The Fractionation of Phosphatidylethanolamine from Soya Phospholipids

Abstract

Abstract: Soyabean phospholipids with high content of phosphatidylethanolamine were fractionated with ethanol, and optimal conditions have been determined to improve phosphatidylethanolamine (PE) enrichment. The effects of extraction time, solvent volume, ethanol concentration and temperature on the yield and PE enrichment have been described. At the condition of extraction time is 8min, phospholipids/solvent volume is 30g/L, and 100% ethanol, using calculated optimal parameters in the fractionation process led to PE enrichment from 19.8% to 62.8%.

Key words: soya lecithin, phosphatidylethanolamine, extraction process
