Product description

Astaxanthin is a ketone or carotenoid with a pink color, fat-soluble, insoluble in water, and soluble in solvents.It is widely present in the biological world, especially in the feathers of aquatic animals such as shrimp, crabs, fish and birds, and plays a role in color rendering.

Astaxanthin is a carotenoid that is not a source of vitamin A. It cannot be converted into Chemicalbook vitamin A in animals.Astaxanthin is a fat-soluble and water-soluble pigment that is present in shrimp, crabs, salmon, algae and other marine organisms. The human body cannot synthesize astaxanthin by 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”!

1.Artificial synthesis of astaxanthin is the end point of carotenoid synthesis. B-carotene needs to add 2 hydroxyl groups and 2 ketones to be converted into astaxanthin. Artificial chemical synthesis is more difficult.

Physiological function and function:

Astaxanthin is a kind of chain-breaking antioxidant, which has a strong antioxidant ability, can also reduce lipid peroxidation, and effectively inhibit lipid peroxidation caused by free radicals. Astaxanthin.


At present, astaxanthin is mainly used as a functional pigment and is widely used in aquaculture, food, cosmetics and other fields.
