摘　　要：以大明虾虾仁加工废弃物为原料,利用木瓜蛋白酶对其进行水解,提取虾青素.均匀试验法及回归方程分析结果表明,酶解最适条件为:温度44.5℃、pH 5.51、时间92.6 min、加酶量1.30%.该条件下,湿虾壳总类胡萝卜素释放率为63.059μg.g-1,比直接用有机溶剂提取方法释放率提高19.879%.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 earotenoids is 63.059 μg·g^-1 wet wt., which exceeds the amount extracted by organic solvent by 19. 879 percent.
