Grape squeezes are a valuable secondary raw material, and therefore an interest has increased in their use to maximize the extraction of biologically valuable components and to obtain the new types of products, including dietary supplements. An important source of biologically active substances are squeezes, seeds and skin of grapes, which contain the significant amounts of essential substances. The works on the integrated and rational use of raw material should be aimed at creating such a technology for processing raw material that minimizes and in some cases virtually eliminates the generation of waste. The use of secondary products of grape processing in food processing tech-nologies will reduce the cycle of technological process, which will lead to saving in the main raw material while maintaining guaranteed organoleptic and physico-chemical quality indicators, as well as reducing the costs during its processing. As an object of research, we took seven samples of secondary raw material of grapes processing (grape squeezes) grown under the soil and climatic conditions of the Taman Peninsu-la. The article describes the mechanical composition of dry raw material, as well as the quality indicators of grape squeeze including skin and stones containing vitamin P (193.3 mg / 100 g), C (8.8 mg / 100 g) and E (0.75 %); pectin substances � 1.52 % (0.67 % soluble and 0.85 % protopectin). It is noted that the grape squeezes contains many biologically active substances that have therapeutic and prophylactic significance for the body. It is concluded that the grape squeezes are a source of valuable food components. The powder obtained from the grape squeezes is very likely to use as an enriching component of fruit puree products � jam, jelly, functional soft drinks to give them therapeutic properties.
