PCT No. PCT/NO89/00119 Sec. 371 Date Jul. 15, 1991 Sec. 102(e) Date Jul. 15, 1991 PCT Filed Nov. 15, 1989 PCT Pub. No. WO90/05765 PCT Pub. Date May 31, 1990.A method is provided for recovering astaxanthin, astaxanthin carotenoids, astaxanthin esters, chitin and proteins from crustacean tissues containing such. The method comprises an initial extraction of crustacean tissue with boiling lye to form an alkaline extract and an extracted residue. The alkaline extract, upon cooling, forms separate layers from which can be recovered component protein, astaxanthin, astaxanthin carotenoids and astaxanthin esters. The lye extracted residue of chitin-containing such crustacean tissue is readily processed to provide chitin.
