A PROCEDURE FOR THE PRODUCTION OF ASTAXANTHIN AND RELATED CAROTENOIDS, ASTAXANTHIN ESTERS, CHITIN, PROTEINS AND MEAT FROM PLANTS, ALGAE, BACTERIA, KRILL, SHRIMPS AND OTHER CRAYFISH AND CRUSTACEA

摘要

A procedure is described for the production of astaxanthin and related carotenoids, astaxanthin esters, chitin, proteins and meat from plants, algae, bacteria, krill, shrimps and other crayfish and crustacea by extraction in boiling lye. The residue from the extraction is dried and dissolved in anhydride formic acid or another concentrated strong acid, filtered, then the filtrate has water added so that the purified chitin can be precipitated. Astaxanthin and related carotenoids, astaxanthin esters, chitin and proteins are removed from the extract either by acid precipitation or by cooling, removal and subsequent phase separation and purification.
