Pentosan is a non-starch polysaccharide, which has a good application prospect in food, pharmaceutical and other industries. In this paper, cheap and easily available reeds are used as experimental materials, sodium hydroxide extraction is used, and the pentosan content in the product is determined by Duffau distillation. The effect of temperature on the extraction of water-soluble pentosan was studied, and the effect of boiling water bath time on water-soluble pentosan was studied. Through the analysis of the results of orthogonal experiments, the optimum technological conditions for the extraction of water-insoluble pentosan in the research area were determined. The experimental results show that the optimal water bath time for the extraction of water-soluble pentosan is 2h, and the effect of different factors on the extraction of water-soluble pentosan is in order of NaOH concentration, water bath temperature, and water bath time.
