The paper is devoted to the problem of increasing the total concentration of nonvolatile substances in tincture during the extraction process of plant and alcohol-containing raw materials after preliminary pulse processing in the membrane apparatus. Traditionally, biologically active compounds and plant raw materials continue to play a significant role in the modern food production. One of the main goals of modern food technology is the most complete extraction of valuable constituents from raw material and a decrease in their loss during its further processing. The main stage in tincturation is the extraction process, determined by the general laws of mass transfer, the properties of plant tissue, and chemical and physical affinity between the solvent and extracted substance. The article describes the disadvantages of extraction as a method of extracting constituents from plant raw materials and methods to increase the efficiency of this process. The aim of the paper is to research the possibilities for the application of pulse processing of plant raw materials at the preliminary processing stage to increase the yield of extractive substances of the finished product for example of tinctures. The scheme of the developed pulsation apparatus and optimum modes of raw material processing are presented according to the previously conducted research. Infusion technology and control methods for basic qual- ity indicators are taken according to the standard technology. The results of experimental research into the influence of pulse processing on the yield of extractive substances confirm the possibility of using this type of preliminary processing of plant raw materials.
