Organic Astaxanthin

Organic 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. Astaxanthin can not only be obtained by biological extraction, but also by chemical synthesis, and can also be produced by algae, bacteria, yeast, etc. In addition, the application of DNA recombination technology to construct high-yield astaxanthin genetic engineering is also under study.

● Anti-oxidation
The important property of astaxanthin lies in its antioxidant properties, it is an excellent antioxidant. The strong antioxidant activity of astaxanthin is due to its ability to stabilize the structure of the membrane, reduce membrane permeability, and limit the entry of peroxide promoters into cells. Protects vital molecules in cells from oxidative damage. At the same time, astaxanthin may have the potential to be a pro-oxidant to induce oxidative stress. The conjugated double bond, hydroxyl group and unsaturated ketone group at the end of the conjugated double bond chain in the astaxanthin molecule, in which the hydroxyl group and the ketone group form an α-hydroxy ketone, these structures have relatively active electronic effects and can Donate electrons to free radicals or attract unpaired electrons of free radicals, effectively quenching highly oxidizing singlet reactive oxygen species and other free radicals in the environment. Studies have shown that the ability to quench reactive oxygen species increases with the increase in the number of conjugated double bonds, and astaxanthin has the strongest quenching ability, and its ability to quench molecular oxygen is better than that of β-carotene, Vitamin E, alpha-carotene, lutein and lycopene are all high. Astaxanthin integrated into the membrane system inhibits lipid peroxidation through the protection of liposomes, and can also protect cells and DNA from oxidation damage, protect intracellular proteins, enable cells to effectively metabolize, and make cells The proteins in it function better. This antioxidant effect is manifested in prolonging the time for low-density lipoprotein (LDL) to be oxidized, thereby reducing the occurrence of atherosclerosis.

● Anticancer effect
Investigations of the relationship between dietary carotenoid intake and cancer incidence or mortality found that overall cancer incidence or mortality was significantly negatively correlated with carotenoid intake. Comparing the anti-tumor activities of various carotenoids, astaxanthin has the strongest effect. The antitumor activity of astaxanthin may be related to its signal transduction between cells, the induction of xenobiotic metabolizing enzymes, and the regulation of immune responses related to tumor cells. Studies have shown that astaxanthin can inhibit the mutagenic effects caused by aflatoxin B1, benzopyrene (BaP), diethyl nitrite (DEN), nitrosamines and cyclophosphamide, and the role of astaxanthin in preventing tumors can be Acts in different stages of tumorigenesis.

● Enhance immunity
Astaxanthin can significantly enhance the body's local and systemic immunity. This immunomodulatory property combined with antioxidant properties plays an important role in preventing the occurrence and spread of diseases. Experiments have shown that carotenoids can slow down the decline in immunity caused by aging, improve the function of the body's immune organs, and enhance resistance to harsh environments. More importantly, astaxanthin can enhance the function of T cells in the body, increase the number of neutrophils and natural killer cells, and participate in the body's cellular immunity; astaxanthin can also increase the activity of B cells in the immune system and eliminate foreign invasion pathogens, by assisting in the production of antibodies and enhancing the activity of other immune components, such as promoting the production of immunoglobulins, increasing IgG (immunoglobulin G), IgA (immunoglobulin A) and IgM (immunoglobulin M) The amount of production, enhance the humoral immune response, and improve the immunity of animals.

● Coloring
Carotenoids are the main pigment substances in aquatic animals, and astaxanthin accounts for most of the carotenoids in aquatic animals, so it can be said that astaxanthin is the main pigment substance in aquatic animals. Astaxanthin is the end point of carotenoid synthesis. After entering the animal body, it can be directly stored in the tissue without modification or biochemical transformation. It has a strong pigmentation ability, making the skin and muscles of some aquatic animals look healthy and bright The color of poultry eggs and poultry's feathers, skin, feet, and necks all appear healthy golden yellow or red. Experiments have shown that adding astaxanthin to the feed not only makes the epidermis of fish turn yellow, but also increases the content of astaxanthin in the muscles.
