在正己烷有机溶剂中脂肪酶能有效地催化鱼油和卵磷脂的酯交换反应 .本研究探讨了反应温度、酶活力和底物不同比等条件下对卵磷脂和鱼油中的ω- 3脂肪酸结合率的影响 .结果表明 ,当在 2 5mL的正己烷中 ,反应温度为 4 5℃ ,酶活力为 0 .8u/mL ,r(卵磷脂 )∶r(鱼油 ) =1∶ 4时 ,反应 2 4h后卵磷脂中DHA/EPA的结合率为 16 .3% . In n-hexane organic solvent, lipase can effectively catalyze the transesterification of fish oil and lecithin.In this study, the effects of reaction temperature, enzyme activity and substrate ratio on the lecithin and fish oil omega-3 fatty acid binding The results showed that when the reaction temperature was 45 ℃, the enzyme activity was 0.8u / mL and r (lecithin): r (fish oil) = 1: 4 in 25mL of n-hexane, the reaction 2 After 4h, the binding rate of DHA / EPA in lecithin was 16.3%.
