Astaxanthin is a ketone or carotenoid, pink in color, fat-soluble, insoluble in water and soluble in organic solvents. It widely exists in the biological world, especially in the feathers of aquatic animals such as shrimp, crab, fish and birds, and plays a role in color rendering. Astaxanthin is a non-vitamin A source carotenoid, which cannot be converted into vitamin A in animals. Astaxanthin is a fat-soluble and water-soluble pigment, which exists in shrimp, crab, salmon, algae and other marine organisms. The human body cannot synthesize astaxanthin itself. It is the strongest antioxidant in nature. Its antioxidant activity is 550 times that of vitamin E and 10 times that of β-carotene, so it is called the "king of antioxidants".
Astaxanthin is a chain breaking antioxidant with extremely strong antioxidant capacity, which can remove NO2, sulfide, disulfide, etc., also can reduce lipid peroxidation, and effectively inhibit the lipid peroxidation astaxanthin caused by free radicals. It is reported that this product has many physiological effects, such as inhibiting tumor occurrence, enhancing immunity, eliminating free radicals in the body, etc. It has a good therapeutic effect on skin cancer caused by ultraviolet rays, and also has a preventive effect on eye diseases caused by diabetes. It has broad application prospects in health care products, medicine, cosmetics, food additives, aquaculture, etc.
1. Food and health food
Astaxanthin has been used as a food additive in the coloring, preservation and nutrition of food abroad. Astaxanthin is fat-soluble, has bright red color and strong antioxidant properties. It has both coloring and fresh-keeping effects on foods, especially those with more lipids. In Japan, the red oil containing astaxanthin has been applied for patents in the pickling of vegetables, seaweed and fruits, and also for the coloring of beverages, noodles and condiments. Foreign countries have already carried out research on the synthesis of human health products using astaxanthin, and developed health products containing astaxanthin in view of its efficacy in strengthening the immune system function, anti-cancer, protecting the retina from ultraviolet radiation and light oxidation, anti-inflammatory, and preventing the oxidative damage of low density lipoprotein (LDL) - cholesterol in blood.
2. Drugs
Astaxanthin can be used as a drug to prevent oxidative tissue damage by taking advantage of its antioxidant and immuno-promoting effects. Studies have shown that astaxanthin can protect the ability of the nervous system, especially the brain and spine, through the blood-brain barrier, and can effectively treat ischemic reperfusion injury, spinal cord injury, Parkinson's syndrome, Alzheimer's syndrome and other central nervous system injuries; It can effectively prevent the oxidation of retina and the damage of photoreceptor cells and improve the function of retina. This research result has been patented.
3. Feed industry
The largest market of astaxanthin is in the feed industry. It can be used as a feed additive mainly for fish (salmon, sturgeon, rainbow trout, sea bream, etc.), crustaceans and poultry such as shrimp and crab. Astaxanthin, as a colorant for aquaculture animals, can make aquatic animals present bright colors and make them more ornamental; Adding astaxanthin to poultry feed can increase the content of egg yolk pigment; It can also improve the laying rate of hens and promote the health of laying hens. Astaxanthin has the same function in the prevention and treatment of fish, shrimp, crab and poultry diseases as it has for human beings. It can improve immunity and survival rate, and plays an important role in its normal growth and healthy breeding, and improve survival and reproduction rate. Astaxanthin can also increase the flavor of fish, which can be directly used as a precursor compound to form the flavor of salmon food, and can also promote the conversion of fatty acids or other lipid precursors into salmon flavor compounds.
4. Cosmetics
As a new type of cosmetics raw material, astaxanthin is widely used in creams, emulsions, lip balm, skin care products and other cosmetics with its excellent properties. Especially in the field of advanced cosmetics, natural astaxanthin, with its unique molecular structure, can effectively quench the free radicals caused by ultraviolet rays, prevent skin photoaging, reduce UVA and UVB damage to skin, prevent skin cancer, delay cell aging, reduce skin wrinkles, reduce melanin deposition, reduce freckles, maintain moisture, and make skin more elastic, tensile and moist. Japan has a patent for the use of astaxanthin in the production of cosmetics.
