摘要
鳀鳀一种重要的海洋渔业资源,其鱼油富含EPA(二十碳五烯酸)和DHA(二十二碳六烯酸),在食品、医药等行业具有广泛的应用价值。本研究以鳀鱼作为原料,利用双酶水解法从鳀鱼中提取鱼油,通过正交试验筛选出提取鱼油的最佳工艺条件:料液比为1∶3,加入1.75%胰蛋白酶,温度为45℃,pH 8,反应时间5 h;加入1.25%胃蛋白酶,温度为40℃,pH 2.5,反应时间3 h,鳀鱼出油率为77.55%。
Anchovy is an important marine fisheries resource,which oil is rich in EPA and DHA.It has applied widely in food,medicinal and other industry.The fish oil is extracted from anchovy by bienzyme hydrolysis.The optimum technical conditions are obtained by orthogonal experiment： solid-liquid ratio 1∶3, trypsin 1.75%,temperature 45℃,pH 8,time 5 h;pepsin 1.25%,temperature 40℃, pH 2.5,time 3 h.Under these conditions,the yield of fish oil is 77.55%.
