鲤鱼脱脂方法的研究

Degreasing Methods for Common Carp Flesh

分别采用水漂洗、有机溶剂浸提、脂肪酶酶解的方法对鲤鱼鱼肉进行脱脂。试验结果表明,水漂洗法中,清水漂洗效果最优;有机溶剂浸提法中,异丙醇脱脂效果最佳,并对其采用正交试验方案对异丙醇脱脂工艺进行优化,得到最佳试验条件是:脱水时间30 m in,脱脂时间110 m in,温度为75℃,溶剂添加量为50 g;脂肪酶脱脂试验得出最佳条件是加酶量40 U/m l,酶作用时间50 m in。3种方法中,脂肪酶脱脂效果最佳。

Washing, organic solvent extraction, and alkaline lipase hydrolysis were used to remove fat mon carp （Cyprinus carpio L. ） flesh. The results showed that the alkaline water washing had the best queous solution washing. In organic solvent extraction, isopropyl alcohol was the best organic solvent. from comeffect in a- Designing orthogonal test for optimization of the process of isopropyl alcohol degreasing showed that the optimal experiment conditions were as follows： dehydration for 30 rain, degreasing period for 110 min, organic solvent quantity of 50 g at 75℃. Alkaline lipase experiment showed that optimum conditions were as follows： alkaline lipase added at a dose of 40 U/ml, degreasing period for 50 min. The degreasing effect of alkaline lipase is the best compared among these results of experiments.
