摘要
In this study, with Jiuzihe poria as the main raw material, the effect of alkali concentration, extraction time and solid-liquid ratio on the extraction rate of alkali-soluble polysaccharide was investigated, and the processing technology was optimized with orthogonal experiment. The results showed that the optimum extraction process for alkali-soluble polysacchadde from poria was as follows： solid-liquid ratio of 1：50, alkali concentration of 0.5 mol/L, and extraction time of 8 h.
以九资河茯苓为主要原料,用稀碱浸提法提取茯苓多糖,研究了碱提浓度、碱提时间以及料液比等提取条件对茯苓碱溶性多糖提取率的影响,并通过正交实验对加工工艺进行了优化。结果表明,茯苓碱溶性多糖的最佳提取工艺为:料液比1:50、碱提浓度0.5 mol/L、提取时间8 h。
