| 摘 要： | 采用脂肪酶催化大豆油脱臭馏出物(SODD)中的脂肪酸进行甲酯化反应。对反应条件进行单因素试验,确定了最佳反应工艺参数。经分析初步得出脂肪酶催化法甲酯化最佳条件为:甲酯化温度45℃,甲酯化时间16h,转速180r/min,底物比0.1:1。最佳条件下脂肪酸甲酯化率达到96.2%。脂肪酶反复使用6个批次活性无明显降低。

Esterification Treatment of Soybean Oil Deodorizer Distillate in Enzymatic Reaction |
| |
| Abstract: | The transesterification of soybean oil deodorizer distillate(SODD) with methanol catalyzed by lipase is investigated.The single factor is under taken in order to get the optimal combination parameters.The process is optimized for the enzymatic transesterification of soybean oil deodorizer distillate(SODD) with methanol under following conditions:methanol:SODD is 0.1:1,catalyzed by Novozym 435 lipase at 45 ℃ for 16 h.This optimized condition applies to the transesterification of SODD with methol obtain a yield of 96.2%.The enzyme can be reused several times without significant loss of activity. |
