ABSTRACT:
Conversion of crude lecithin is performed by incubating the lecithin with a lipase-phospholipase mixture in a water/polyol environment. The incubation is carried out at about 40-50.degree. C. and a pH of about 7 to about 8 while stirring continuously. The reaction simultaneously produces lysolipid, lysophospholipid, monoglycerides, and diglycerides. The conversion rate of lecithin is more than 80% based on the ratio of LPC/PC (lysophosphatidylcholine/phosphatidylcholine). Calcium chloride can be added to the reaction mixture to capture released fatty acids.
