The article deals with the creation of beverages with functional properties for the healthy nutrition of the country's population from the fruits of rare crops. The necessity of including functional foods with a high content of natural antioxidants that increase resistance to adverse environmental factors in the diet of the country's population is indicated. Chemical indicators of the quality of fruits of such rare crops as viburnum, rose hips, barberry and hawthorn have been studied. It has been established that viburnum fruits contain 18.5 mg/100 g of vitamin C, more than 100 mg/100 g of vitamin P, polyphenols; in rose hips more than 100 mg/100 g of vitamin C, more than 200 mg/100 g of vitamin P, more than 2 mg/100 g of vitamin E, β carotene and pectin substances; barberry fruits contain a high content of vitamins, polyphenols, β-carotene and minerals (up to 425.4 mg/100 g of potassium, up to 51.2 mg/100 g of calcium); hawthorn fruits contain vitamins C, P, E, polyphenols, β-carotene, potassium more than 598.0 mg/100 g and calcium more than 137.8 mg/100 g, which makes it possible to attribute them to the group of crops with a high content of macronutrients. Technological modes of preparation of extracts from fruits of rare crops are optimized, taking into account pH, temperature and hydrolysis time. Formulations of functional beverages have been developed using fruit extracts and puree from the fruits of barberry, viburnum, hawthorn and rosehip with a high content of antioxidants. The total content of natural antioxidants in the drink Vitaminnyi is 425.7 mg/100 g, in the drink Zdorove 350,5 mg/100 g.
The influence of the characteristics of new varieties and hybrids based on Krasnostop Anapskiy variety on the quality of grapes and chemical and technological parameters, and taste characteristics of wine products was studied in the experiment. The author in the article presents research materials on must and dry wine materials from hybrid varieties and forms of crossed pairs of grapes (F/U Dzhemete x Krasnostop Anapskiy) bred at the Anapa Zonal Experimental Station of Viticulture and Wine-making. All new varieties and hybrid forms of a technical direction, average term of maturing. Productivity is high, they are tolerant to phylloxera. The must and wine material from the Krasnostop Anapskiy variety was used as a control. Place of laying the experiment is Anapa, Krasnodar region, Anapa ampelographic collection. Pruning of vineyards is Spiral cordon AZOS-1. The feeding area is 3.5 x 2.0 m. As a result of the analysis of fresh grapes from the studied varieties and hybrids, it was revealed that all the studied varieties and hybrids, with the exception of the 59-60 form, accumulated a fairly high amount of sugars 19.9-22.9 g/100 cm3 . The must of Krasnostop AZOS and Kubanets varieties and 59-24 form had a concentration of phenolic compounds significantly higher than the control. The most optimal in terms of glucoacidometric index was the mustof the control variety Krasnostop Anapskiy and 59-49 and 59-24 forms. The wine materials of most of the studied varieties and hybrids were not inferior to the control in terms of alcohol concentration. The highest concentration of substances of the polyphenol group was found in wines from the hybrid 59-24 and from the Krasnostop AZOS and Kubanets varieties. Coloring anthocyanin substances in the highest concentration were found in the studied wine materials from hybrid grapes 59-24 and 59-60, as well as from the Krasnostop AZOS variety. The tasting analysis showed that the wines from the studied hybrids and varieties are not inferior or superior in organoleptic parameters to the control variety Krasnostop Anapskiy.
The transformation of the appearance of apple must depending on the variety of apples is investigated. Apple must obtained during the processing of 30 varieties and elite forms of domestic and foreign breeding, and apple ciders were used as objects of research. It was shown that during processing, good juice separation was in the varieties Florina, Zolotoye letnee, Orfey, Ekzotika, Prikubanskoe, Dzhin, Chempion, Renet Platona, Liberti, Margo. All studied elite forms were characterized as fibrous with difficult sap secretion. Clarification of must, which was carried out by settling, proceeded slowly, especially in specimens whose consistency was characterized as puree and fibrous. As a result of fermentation, there was a change in the consistency, intensity and shade of color. In most samples, partial self-clarification was noted. Samples of ciders produced from apple varieties Orfey, Margo, Prikubanskoe, Virginia, Enterprise, Imrus, Ekzotika, Karmen, Vasilisa, Florina, Dzhin at the end of fermentation straw with a greenish tinge color and well lightened. Ciders from the varieties Soyuz, Amulet, Liberti, Ligol, Persikovoe, Ketni, Zolotoye letnee, Bagryanets Kubani, of all forms remained cloudy. The color and its intensity differed: samples of ciders from the varieties of apples Soyuz, Persikovoe, Ligol, of all elite forms had an amber color, which is associated with the peculiarities of the phenolic complex, in particular, with the content of anthocyanins. The shade of color varied in a wide range: from greenish to light yellow, yellow, light brown, pink and dark pink. The obtained data must be taken into account when compiling blends of ciders in order to regulate their color.
The current area of research is a comprehensive study of varieties, forms and clones of local breeding for a reasonable selection of modern varieties. The aim of the study was to study the biochemical and technological characteristics of varieties, forms and clones of grapes bred by NCFSCHVW in the edaphoclimatic conditions of the Kuban. The objects of research were varieties, forms, clones of the NCFSCHVW breeding (9 white-berry, 11 dark-berry and 4 control varieties), as well as fresh grape must and dry wine materials obtained from them. Wine materials were prepared according to classical technologies for low-oxidized white wines and red wines with a floating cap. The mass concentrations of sugars and titratable acids were determined in the must. Physicochemical and organoleptic characteristics, indicators, composition of aroma-forming components and individual organic acids were determined in wine materials. A complex of phenolic substances, vitamins and vitamin-like substances was studied in red wine materials. It was established that the must of the studied samples had moderate mass concentrations of sugars and titratable acids: white berry 19.1-22.5 g/100 cm3 and 7.6-8.3 g/dm3 , respectively; dark berries 20.2-24.4 g/100 cm3 and 6.8-8.0 g/dm3 , respectively. It was noted that the group of Tana forms was distinguished by a higher volume fraction of ethyl alcohol of 11.8-12.5 % vol. In a sample of dry wine material Tana 95, a higher content of esters (89.8 mg/dm3 ) was noted, among red ones in wine materials Tana 33 (116.8 mg/dm3 ), Kurchanskiy (100.1 mg/dm3 ) and Cabernet Kuban (105.2 mg/dm3 ). The mass concentration of higher alcohols in dry wine materials from the white berry forms of Tana (295.9-349.8 mg/dm3 ) exceeded the classic varieties and proto-clones from the Chardonnay and Riesling lines (192.6-264.4 mg/dm3 ). Vladimir stood out by the amount of phenolic substances (3603 mg/dm3 ), Tana 85 distinguished according to the accumulation of anthocyanins. Kurchanskiy, Vladimir and Tana 85 were isolated according to the amount of vitamins and vitamin-like substances.
Currently, financial success in the market can be provided by varieties of fruit crops that have a complex of economically valuable and adaptively significant characteristics, at the same time, characterized by high yield capacity, proper presentation, transportability and the ability to long-term storage. The key to the cost-effective maintenance of an apple orchard is determined by rational technology, proper care of trees, and the correct selection of varieties. It is worth noting that the average yield capacity of apple fruits on the Don in the years before the reforms did not exceed 40-50 kg/ha. The low yield capacity is explained by the lack of an irrigation system in the orchards, the use seed, strong-growing rootstocks as the main, the rare standing of trees (250-300 tree/ha) in the orchard, an unsuccessful choice of varieties. The determination of the most suitable varieties for the selected climatic zone became the purpose of the research. So, in 2012, in the conditions of the Azov zone of the Rostov region, an intensive type orchard was planted on an area of 84 hectares, in which eight apple varieties of different ripening periods were placed. When laying the garden, mainly new varieties with increased resistance to diseases and pests were used. The rootstock of seedlings is weakly growing, vegetatively propagated M9 (paradizka 9, EM 9). Tree planting scheme is 3x1 m (3m2 /tree, 3333 tree/ha). In the course of our work, the fertility of these varieties, yield capacity, the influence of climate and temperature on trees, as well as resistance to diseases and pests were analyzed. Based on the obtained data, optimal varieties of various maturation periods for cultivation in the Azov zone of the Rostov region were established.
