RESEARCH ON USING PHOSPHOLIPASE A1 AS CATALYSIS FOR MODIFYING THE FATTY ACID COMPOSITION OF PHOSPHOLIPID

Abstract

Modified phospholipids were synthesized by acidolysis reaction between soybean phospholipids (also known as lecithin) and conjugated linoleic acid (CLA) using phosphlipase A1 as a catalyst. The reactions were carried out for 48h in a solvent-free or organic solvent systems. The fatty acid composition of lecithin, modified lecithin, PC and PE was analyzed by gas chromatography. After 48 h of reaction, the highest content of CLA incorporated into lecithin was 64.27 mol% in free-solvent system.
