Abstract

The invention discloses a preparation method of an astaxanthin micro nanometer solid steady-state preparation capable of being dispersed through cold water. A natural astaxanthin extract is used as a raw material, through technologies of low-temperature treatment, low-energy self micro emulsification, microencapsulation, drying, granulation and embedding twice and the like, the astaxanthin micro nanometer solid steady-state preparation capable of being dispersed through cold water can be prepared. The prepared astaxanthin solid preparation powder disclosed by the invention is dried, good in flow property, and good in product processing and storing stability; and besides, the bioavailability of astaxanthin is significantly improved. The method is simple in preparation technology, mild in condition, and suitable for industrialized popularization and application. Through the adoption of the technique of the preparation method disclosed by the invention, the astaxanthin can be steadily applied in the field of aqueous-phase medium foods, solid medium foods, various premix food, daily chemical articles for use, medicines and the like, the application field of the astaxanthin is greatly widened, the pluralism of products is greatly widened, and the market potential is tremendous.

Description

technical field [0001] The invention belongs to the technical field of preparation of active substance preparations, in particular to an astaxanthin micro-nano solid preparation. Background technique [0002] Astaxanthin is the strongest natural antioxidant found in nature so far, its antioxidant capacity is 1000 times that of natural VE, 10 times that of β-carotene, 17 times that of grape seed oil, anthocyanin OPC 150 times that of coenzyme Q10, and 60 times that of coenzyme Q10. More and more research results show that astaxanthin has a variety of physiological activities, such as anti-aging, anti-tumor, prevention of cardiovascular and cerebrovascular diseases, liver protection, anti-diabetes, anti-inflammation, improvement of motor function, and astaxanthin It is the only carotenoid found so far that can penetrate the blood-brain and blood-retinal barriers, and can have a positive impact on the central nervous system and brain function. Therefore, adding astaxanthin to...
