A process for preparation of carotenoid formulation useful for coloration of fish products

A process for preparation of carotenoid formulation useful for coloration of fish products by .extracting the carotenoids from homogenized crustacean waste using a mixture of isopropylalcohol and hexane in a ratio of about 1:1, washing the solvent extract with 1% saline to remove the isopropyl alcohol, adding starch as a carrier to the carotenoid extract in hexane in a proportion of 12-17% of the weight of the crustaceans wasteremoving hexane by evaporation at a temperature ranging 50-60°C to obtain the carotenoid formulation.
