Astaxanthin CAS NO.472-61-7

Description

Astaxanthin, also known as shrimp flavin and shrimp xanthin, is a ketone or carotenoid. It is pink in color, fat soluble, insoluble in water and soluble in organic solvents. It widely exists in shrimp, crab, fish, birds, some algae, fungi and other organisms. As a non vitamin a carotenoid, astaxanthin can not be transformed into vitamin A in animals, but it has the same antioxidant effect as carotenoids. It has a higher ability to quench singlet oxygen and capture free radicals β- Carotene is more than 10 times higher and more than 100 times stronger than vitamin E. people also call it "super vitamin E". Astaxanthin has been widely recognized for its antioxidant, coloring and enhancing immunity.

Applications

1. Mainly used as feed additive for fish (salmon, sturgeon, rainbow trout, red snapper, etc.), crustaceans such as shrimp and crab and poultry.
2. As a colorant for aquaculture animals, can make aquatic animals show bright color and make them more ornamental;
3. Adding astaxanthin to poultry feed can increase the content of egg yolk pigment;
4. Improve the laying rate of hens and promote the health of laying hens.
5. Astaxanthin has the same function as human in the prevention and treatment of fish, shrimp, crab and poultry diseases. It can improve immunity and survival rate. It plays an important role in its normal growth, healthy breeding, survival rate 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.

Storage

Store in dry conditions below 30º C, away from sunlight. After opening, it should be stored in a separate package.

Natural astaxanthin also known as astacin, is a kind of precious health ingredients, is used for development to enhance immunity, anti-oxidation, anti-inflammatory, eyes and brain health, regulating blood lipids and other natural and healthy products. At present, the main used as a raw material for human health food and medicine; aquaculture (currently the main salmon, trout and salmon), poultry feed additive and additives of cosmetics.
It can significantly improve the body's immunity, because of its non-specific combination with skeletal muscle, can effectively remove the free radicals which are generated by the movement of the muscle cells, strengthen aerobic metabolism, so it has a significant anti fatigue effect.
It is only the carotenoids through blood brain barrier, with true anti-aging effect and effective antioxidant is the basis of all beauty activities. Owing to its powerful antioxidant, It can effectively wrinkle anti-aging, sunscreen whitening and except for chloasma caused by age. In the prevention and treatment for age related macular degeneration and improvement of retinal function, it has good effects. All of the above can clearly be confirmed in the United States.
The stability and antioxidant activity of synthetic astaxanthin also are lower than natural astaxanthin. Because of the hydroxyl (-OH) at ends of the molecule, astaxanthin can be esterification, resulting in not the same of its stability. More than 90% of natural astaxanthin is exist in ester form, and therefore more stable. Synthesic astaxanthin is the free state, therefore, the stability is not the same, must be embedded in order to stabilize. Because Left lateral structure of synthesic astaxanthin was only about 1/4, so it is only natural antioxidant of 1/4.
