摘要
以小麦麸皮为原料,研究了在超声波辅助条件下利用木聚糖酶酶解小麦麸皮制备阿魏酸的最佳工艺条件。结果表明,通过正交试验确定超声波辅助酶法提取阿魏酸的最佳工艺参数为:超声功率150 W、超声时间20 min、酶解时间45 min、料液比1∶10、酶解pH5.0、加酶量1.2%、酶解温度50℃,在此反应条件下的阿魏酸的提取率为94.48%。
The enzymolysis with optimum technological conditions for preparing ferulic acid from xylanase were studied. As seen from the results, the optimum tracting ferulic acid by ultrasonic-assisted enzymatic method determined through wheat barn by ultrasonic-assisted technological parameters for exorthogonal test were showed as follows: ultrasonic power 150 W, ultrasonic time 20 min, enzymolysis time 45 min, ratio of material to liquid 10 : 1, enzymolysis pH 5.0, additive amount of enzyme 1.2% and enzymolysis temperature 50℃. Under these reaction conditions, the extraction rate of ferulic acid was 94.48%.
