摘　　要：研究了以竹屑为原料进行水解生产木糖。其制备工艺包括原料的预处理、酸水解、中和、脱色和浓缩。成品经过薄层层析和旋光测定等鉴定确定为木糖。该制备工艺的得率为理论得率的80%。This work deals with preparation of crude xylose by hydrolyzing bamboo chips, which is a novel raw material applied to xylose production. The preparation process consists of pretreatment, acid hydrolysis, neutralization , decoloration and concentration.The product xylose is identified by silica gel TLC, optical activity measurement and other approval tests. The yield of the obtained xylose is 80 % of the theoretical amount.
