NOVEL METHODS OF ISOLATION OF POLY UNSATURATED FATTY ACIDS

摘要

A process is described comprising one or more of a step of separation, isolation, purification, concentration, hydrolysis of one or more of a lipid in general or its/their derivative, from a process stream; wherein the said lipid comprises any fat soluble natural molecule and the said process comprising selective capture of lipids or other derivatives on an adsorbent and washing followed by elution using either a solvent for lipids or an alkaline alkanol. The said process stream may be an emulsion of crude oil or sonicated suspension of microbial biomass. Solution of isolated fatty acids obtained during the process may be subjected to nano-filtration to achieve enrichment of polyunsaturated fatty acids.
