固体发酵紫芝菌丝体水溶性多糖的提取

Study on extraction of water soluble polysaccharide from Ganoderma japonicum mycelium by solid fermentation

采用热水浸提法提取紫芝水溶性多糖。选择浸提时间、温度、浸提固液比作为单因素进行梯度实验,确定其条件范围,再通过进一步的正交实验得到紫芝水溶性多糖浸提工艺的优化因素组合。

The paper studied the hot water extraction of the water-solube polysaccharides from Ganoderma. japonicum mycelium. The effects of extraction temperature 、 proportion of water volume, extraction time on extraction of water-soluble polyccharides were explored. The orthogonal design of L9(34) was applied and the optimum conditions of extraction were obtained.
