Abstract
A surface-active composition is provided which comprises phosphatidylcholine and phosphatidylethanolamine, wherein at least 3 wt. % of the phosphatide is lysophosphatidylethanolamine and wherein the hydrolysis ratio of the degree of hydrolysis of phosphatidylethanolamine and the degree of hydrolysis of phosphatidylcholine is higher than 1.7. The composition is particularly suitable for use as emulsifying agent in edible fat-containing products, especially as anti-spattering agent in, for example, margarine. The surface-active composition can be suitably prepared by fractionating vegetable lecithin with, for example, a lower alcohol, partially hydrolyzing the insoluble fraction and recombining the partially hydrolyzed insoluble fraction with the alcohol-soluble fraction.
