中文摘要:
      以优化火麻油酶水解条件为目的，Mucor javanicus脂肪酶作为实验用酶对火麻油进行水解研究，在反应时间12 h、反应温度45℃条件下，通过响应面实验对反应体系的水油比、酶添加量、pH进行优化，得到反应最优条件为：水油比15∶1，酶添加量952 U/g，pH 6.62。在此条件下火麻油水解率为96.50%。
英文摘要:
      Hemp seed oil was hydrolyzed by lipase Mucor javanicus. Based on the reaction time 12 h and reaction temperature 45℃, the ratio of water to oil, lipase dosage and pH were optimized by response surface methodology. The results indicated that the optimal reaction conditions were as follows：ratio of water to oil 15∶1, lipase dosage 952 U/g, pH 6.62. Under these conditions, the hydrolysis rate of hemp seed oil was 96.50%.
