摘　　要：以南美白对虾虾壳为材料,利用一定质量分数的NaOH溶液脱除虾壳中的蛋白质,并用凯氏定氮法、盐析法、等电点法、有机溶剂沉淀法等方法来测定出虾壳中蛋白质的脱除率与回收率。结果表明:南美白对虾虾壳中蛋白质的最优回收条件为:NaOH溶液的浓度为10%,反应温度为100℃,反应时间为0.5 h,该实验中蛋白质的脱除率为85.34%,回收率为84.8%。The shrimp shell of Pvannamei as experimental material, used a certain quality score of NaOH solution removing the protein in shrimp shell and used kjeldahl determination, salting out method, isoelectric point method, organic solvent precipitation and so on to determine the shrimp shell protein removal rate and recovery rate. The research indicated that the best recovery condition of protein in the shrimp shell of P.vannamei is the concentration of NaOH solution was 10 %, the reaction temperature is 100 ~C, the reaction time of 0.5 h, In the experiments, the protein removal rate was 85.34 % ,and the recovery was 84.8 %.
