Astaxanthin is a kind of keto carotenoid, whose chemical name is 3,3'-dihydroxy-4,4'-diketo-β,β'-carotene, red powder, fat-soluble, insoluble in water, soluble in organic solvents. It is widely present in the biological world, especially in the feathers of aquatic animals such as shrimps, crabs, fish and birds, and plays a role in color development. 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.
In recent years, as the important physiological functions and huge economic value of astaxanthin have been gradually recognized by people, researches on the functional properties of astaxanthin supplement is increasing at home and abroad, especially in anti-oxidation, anti-cancer, anti-cancer, enhancement of immunity, and anti-cancer. High blood pressure, prevention of cardiovascular disease, protection of ultraviolet radiation, etc.
Astaxanthin is a chain-breaking antioxidant with a strong antioxidant effect. Its powerful antioxidant activity is due to its ability to stabilize the membrane structure, reduce membrane permeability, limit the entry of peroxide promoters into the cell, and protect important molecules in the cell from oxidative damage. At the same time, astaxanthin is a potential pro-oxidant, which can induce oxidative stress, inhibit lipid peroxidation, protect cells and DNA from oxidative damage, and enable cells to effectively perform metabolism, thereby reducing atherosclerosis.
Studies have found that astaxanthin has the strongest quenching ability, and its ability to quench molecular oxygen is higher than β-carotene, vitamin E, α-carotene, lutein and lycopene with the same structure. In addition, experiments have shown that astaxanthin supplements can increase antioxidant enzyme activity and protein expression. Different doses of astaxanthin can significantly increase the protein expression of peroxyhydrogenase and superoxide dismutase in animal cells, and its biological activity also has Significantly improved, and these substances play a better antioxidant effect in the body.
Carotenoids are the main pigments in aquatic animals, and astaxanthin accounts for most of the carotenoids in aquatic animals. Therefore, it can be said that astaxanthin is the main pigment in aquatic animals and has a strong pigment deposition ability. . Experiments show that adding astaxanthin to the feed not only makes the fish's epidermal phosphorous yellow but also increases the content of astaxanthin in the muscle.
- Application in anti-aging functional food
Body senescence is mainly caused by a large number of free radicals produced in the chain oxidation reaction of mitochondria. If it is not cleared in time, it will cause mitochondrial oxidative damage and accelerate the aging of body cells. Astaxanthin has strong antioxidant activity and can effectively scavenge oxygen free radicals. Its efficiency is more than 100 times that of VE. Astaxanthin supplement not only maintains a strong antioxidant capacity, but also slows down the age-related functional decline and helps fight aging. Therefore, adding astaxanthin to functional foods will help prevent a series of diseases caused by organ aging and improve people's health.
- Application in foods that enhance immune function
Astaxanthin can significantly promote the ability of spleen cells to produce antibodies in the presence of antigens, and enhance T cells to stimulate the production of immune globulin in human blood cells. In the initial stage of antigen invasion, astaxanthin can also enhance the specific humoral immune response. Astaxanthin has the best activity of inducing cell division, can increase the production of human immunoglobulin, and has an important immunomodulatory effect. Therefore, the application of astaxanthin in healthy foods to enhance the body's immunity is an important direction for the development of astaxanthin supplement.
- Application in functional food additives
In the food industry, astaxanthin can not only be added to food as an immune enhancer, anti-aging agent and other functional ingredients but also can effectively maintain freshness, color, taste, quality, etc., as a food colorant, anti-aging agent, etc. Oxidizers, etc. It is used to keep the original nutrients of the food from being damaged or lost or to improve the sensory properties, and enhance the attractiveness of the food to consumers. It can be used for the coloring of many health products and the coloring of tablet sugar coatings and capsules. It can also be used directly in food and beverages, with both a good coloring effect and a significant quality preservation effect.
A large number of studies at home and abroad have proved that astaxanthin has potential special health effects in the human body, making astaxanthin more and more popular with people, and its development prospects are broad. With the in-depth research on the functional properties of astaxanthin supplement and the improvement of production technology, the use of astaxanthin to develop functional nutritious foods will have excellent application prospects and far-reaching development significance.
