以“123小苹果”渣为原料，采用碱性过氧化氢法提取半纤维素多糖，通过单因素试验及正交试验确定H2O2浓度、溶液pH、提取时间和提取温度对木聚糖提取率的影响，从而得出最佳提取工艺条件。结果表明，H2O2浓度为2.0%、溶液pH 12.0、提取时间6 h和提取温度50℃，提取率可以达到30%以上。%Hemicellulose polysaccharides were extracted from apple pomace by alkaline hydrogen peroxide method. Single factor test and orthogonal test were used to determine the optimum extraction conditions. The re-sults showed that the extraction buffer containing 2.0%hydrogen peroxide, pH12.0, 6 h of extraction time and extraction temperature 50℃. Extraction rate could be up to 30%.
