Hydrolysis Process of Bamboo Reed with Dilute Sulphuric Acid and Analysis of Monosaccharide Compositions

[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.
