摘要
以香菇多糖为研究对象,采用单因素分组实验法对香菇多糖提取工艺(热水法和微波提取法)进行了初步的探讨,比较了时间,浸取温度,浸取次数,液固比等因素对多糖提取率的影响。其中传统热水提取法的最佳工艺条件为:液固比10,加热温度45℃,加热时间5h,提取二次。微波法提取香菇多糖的最佳工艺条件:液固比10,功率40%,加热时间180s,pH值1。通过两种最佳工艺条件的结果比较可知,微波萃取法具有节能、省时、环保、操作便利且提取率高等优点。
Extracting technologies of Lentinus edodes polysaccharide of primary study are finished with a single factor in different experimental groups (hot-water and microwave-assisted method),the effects of various factors, such as extracting time, temperature,times, ratio of liquid to solid and the quan- tities of solvent et al on the producing rate of Lentinus edodes polysaccharide are compared at given conditions. The optimal conditions with traditional method are: 10 of ratio of liquid to solid, 45℃ of temperature, 5 hours of heating time ,extraction twice, with microwave-assisted method are 10 of ratio of liquid to solid, 40% of power, 180 seconds of heating time and 1 of pH. The results demonstrated that microwave-assisted method had many advantages, such as saving time, low energy consumption, favorable profiting environmental protection, easy operation and so on.
