Development of a technology for obtaining a polyphenolic biologically active additive from grape pomace for a wide range of applications

Abstract

The research work considers the development of a technology for processing secondary raw materials of winemaking, which, due to preliminary preparation, passes into the category of enriched high-quality environmentally friendly grape raw materials. This study is carried out with the aim of obtaining concentrated high-quality polyphenolic biologically active extracts that can be used as a functional raw biomaterial for a wide range of products: healthy/sports nutrition, medical and preventive cosmetics, alcoholic and nonalcoholic drinks, and other types of special functional additives. The novelty of the development lies in the fact that at the initial stage, the enrichment of raw materials with target polyphenolic compounds is carried out using effective supercritical fluid CO2 extraction, followed by the use of the obtained AGP** extracts in the form of a finished product - a phytopreparation with inherent functional properties.
