted culture had a significant impact on the yield and technological qualities of Krasnostop AZOS grape variety during the years of the study. The highest yield result was provided by the variant of own-rooted bushes Krasnostop AZOS with standardized shoots 36 ... 40 pcs/bush - 3.45 kg/bush. The excess yield was significant at the 5% significance level in comparison with the control and other variants of the experiment and amounted to 0.45-0.9 kg/bush. The best ratio of sugar content and titratable acidity (standard glucose value - 4.36) for dry red wines had a variant of own-rooted culture with a load of shoots of 36-40 pcs/bush. In the investigated variants, the highest concentration of phenolic substances was in wine from self-rooted grapes with a load of 36 ... 40 shoots per bush - 4130 mg/dm3. This had a positive effect on the organoleptic evaluation of this sample. The maximum total content of substances from a number of biologically active substances was found in wine from grape raw materials obtained from the grafted culture (134.9 ... 147.9 mg/dm3). According to the results of two years of research, the optimal concentration of biologically active substances in the range of 120-135 mg/dm3, which, in combination with other wine components, is able to provide the best quality of dry red wine. In 2018-2019 from the organoleptic point of view, wine materials from grapes of own-rooted culture proved to be of the highest quality. This advantage over the grafted crop was traced in all variants of rationing the load by the shoots of grape bushes.

Under the conditions of changing biotic properties of terroir, it is relevant to establish the patterns of influence of different norms of the load of a grape bush in its own rooted and grafted culture on the quality of grapes, as well as the aesthetic and biological value of wine products in Russia. The objects of research were grapes and wine material of the Krasnostop AZOS variety in a grafted and rooted culture with variants of different load of shoots on the bush. The experience of studying the influence of various agrotechnical methods on the productivity of a grape plant and the quality of wine material was laid in the Anapo-Taman climatic zone of the Krasnodar Territory of Russia. The highest yield of the Krasnostop AZOS variety during the years of the study was obtained in the variant of own-rooted grape growing with its load of 36-40 shoots per bush. In our studies, there is a tendency to an increase in sugar content, and a decrease in the titratable acidity of grapes when growing vineyards of the Krasnostop AZOS variety in their own rooted culture. The most optimal ratio of sugar content and titratable acidity in the experiment was possessed by grapes from a variant of own-rooted culture with a load of 36-40 shoots/bush, here the glucoacedometric parameter was 4.36. In the studied variants, the largest amount of phenolic substances was found in wine material from self-rooted grapes with a load of 36-40 shoots per bush — 4130 mg/dm3. This had a positive effect on the organoleptic evaluation of this sample. The maximum total content of substances from a number of biologically active substances was found in wine from grape raw materials obtained from a grafted culture (134.9-147.9 mg/dm3). In 2018-2019, from the organoleptic side, wine materials from grapes of own-rooted culture proved to be of the highest quality. This advantage over the grafted crop was traced in all variants of rationing the load by the shoots of grape bushes.

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.

Medicinal plants (Cotinus coggygria, Dactylorhiza maculata, Platanthera chlorantha) growing in various territories (Kaliningrad, Moscow, and Minsk regions) were the objects of research. This paper presents a study of the chemical composition of these plants. To analyze the qualitative and quantitative composition of biologically active substances, the method of high-performance liquid chromatography was used. Atomic absorption spectrometry was used to study the content of trace elements. The content of organic acids and vitamins was determined by capillary electrophoresis using the Kapel-105/105M capillary electrophoresis system with high negative polarity. Extracts of medicinal plants were obtained on a Soxhlet apparatus using 70% ethanol as an extractant. It was found that among the biologically active substances in the plants under discussion, hyperoside, rutin (C. coggygria), Ferulic acid and Gallic acid (D. maculata), triene hydrocarbon (3,7-Dimethyl-1,3,6-octatriene), unsaturated alcohol (3,7-Dimethyl-2,6-octadien-1-ol), and benzyl acetate (P. chlorantha) prevailed. Samples of these medicinal plants contained trace elements (phosphorus, potassium, calcium, sodium, magnesium, and sulfur) and many aliphatic organic acids (succinic acid, benzoic acid, fumaric acid, citric acid, oxalic acid, and tartaric acid). The largest amount of biologically active substances and secondary metabolites of the studied plants from the Eastern Baltic is associated with climatic and ecological differences from other regions. The composition of these plants determines the potential of their use in feed additives for livestock and poultry as part of measures to improve the quality of livestock products. The use of medicinal plants for the production of feed additives is relevant in terms of improving regional economies, as well as improving the quality of life and nation’s health by providing ecologically clean livestock products.

Knowledge of analytical values in wines is essential to ensure product safety and compliance with legislation, and it is also essential to understand the various technologies in wine production. The aim of this work was to evaluate the analytical parameters of bottled Moravian wines from the Znojmo sub-region, from harvests 2015 and 2016. Basic oenological parameters and biologically active substances were evaluated. Moreover, we evaluated conditions during bottle aging in wines from harvest 2016. The results of the basic analytical values such as total phenolic acid (TPA), total sulfur dioxide (SO2), pH, actual alcohol content (EtOH), and titratable acidity (TA) were in accordance with generally known values in wines and met the legislative requirements within oenological practices. Biologically active substances, such as gallic acid, trans-caffeic acid (TCA), trans-p-coumaric acid (TPCA), rutin, ferulic acid (FA), myricetin, resveratrol, and quercetin were identified. Comparing the analytical values of individual types of wine leads to a better understanding of winemaking technology and the development of wine as such. The subject of the study was also the monitoring of produced grape pomace incurred during wine production harvest 2015 with the indication of possibilities of its further use.
