Abstract

Industrial shrimp waste is a promising source of protein and carotenoids. The enzymatic hydrolysis of shrimp waste is considered to be an alternative process to recover biological valuable components. We evaluated the degree of hydrolysis following the hydrolysis of shrimp waste carried on by three commercial proteases, Protamex, Flavourzyme and Alcalase. Furthermore we recovered astaxanthin from dried shrimp waste, using organic solvents and supercritical CO2. The extraction yield (μg/g) between the two employed method is here compared via a spectrophotometric analysis. Between the employed proteases, Protamex had the highest DH%. Hexane/isopropanol resulted to be the best solvent for astaxanthin extraction.
