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.
Claims20
A method of making a modified lecithin, comprising:
- conducting an enzymatic conversion of a naturally derived lecithin to form a modified lecithin comprising an enhanced level of phosphatidylethanolamine, phosphatidylserine, or a combination thereof.
A method of inhibiting or delaying lipid oxidation in a lipid-containing composition, comprising:
- incorporating an effective amount of a modified lecithin comprising enhanced levels of phosphatidylethanolamine, enhanced levels of phosphatidylserine, or a combination thereof into a lipid-containing composition, and optionally further incorporating an effective amount of an additional lipid soluble antioxidant into the lipid-containing composition.
A modified lecithin, comprising:
- an enhanced level of phosphatidylethanolamine, phosphatidylserine, or a combination thereof, and
- substantially the same amount of phosphatidylinositol, lyso-phospholipids, triglycerols, glycolipids, sterols, carbohydrates, tocopherols, or a combination thereof
- as compared to the amount of the same components found in a naturally derived, unmodified lecithin.
