摘要:

通过单因素以及正交试验研究水浴及超声波辅助提取相思菇子实体多糖的最佳工艺。研究结果表明:水浴提取相思菇子实体多糖的最佳方法:料液比1:60,水浴时间90min,水浴温度60℃。通过单因素试验与正交试验均得出超声波辅助提取相思菇多糖,最佳试验方案为:料液比1:140,超声时间20min,浸提液pH8.0。对两种提取法进行了比较,超声波辅助提取法优于水浴提取法。

Abstract:

The hot water and ultrasonic-assisted extraction processes of polysaccharides from "Xiangsi" mushroom were optimized respectively by single factor test and orthogonal test in this study. The results showed that the optimal hot water extraction conditions are as follows: material to liquid ratio 1:60, water temperature 60 ℃, and extraction time 90 min, and the optimal ultrasonic-assisted extraction conditions are as follows: material to liquid ratio 1:140, ultrasonic power 80 W, pH 8.0, and extraction time 20 min. The average polysaccharides contents of the "Xiangsi" mushroom extract by the two methods are 0.620% and 2.058%. The fomer is evidently interifior to the latter.
