METHOD FOR PREPARING HIGH QUALITY EUPHAUSIA SUPERBA OIL WITH PHOSPHATIDYLSERINE ENRICHED OF POLYUNSATURATED DOUBLE BOND FATTY ACYL GROUP

摘要

Method for preparing high quality Euphausia superba oil with phosphatidylserine enriched of polyunsaturated double bond fatty acyl group, which includes the following steps: 1) solvent extracting Euphausia superba oil to obtain phosphatidylcholine and oils containing vitamin A, vitamin E and astaxanthin; 2) preparing aqueous phase enzyme catalyzing reaction system; 3) adding said reaction system into reactor, stirring after adding phosphatidase D continuously; 4) extracting resulting reaction liquid repeatedly, filtering and freeze drying resulting solid to obtain phosphatidylserine enriched of polyunsaturated double bond fatty acyl group; 5) mixing said phosphatidylserine enriched of polyunsaturated double bond fatty acyl group with oils of step 1) to obtain high quality Euphausia superba oil.
