摘　　要：对龙虾加工废弃物为原料加工龙虾蛋白粉的工艺进行了研究。通过单因素试验获取脱脂最优工艺参数为:环己烷为脱脂剂、脱脂温度60℃、脱脂时间60min、液料比5:1;通过单因素与正交试验获取超声波辅助碱法提取蛋白质最优工艺参数为:超声波处理时间10min、碱液浓度0.8%、提取温度70℃、提取时间30min、液料比5:1,此条件下蛋白质提取率为78.6%。By single factor test, the technology conditions for defatting lobster processing wastes are determined as follows： cyclohexane alkyl as defatting solvent, temperature 60 ℃, time 60 min, and ratio of liquid to solid 5：1. By single factor and orthogonai tests, the optimal conditions of ultrasonic-assisted alkaline extraction of protein from the defatted lobster processing wastes are determined as follows： treatment time of ultrasonic 10 min, alkali lye concentration 0.8%, extraction temperature 70 ℃, extraction time 30 min, and ratio of material to liquid 5： 1. Under these conditions, the protein extraction rate is 78.6%.
