Abstract

One of the most promising areas for the development of the viticulture and wine industry is the use of secondary resources. A new element in the solution of this problem can be the use of the vegetative parts of the vine-growing plant, namely, the red leaves, which have a large supply of antioxidants and other valuable biological substances. Cold winters of the northern regions of Russian viticulture are the strong stress for the grape plant. In these conditions, a large number of biologically active substances, including trans-resveratrol, accumulate in the leaves, which are advantageously different from the raw materials, obtained from the regions of uncontaminated viticulture. The main purpose of the work was to study the biologically active compounds composition of red leaves of various grape varieties, as well as the development of ways to use extracts of red grapes leaves in the food products production. The introduction of a highly concentrated hydrophilic extract of red leaves into a non-alcoholic drink on a grape basis increases the content of biologically active compounds. It is proposed to use the extract of red grapes leaves in the production of fat and oil products, which, when stored, are subject to oxidative and hydrolytic processes. Indicators of oxidative and hydrolytic damage of margarine emulsion with the addition of red grape extract are on average 1.5 times lower than in the control sample. Extract from red grape leaves is an alternative to the currently used green tea hydrophilic extract.
