It is a compound with multiple functions, chemically named 3,3 '-dihydroxy-4,4' -diketo-β,β '-carotene,
which belongs to a kind of carotenoid.
It is a red solid powder, insoluble in water, but soluble in organic solvents
There are three main ways to obtain astaxanthin: biological extraction, chemical synthesis and production by algae, bacteria and yeast.
Biological extraction is the extraction of astaxanthin from nature, while chemical synthesis is the synthesis of astaxanthin by chemical
