The article presents the results of experimental determination of physical-and chemical parameters, the amount of anthocyanins, the definition of color and organoleptic characteristics of the beverage prepared with ultrasonic extraction method in comparison with the fruit-drink, obtained according to traditional recipe. Black currant was chosen the main raw material for the development of the beverage production technology. It is characterized by a high content of bioactive components that increase the adaptive abilities of human body. The purpose is to use ultrasonic extraction method in the preparation of functionally directed actions beverages. Extractor with submerged ultrasonic emitter was used as an experimental device. The essence of its operation is as follows: a mixture of the extractant and the plant substrate in different ratios was loaded into a container with the emitter, then the ultrasonic generator was turned on. The vibrations of ultrasonic frequency (22 kHz) made high-frequency mechanical vibrations that caused the formation of intense cavitation areas and diffuse dissolution of cell substrates in the extractant in the treated mixture. The ultrasonic extraction technique involves brief contact of berries and extractant (up to 15 minutes) upon application of ultrasonic vibrations. With an increase in exposure time, the yield of biologically active substances increases to reach an equilibrium state corresponding to the most complete exhaustion of raw materials. All this leads to a significant acceleration of the transition from the active ingredients from the raw materials into the extractant to obtain a product with improved physical - and chemical, organoleptic characteristics, as well as a higher antioxidant activity.
