本研究先采用单因素试验对NaOH 浓度、温度、时间及料液比等因素对从稻壳中提取阿拉伯木聚糖的得率的主要影响规律进行深入的分析，然后通过正交设计实验来进一步优化了相关的碱提工艺。实验结果表明，在1:25 的料液比、4h的时间、80℃的温度以及0.2mol/L 的NaOH 浓度等条件之下，将获得最大的得率（24.94 %）。“,”In this study, a single factor experiment was used to conduct an in-depth analysis of the main influences of NaOHconcentration, temperature, time and material-to-liquid ratio on the yield of arabinoxylan extracted from rice husks, and then throughorthogonal design Experiments to further optimize the relevant alkaline extraction process. The experimental results show that themaximum yield (24.94%) will be obtained under the conditions of 1:25 material-to-liquid ratio, 4h time, 80°C temperature and 0.2mol/L NaOH concentration.
