Problems solved by technology

At present, microcapsule technology has been applied to fish oil products, such as the preparation method of DHA fish oil capsules mentioned in the invention patent application document with the publication number CN1927050A, but the fish oil microcapsules produced by the prior art generally have anti-oxidant The disadvantage of weaker resistance makes its product stability not very good, thus limiting its product shelf life
At the same time, the existing main spray drying technology is difficult to control the yield of microcapsules and leads to the loss of some raw materials and waste

Abstract

The invention relates to a strong anti-oxidation DHA microcapsule. The microcapsule comprises the following components in percentage by weight: 10 to 30 percent of DHA fish oil, 0.02 to 0.2 percent ofantioxidant, 10 to 60 percent of wall material, and 5 to 30 percent of auxiliary wall material 5. The invention also relates to a method for preparing the strong anti-oxidation DHA microcapsule. On the basis of the prior process, the microcapsule is prepared by adding the antioxidant to oil phase and water phase respectively and performing emulsification, high-pressure homogenization, improved spray granulation and cold-air boiling-drying. The newly added antioxidant can produce better anti-oxidation effects and greatly improve the oxidation stability of the DHA microcapsule so as to prolongthe shelf life of products, and the improved spray granulation and the cold-air boiling-drying process can increase the yield of the DHA microcapsule. The DHA microcapsule can be used in the fields ofmedicines, foods, beverages and the like.

Description

technical field [0001] The invention relates to a preparation and a preparation method thereof, in particular to a strong antioxidant DHA microcapsule and a preparation method thereof. Background technique [0002] DHA (docosahexaenoic acid) is an important lipid component of cell membranes, retinas, and brains. It plays an important role in the formation of cranial nerves, maintaining the normal function of cranial nerves, and delaying the decline of cranial nerves; the metabolite of EPA Eicosanic acid derivatives can effectively regulate the synthesis of arachidonic acid, prostaglandins, leukotrienes and other biologically active substances, so as to prevent and treat cardiovascular and cerebrovascular diseases, inflammation, diseases of the reproductive system and enhance the body's autoimmunity. [0003] But DHA and EPA are very easily oxidized by oxygen in the air, which brings certain troubles to their reprocessing and preservation. Encapsulation of DHA fish oil with ...
