Abstract

The invention discloses a high-purity EPA glyceride and DHA glyceride preparation method. The method includes steps: (1) performing fish oil enzyme catalytic hydrolysis, to be specific, adding water, fish oil and glyceryl ester hydrolase into a reactor, enabling reactants to be in an emulsified state under the condition of stirring, and adjusting pH, wherein final reaction products are fatty acid and glycerin aqueous solution; (2) separating and purifying fish oil fatty oil by a film evaporator and a rectifying tower to obtain high-purity EPA and DHA; (3) synthesizing EPA glyceride from EPA and glycerin through lipase; (4) synthesizing DHA glyceride from DHA and glycerin through lipase. The method is free of chemicals such as ethyl alcohol and urea, and a production process is simple; a multistage molecular distillation separation method which fails to realize large-scale production is substituted by a rectifying tower separation method which is easy to implement large-scale production, so that production efficiency is improved, and industrial environmental pollution is abated.

Description

technical field

[0001] The invention belongs to the field of biotechnology, and in particular relates to a preparation method of high-purity EPA glyceride and DHA glyceride. Background technique

[0002] Omega-3 (Omega-3) is an important class of polyunsaturated fatty acids. Fish oil-derived EPA supplements can increase the concentration of EPA in the body. Arthritis) effective. In addition, EPA was also shown to improve the effectiveness of a drug for severe chronic psoriasis (a combination of low-dose etretinate and a corticosteroid).

[0003] In the early 21st century, foreign medical clinical research found through a series of large-scale clinical studies that the purity of Omega-3 (Omega-3), the active ingredient in fish oil, determines the efficacy of fish oil products, that is, the purity of Omega-3 in fish oil is above 85%. have clinical significance. A clinical study published in the official journal "PLEFA" of the International Society for Fatty Acids and Lipids...
