Optimization of Extraction Technology of Polysaccharide from Portabella

[Objective] The aim of the research was to seek out the optimum technology conditions for extracting polysaccharide from Portabella.[Method] With the fruiting body of fresh Portabella as materials,the effects of the factors such as extraction time,extraction temperature,the material-water ratio and extraction times on the extraction rate of polysaccharide were studied by using hot-water extraction method.[Result] Through the orthogonal test,the optimum technology conditions for extracting polysaccharide from Portabella were obtained as follows: the material-water ratio of 1∶30,extracting for 2.5 h at 90 ℃ and extracting twice.[Conclusion] The research provided theoretical basis for the development and utilization of Portabella.
