Preparation method of euphausia superba oil substitute

Abstract

The invention discloses a preparation method of a euphausia superba oil substitute, and provides a method for preparing a fat composition containing phosphatide type DHA and phosphatide type EPA and afat composition prepared according to the method. Particularly, by accurate control over the ratio of DHA to EPA in reaction raw materials, the fat composition which contains the phosphatide type DHAand the phosphatide type EPA and is almost the same as natural euphausia superba oil is prepared.

Description

technical field [0001] The invention belongs to the field of preparing lipids by biocatalysis, and specifically relates to the preparation of an Antarctic krill oil substitute by using a biological enzyme preparation as a catalyst, and using soybean lecithin, EPA or its esterified derivatives, and DHA or its esterified derivatives as raw materials Methods. Background technique [0002] Polyunsaturated fatty acid (PUFA) refers to a class of fatty acids with not less than 18 carbon atoms and more than two double bonds; among them, the PUFA whose first double bond appears at the third position of the methyl end of the carbon chain is called n -3 polyunsaturated fatty acids. Typical examples of n-3 polyunsaturated fatty acids include docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). A large number of pharmacological and animal experiments have proved that DHA is necessary for the normal development of the retina and the normal function of the nervous system. In the ...
