Embodiment Construction

[0057] Hereinafter, the present invention will be explained in detail.

[0058] The term "phospholipid DHA" or "phospholipid EPA" as used herein refers to a phospholipid in which DHA or EPA is attached to the 1- or 2-position of the phosphoglyceryl group. It is well known in the art that phospholipids are a class of lipids containing phosphate groups, generally having a hydrophilic head and a hydrophobic tail; The hydrophobic tail is composed of fatty acid chains. The hydrophilic head of phospholipid DHA and phospholipid EPA can be phosphatidic acid (PA), phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylglycerol (PG), phosphatidylinositol (PI) Wait.

[0059] In a first aspect, the present invention relates to a method for preparing an oil composition containing phospholipid DHA and phospholipid EPA. In the oil composition prepared according to the method of the present invention, the contents of phospholipid DHA and phospholipid EPA are respectively 9.0-...

Abstract

The invention discloses a preparation method of an Antarctic krill oil substitute. The invention provides a method for preparing an oil composition containing phospholipid DHA and phospholipid EPA and the oil composition prepared according to the method. Specifically, the present invention precisely controls the ratio of DHA and EPA in the reaction raw materials to prepare an oil composition containing phospholipid DHA and phospholipid EPA almost the same as natural Antarctic krill oil.

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 ...
