Title: The application of papain in astaxanthin extraction from prawn waste
Abstract: The waste of prawn has been hydrolyzed by papain for the extraction of astaxanthin.The optimal hydrolyzed conditions were determined by the results of the uniform design experimentation and the analyses of regression equation: temperature is 44.5?℃,pH?5.51、 hydrolyzed time 92.6?min、 E/S(1.30%).Under the experimental conditions used,the amount of total carotenoids is 63.059?μg·g~(-1) wet wt.,which exceeds the amount extracted by organic solvent by 19.879 percent.
