摘要：[目的]探讨竹簧碎屑的水解工艺,为其开发利用提供理论依据。[方法]以不同H2SO4浓度、反应时间、温度和液固比为因素进行正交试验,确定稀H2SO4水解竹簧的最佳工艺条件,并利用气相色谱仪分析竹簧水解液的单糖组分。[结果]稀H2SO4水解竹簧碎屑的最佳工艺条件为:稀H2SO4质量分数3.5%、反应温度100℃、反应时间2.5 h、液固比10∶1(m l/g),在此条件下戊糖得率达到72.61%。气相色谱分析结果表明,竹簧水解液中单糖组分主要以木糖,葡萄糖,阿拉伯糖和半乳糖,其含量分别为72.380%、11.673%、5.979%和3.468%。[结论]竹簧碎屑具有制备木糖或木糖醇的潜在应用前景。
[Objective]To investigate the hydrolysis process conditions and provide reference basis for the development and utilization of the bamboo reed.[Method]In order to find the optimum conditions,different concentration of sulphuric acid,reaction time,temperature and solid liquid ratio were arranged for the orthogonal experiment.The monosaccharide compositions of the hydrolyzate were analyzed by GC.[Result]The optimum conditions of the hydrolysis of the bamboo reed were as follows：3.5% concentration of dilute sulfuric acid,a reaction temperature of 100 ℃,a reaction time of 2.5 h,and a liquid-solid ratio of 1∶10（ml/g）.Under these conditions,the yield of pentose could reached 72.61%.Additionally,the detection from GC indicated that the main monosaccharide contained in the hydrolyzate of the bamboo reed were mainly xylose,glucose,arabinose and galactose,whose contents were 72.380%,11.673%,5.979% and 3.468%,respectively.[Conclusion]The bamboo reed waste has a potential application prospect in the preparation of xylose or xylitol.
