Astaxanthin Powder Description

Astaxanthin is a keto carotenoid with the chemical name 3,3'-dihydroxy-4,4'-diketo-β,β'-carotene, a red solid powder, fat-soluble, insolubleAstaxanthin buy-ruikeli 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.


Astaxanthin is a chain-scission antioxidant. It has 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, removing free radicals in the body, etc., 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, Cosmetics, food additives and aquaculture have broad application prospects.

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.

RealclearBio also accept customization for Extract Ingredient, Content, Color, Solubility, Moisture, Ash, Heavy Metal, Pesticide Residue, Microorganism etc.

Physical&Chemical Properties:

The chemical name of astaxanthin is 3,3'-dihydroxy-4,4'-diketo-β,β'-carotene, and the molecular formula is C40H52O. The crystal-like astaxanthin is pink, with a melting point of 215-216°C, It is insoluble in water, fat-soluble, and easily soluble in most organic solvents such as chloroform, acetone and benzene. The conjugated double bond chain in the molecular structure of astaxanthin, as well as the unsaturated ketone group and hydroxyl group at the end of the conjugated double bond chain, can attract unpaired electrons of free radicals or provide electrons to free radicals, thereby scavenging free radicals and playing an antioxidant role

This structure also makes it easy to interact with light, heat, and oxides. After the structure is changed, it is degraded into astaxanthin, especially the effect of ultraviolet light on it. The astaxanthin will be completely destroyed after continuous irradiation for about 4 hours;

Below 70℃ and pH 4-7, astaxanthin is relatively stable; Ca2+, Mg2+, K+, Na+, Zn2+ metal ions basically have no effect on astaxanthin, Fe2+, Fe3+, Cu2+ have obvious destructive effects.

The chromophore in the molecular structure of astaxanthin has a unique absorption zone in the ultraviolet-visible region, so its crystal or solution is purple-red under visible light. Astaxanthin mainly exists in free form and esterified form. The free astaxanthin is extremely unstable and easily oxidized. Usually, the chemically synthesized astaxanthin is in the free form. Esterified astaxanthin is stable due to the fact that there is a hydroxyl group in the terminal ring structure of astaxanthin which is easy to form esters with fatty acids. Astaxanthin on the skin and shell of aquatic animals is mainly in the form of lipidation, meat and internal organs The above is mainly in free form. Astaxanthin in Rhodotorula and Haematococcus pluvialis mainly exists in esterified form. The esterified astaxanthin is divided into astaxanthin monoester and astaxanthin according to the different fatty acids that it binds. Diester After astaxanthin is esterified, its hydrophobicity is enhanced, and the diester is more lipophilic than the monoester; the esterified state of astaxanthin, or forms a complex with protein, will produce different colors.

Astaxanthin has two chiral centers, which are C-3 and C-3' of the two-terminal ring structure in the molecule. A chiral center can have two conformations. Astaxanthin's dual chiral carbon atoms C3 and C3' can exist in the form of R or S, so there are three stereoisomers, 3S, 3'S and 3R, 3' The R isomers are mirror images of each other (enantiomers), each enantiomer has the opposite optical rotation, which can rotate the flat polarized light to the left or right, 3R, 3'S have no optical rotation.

Astaxanthin is a carotenoid that is not a source of vitamin A and cannot be converted into vitamin A in animals. Natural astaxanthin is a powerful quencher of singlet oxygen. Animal experiments show that astaxanthin can remove NO2, sulfide, and disulfide, and can also reduce lipid peroxidation, effectively inhibiting lipid peroxidation caused by free radicals. At the same time, it has anti-cancer activity, can significantly affect the immune function of animals, strengthen aerobic metabolism, significantly enhance human muscle strength and tolerance, and has anti-infective activity.

Method of extracting astaxanthin from Haematococcus pluvialis:  

Step 1: Add Haematococcus pluviali powder to the oil-ethanol composite solvent, then place the head part of the flash extractor in the oil-ethanol composite solvent, start the flash extractor, break lift to obtain the mixture suspension, filter the mixture into the extract and filter slag.

Step 2: The extract will be decompressed to recover ethanol, to obtain astaxanthin extract.
