Various kinds of carotenoid forms, such as hydrophobic reddish fraction, blue and orange carotenoproteins, and lipoproteins, were isolated from EDTA soluble fraction of the exoskeleton of crayfish and kuruma prawn. The hydrophobic reddish fraction was the main carotenoid form in crustaceans. The blue carotenoprotein possessed free astaxanthin alone, while astaxanthin esters along with free astaxanthin were present in the orange carotenoprotein. Three types of lipoproteins containing both free astaxanthin and astaxanthin esters were present in the exoskeleton, although the lipoproteins were the minor carotenoid forms. The lipoproteins isolated from the exoskeleton differed from the hemolymph lipoproteins in apolipoprotein compositions. The color development of crustaceans appeared to be affected by these carotenoid forms.
