Abstract

The invention provides a preparation method of an arachidonic acid (ARA) emulsion. The preparation method comprises the steps as follows: (1) performing mortierella alpina fermentation; (2) performingfilter pressing on a fermentation broth by a plate-frame filter press to obtain hypha, then, cleaning the hypha, and crushing a filter cake formed by the hypha; (3) adding water after crushing, and performing enzymolysis treatment by complex bio-enzyme, and keeping high-speed stirring in the enzymolysis process to prevent agglomeration; and (4) after enzymolysis treatment, shearing an enzymatic hydrolysate by a high-speed shearing head at high speed, and carrying out homogenization to obtain the ARA emulsion. The emulsion rich in ARA is obtained by the preparation method directly, the emulsion can be directly used as a feed raw material or a feed additive after spray drying, or ARA oil can be directly extracted after specific treatment of the emulsion, the risk of loss of the ARA due to high-temperature oxidation in the hypha drying process after crushing in an original traditional process is reduced, and the content and quality of the ARA are further guaranteed.

Description

technical field [0001] The invention relates to the technical field of arachidonic acid preparation, in particular to a method for preparing an arachidonic acid emulsion. Background technique [0002] Arachidonic acid (ARA) is an all-cis-5,8,11,14-eicosatetraenoic acid, which is an unsaturated fatty acid, which contains four carbon-carbon double bonds and one carbon-oxygen double bond. Higher unsaturated fatty acids. Widely distributed in the animal kingdom, a small amount exists in a certain species of glycerides, and can also be found in glycerophospholipids. It can be synthesized from linoleic acid in the human body. As a component of breast milk, ARA is necessary for the growth of infants in terms of neurophysiology and neurology. Because the synthesis efficiency of arachidonic acid in infants is very low, the synthesis amount is not enough to meet the needs of physical development, so it must Get extra from food. [0003] Substances rich in ARA are also used as feed ...
