Abstract
The present invention relates to a high-LPI lysolecithin and methods related to the same. The high-LPI product is produced through the reaction of lecithin with a unique method using solvent, buffer/water, and phospholipase. Using the current production method, LPI content increased from 1.4% to 3.2-13.1% using regular soy lecithin as the starting material and LPC, LPE and LPA contents also increased from 5.1%, 2.0%, 1.0% to 15.8%, 14.6% and 4.4% respectively.
Claims22
A method of producing high-LPI lysolecithin wherein resulting lysolecithin comprises at least 2.5% by weight LPI, wherein the method comprises the steps of:
- mixing a source of lecithin with an organic solvent, at least one buffer or water, and a phospholipase to form a reaction mixture;
- heating the reaction mixture to 40 to 65° C. for about 0.5 to 5 hours;
- cooling the reaction mixture to 40° C. or below to separate the high-LPI lysolecithin from the reaction mixture;
- and
- collecting the high-LPI lysolecithin.
