Canthaxanthin, also known as astaxanthin, with the chemical name 3,3'-Dihydroxy-β,β'-carotene-4,4'-dione.

Canthaxanthin is an important carotenoid that widely exists in organisms in nature, such as mushrooms, crustaceans, fish, and birds. It can also be mass-produced through chemical synthesis methods. In nature, some microorganisms and algae are also capable of synthesizing canthaxanthin. Due to its good coloring effect and high stability, it is often used as a colorant in foods, feeds, cosmetics, and other products. At the same time, canthaxanthin is also widely applied in the medical field because of its physiological functions. Canthaxanthin is similar to VE, astaxanthin, β-carotene, etc. in terms of the quenching effect on free radicals.
