Chromatographic studies of extractant residues in the chemical technology of carotenoid production

Abstract

Selected parameters of gas chromatographic analysis, which allow to determine and control the purity of industrial carotene preparations for nutrition and medicine purpose. It has been discovered that undesirable accumulation of chemical reagents in carotenoids in the course of a multi-stage and longterm biomaterial extraction mode requires additional purification from the residues of dangerous extractants.
