摘要
以小麦麸皮为原料,用超声处理结合蒸煮法制备木聚糖,分别研究了不同料液比、超声时间、超声温度、蒸煮时间、蒸煮温度对木聚糖提取率的影响,以木聚糖提取率为响应值,应用响应面分析法(RSA)对木聚糖提取工艺进行了优化,确定最优工艺参数为:料液比1∶20,超声时间20min,蒸煮温度100℃,蒸煮时间2h。在此条件下木聚糖的提取率为59.87%。
The experiment took wheat bran bile as the raw material,used the ultrasonic and steaming technology to extract the xylan. Studied the influence of the ratio of liquid to solid. Ultrasonic time,the steaming temperature,the steaming time to extract the xylan,and used response surface analysis （RSA） to determine the optimal process parameters. The result shows that when set the ratio of liquid to solid at 1 ∶20, ultrasonic processing time at 20 min, steaming temperature at 100 ℃,steaming time at 2 h,the extraction ratio of xylan is 59.87%.
