利用响应曲面法研究超声波辅助提取红菇子实体多糖的工艺。在单因素试验基础上,选择了提取功率、时间和温度为自变量,多糖得率为响应值,建立了超声提取工艺条件多元二次模型,探讨了各因素及其交互作用对多糖提取的影响,确定子实体多糖超声波辅助提取工艺的最佳条件为:提取功率380 W、时间7 min 52 s、温度44℃、液料比40︰1(mL/g)和料液pH8,在此条件下提取的多糖得率为5.69%。
Study on Ultrasonic Assisted Extraction of Polysaccharide from Fructus. On the basis of single factor experiments, the extraction power, time and temperature were chosen as independent variables, and the polysaccharide yield was the response value. The multivariate quadratic model of ultrasonic extraction process conditions was established, and the influence of various factors and their interaction on the extraction of polysaccharides , The optimal conditions for ultrasonic assisted extraction of fructus polysaccharides were as follows: extraction power 380 W, time 7 min 52 s, temperature 44 ℃, liquid-to-liquid ratio 40︰1 (mL / g) and feed solution pH8 The polysaccharide yield was 5.69%.
