Enzyme-catalyzed synthesis of structured phospholipids with conjugated linoleic acid

Authors


Abstract

Structured phospholipids were synthesized with the functional lipid conjugated linoleic acid (CLA). The lipase- and phospholipase A2-catalyzed enzymatic acidolysis reaction between phospholipids (PL) and CLA was used for fatty acid modification. Enzymatic processes were an effective way to produce structured PL. Screening of four lipases and immobilized phospholipase A2 and a combination of lipase and phospholipase showed that only Lipozyme RM IM and Lipozyme TL IM were effective in incorporation of CLA into PL. The maximum incorporation achieved by the latter enzyme was 16% with soy PL in 72 h.
