摘　　要：淡水鱼类加工过程中会产生大量废弃物如内脏等,为充分回收利用其中的鱼油成分,应用酶解法从鲢鱼内脏中提取鱼油。以鱼油提取率为指标,选择合适的蛋白酶,研究了酶解工艺条件对提取率的影响。结果表明,使用中性蛋白酶,比较容易提取鲢鱼内脏鱼油。最佳的酶解条件为液固比0.8∶1、酶添加量1.67%、pH值7.8、酶解温度55℃时酶解时间3 h,鱼油提取率为17.2%。A great deal of by-products in fish processing such as viscera were generated. In order to recover fish oil from fish wastes, the process parameters affected on the extraction rate of fish oil were studied regarding the extraction rate of fish oil as the index and choosing the suitable protease. The optimal process parameters were that the temperature of neutral protease was 55~C , the amount of neutral protease 1.67%,the substrate concentrate 0.8,the hydrolysis time 3h,the hydrolysis pH 7.8 .Under these conditions, the extraction rate of fish oil was 17.2%.
