Rain raw red found astaxanthin content of 1.5% to 10%, is seen as a natural shrimp green element of “concentration”, will rain raw red found powder through a mixture of ethanol and ethyl acetate solvent extraction, after saponification, get the rain raw red found extracts, have good ability of inhibiting lipid peroxide, clear DPPH, free radicals and reduction ability.

Source of astaxanthin can be divided into natural extract (rain raw red found extraction), fermentation, yeast and other aquatic products processing (red hair) and synthetic or chemical methods, natural shrimp green element exists in the form of more than 90% in the esterification, therefore more stable, shrimp and green synthesis has a reputation for free, must be the embedding can be stable, only 25% of the sinistral structure, oxidation resistance and only a quarter of the natural, biological absorption effect is poor.

Astaxanthin has many USES. As feed, it can improve the color of cultured fish, improve immunity, improve oviposition activity, adjust the color of eggs, improve oviposition rate, and inhibit cow mastitis.In terms of health care, astaxanthin can be used as functional pigment to improve immune function and hair. Its antioxidant capacity is 6000 times that of vitamin, 800 times that of coenzyme Q10 and 3,100 times that of nattokinase. It is also the only carotene that can pass the blood-brain barrier.

Currently, the main specifications of the extracts from hyetococcosis are 1%-5% astaxanthin HPLC, 10%-12% astaxanthin oil, water-soluble astaxanthin, astaxanthin water-soluble powder, and astaxanthin aqueous solution (as an antioxidant in liquid or solid drinks).
