摘要
研究实验室规模下微波辐照玉米芯酸水解提取木糖的影响因素,通过单因素试验和正交试验,确定最佳反应条件。结果表明:质量分数2%硫酸溶液与玉米芯比10:1(V/m)、微波功率540W条件下酸解16min,可获较高的木糖产率(16.95%)和较好的还原糖收率(37.62%)。相对于传统的蒸煮法,该方法可大大缩短反应时间、降低能耗。
An investigation was carried out to study the factors affecting the extraction of xylose from corncob by acid hydrolysis under the assistance of microwave radiation at a laboratory scale.Using one-factor-at-a-time and orthogonal array design methods,the optimal conditions for xylose extraction were determined to be 16 min hydrolysis at a H2SO4solution（2%）/corncob ratio of 10：1（V/m） when the microwave power was set at 540 W.Under these conditions,the yields of xylose and reducing sugar were 16.95% and 37.62%,respectively.Over the traditional steaming method,the optimized method showed the advantages of shorter extraction time and lower energy consumption.
