Patent ID: 7189544

Claim:
A method of producing a hydrolyzed lecithin product, comprising hydrolyzed phospholipids, monoglycerides, and diglycerides, the method comprising (a) contacting a lecithin material, comprising phospholipids and triglycerides, in an aqueous medium, containing water and at most 5% of another water-miscible solvent, or an organic solvent medium comprising an aprotic organic solvent and sufficient water to promote hydrolysis, with a first enzyme to create a reaction mixture, said enzyme being a phospholipase or lipase which hydrolyzes said phospholipids; (b) subsequently contacting the product of step (a), in an aqueous medium or an organic solvent medium containing sufficient water to promote hydrolysis, with a second enzyme, different from said first enzyme, said second enzyme being a lipase which hydrolyzes said triglycerides; and (c) obtaining the hydrolyzed lecithin product from the reaction mixture.
