Astaxanthin(Aquaculture)

Description

Astaxanthin is a chain-breaking antioxidant. It has a strong antioxidant capacity, can remove nitrogen dioxide, sulfide, disulfide, etc., can also reduce lipid peroxidation, and effectively inhibit lipid peroxidation caused by free radicals. At the same time, it has various physiological effects such as inhibiting tumor occurrence, enhancing immunity, and eliminating free radicals in the body. 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, It has broad application prospects in cosmetics, food additives and aquaculture.

Applications

Astaxanthin is bright red and has strong pigmentation ability. As a functional pigment, fish and poultry can absorb and accumulate astaxanthin better than other carotenoids such as canthaxanthin, lutein and zeaxanthin Much more effective.

Astaxanthin is mainly used in the feed industry, and can be used as a feed additive for abalone, sturgeon, salmon, rainbow trout, red sea bream, crustaceans, ornamental fish, various poultry, and pigs. Its main functions are:

(1) As a natural pigment to increase nutrition and commodity value. The astaxanthin added to the feed accumulates in the body of fish and crustaceans, making the adults red, bright in color and rich in nutrients, and its price is many times higher than that of ordinary adults. After meat poultry are fed with astaxanthin-added feed, the amount of egg yolk increases, and the skin, feet, and beak appear golden yellow, which greatly improves the nutrition and commodity value of poultry eggs and meat. Eating these products is beneficial to human health.

(2) As a natural hormone to improve reproductive ability. Astaxanthin can be used as a natural hormone to promote the fertilization of fish eggs, reduce the mortality of embryos, promote individual growth, increase maturation speed and fecundity.

(3) Improve health status as an immune enhancer. Astaxanthin is stronger than β-carotenoids in terms of anti-oxidation and elimination of free radicals, which can promote the production of antibodies and enhance the immune function of animals.

(4) Improve skin and hair color. Adding 50 mg/kg astaxanthin to the feed of ornamental fish such as red swordtail fish, pearl mary fish and flower mary fish can effectively improve the body color of fish. Adding 15mg/kg of astaxanthin to the breeding of brown-red dogs can improve hair color and increase its ornamental value.
