Influence of Pulse Processing of Plant Raw Materials on the Mass Concentration of Crude Extract in Tincturation Technology

摘要

The paper is devoted to the problem of increasing the total concentration of nonvolatile substances in tinctureduring the extraction process of plant and alcohol-containing raw materials after preliminary pulse processing in themembrane apparatus. Traditionally, biologically active compounds and plant raw materials continue to play a signifi cantrole in the modern food production. One of the main goals of modern food technology is the most complete extractionof valuable constituents from raw material and a decrease in their loss during its further processing. The main stage intincturation is the extraction process, determined by the general laws of mass transfer, the properties of plant tissue, andchemical and physical affi nity between the solvent and extracted substance. The article describes the disadvantagesof extraction as a method of extracting constituents from plant raw materials and methods to increase the effi ciency ofthis process. The aim of the paper is to research the possibilities for the application of pulse processing of plant rawmaterials at the preliminary processing stage to increase the yield of extractive substances of the fi nished product forexample of tinctures. The scheme of the developed pulsation apparatus and optimum modes of raw material processingare presented according to the previously conducted research. Infusion technology and control methods for basic qualityindicators are taken according to the standard technology. The results of experimental research into the infl uence ofpulse processing on the yield of extractive substances confi rm the possibility of using this type of preliminary processingof plant raw materials.
