High-stability DHA algal oil preparing method

Abstract

The invention relates to a high-stability DHA algal oil preparing method and belongs to the technical field of health care products. The method aims to solve the problems of the prior art that to improve the antioxidant ability of DHA, artificially synthesized antioxidant harmful to the health of people is added, matter with odor and other micromolecule impurities can not be effectively removed during deodorization, and therefore the sensor quality, nutritive value and oxidization stability of refined DHA algal oil are affected and DHA in algal oil is lost after deodorization. According to the method, chlorococcum is activated with plant hormones so that growth of chlorococcum can be promoted and in vivo grease can be increased, then chlorococcum is mixed with natural plants for mixed fermentation, deodorization is conducted under the action of the natural plants, antioxidant ability is improved at the same time, then chlorococcum spherical cells are damaged through bacterium enzyme rich in biogas slurry, DHA algal oil is completely released through high-pressure blasting, and finally ethyl alcohol refrigeration and bentonite decoloration are conducted to obtain the high-stability DHA algal oil.

Description

technical field

[0001] The invention relates to a preparation method of high-stability DHA algae oil, which belongs to the technical field of health care products. Background technique

[0002] Docosahexaenoic acid (DHA) is an important ω-3 long-chain polyunsaturated fatty acid. Modern medicine has proved that DHA can promote the visual and intellectual development of infants and young children, and also has a positive preventive effect on cardiovascular system diseases, cancer, and inflammation. The production of DHA has a variety of sources, among which the production of DHA algae oil by microbial fermentation has the advantages of easy large-scale cultivation, high polyunsaturated fatty acid content, easy separation and purification, and good oxidation stability.

[0003] DHA has functional properties such as strengthening the brain and improving eyesight, reducing inflammation and inhibiting allergic reactions, preventing cardiovascular and cerebrovascular diseases and ...
