Why astaxanthin can make salmon, shrimp, crab red?

Astaxanthin is a kind of pigment, can give the ornamental fish, salmon, shrimp and flamingo pink color. Its chemical structure is similar to that of beta carotene. Astaxanthin is a kind of carotenoids,the highest level of product of carotenoid synthesis. beta carotene, lutein, lycopene and canthaxanthin, are nothing but the intermediate product of carotenoid biosynthesis.

  Therefore,astaxanthin has the strongest antioxidant  in nature,which is caused by the nature of algae, bacteria and phytoplankton.Astaxanthin  also known as  lobster shell pigment, pink, widely exists in the biosphere, especially high content of shrimp, crab, fish, algae, yeast and bird feathers.

  Some aquatic species, including shrimp, crab, shellfish are eating the algae and plankton, then put this pigment store in the shell, and their appearance turn red. The shellfish animal  hunted by  fish (salmon, trout, Gary fish), birds (Flamingo, Zhu Lu) and chicken, duck, and then put the pigment in the skin and adipose tissue storage.

 This is the reason why salmon and other animal in red . Huazhong Agricultural University professor of China also study confirmed,red components of Natural Red duck's egg is the core of natural astaxanthin.

  Natural astaxanthin  , the strongest in the world of natural antioxidants,can removes oxygen free radicals within the cell, enhance cell regeneration capacity, to maintain body balance and decrease the accumulation of senescent cells, from the inside to protect cells and DNA health, so as to protect the skin health, promoting hair growth, anti aging, ease of movement fatigue, enhance the vitality .
