Astaxanthin
Astaxanthin is a kind of ketone or carotenoid, pink in color, fat-soluble, insoluble in water, and soluble in organic solvents. Also known as astaxanthin.
A red carotenoid found in the shells of river crayfish, oysters, salmon and other aquatic animals. The chemical name is 3,3'-dihydroxy-4,4'-diketo-β,β'-carotene. In the body, it can be combined with protein to show cyan and blue.
effect:
Especially the feathers of aquatic animals such as shrimps, crabs, fish and birds play a role in color development.
Astaxanthin is a chain-scission antioxidant. It has strong antioxidant capacity, can remove nitrogen dioxide, sulfide, disulfide, etc., can also reduce lipid peroxidation, and effectively inhibit the lipid peroxidation of astaxanthin caused by free radicals.
It has various physiological effects such as inhibiting tumor occurrence, enhancing immunity, removing free radicals in the body, etc. It has a good therapeutic effect on skin cancer caused by ultraviolet rays, and has a preventive effect on eye diseases caused by diabetes. It is used in health care products, medicine, cosmetics, Food additives and aquaculture have broad application prospects.
In addition to obtaining astaxanthin by biological extraction, it can also be produced by chemical synthesis, algae, bacteria, and yeast. In addition, the application of DNA recombination technology to construct high-yield astaxanthin genetic engineering is also under study.
