Abstract
Disclosed are methods of making a modified lecithin by conducting an enzymatic conversion of a naturally derived lecithin to form a modified lecithin, e.g., having an enhanced level of phosphatidylethanolamine, phosphatidylserine, or a combination thereof. Compositions prepared from the modified lecithin and use to inhibit lipid oxidation are described.
Claims7
A method of inhibiting or delaying lipid oxidation in a lipid-containing composition, comprising:
- conducting an enzymatic conversion of a naturally derived lecithin with phospholipase D in the presence of ethanolamine, serine, or a combination thereof to form a modified lecithin comprising an enhanced level phosphatidylethanolamine, phosphatidylserine, or a combination thereof;
- incorporating an effective amount of the modified lecithin into a lipid-containing composition, wherein the modified lecithin is incorporated in an amount to provide about 1000 μmol of phosphatidylethanolamine, phosphatidylserine, or a combination thereof present in the modified lecithin/kg of lipid-containing composition;
- and
- optionally further incorporating an effective amount of an additional lipid soluble antioxidant into the lipid-containing composition;
- wherein the modified lecithin comprises greater than 60 wt % of phosphatidylethanolamine, phosphatidylserine, or a combination thereof based on the total weight of phospholipids present in the modified lecithin.
