Elaboration the technology of high concentration supercritical CO2 -extracts using wheat germs, and other raw plant materials

Abstract

We study the technology of extraction from vegetable raw materials biologically active substances with a clean and safe solvent, supercritical (SC) carbon dioxide (CO2). The study of the extraction process performed on a laboratory pilot plant CO2supercritical fluid extraction. The experimental work carried out by using raw materials wheat germ and Milk thistle (grown in the country Moldova and Romania). It is established that the technology allows to obtain highly concentrated extracts of biologically active agents in their native proportions, free from residues of solvent.
