摘　　要：研究超声波辅助法提取平菇水溶性多糖的优化工艺。以液固比、超声时间、提取时间、提取温度为考察因素,平菇多糖浸提率为考察指标,采用4因素3水平正交试验分别研究液固比、超声时间、提取时间、提取温度对平菇多糖浸提率的影响。结果表明,平菇多糖提取的最佳工艺为液固比30∶1,超声时间60 min,提取温度100℃,提取时间60 min。在此条件下,超声波辅助法提取水溶性平菇多糖的浸提率为17.12%。The extraction technology of water soluble polysaccharide from Pleurotus ostreatus with assisted by ultrasonic dispersion is studied. The optimum process conditions by the ratio of liquid to solid, pH value of enzymolysis, enzymolysis temperature, and ultrasonic time are probed by orthogonal tests. The results show that the optimum extraction conditions of polysaccharide from Pleurotus ostreatus are as follows： the ratio of liquid to solid 30 ： 1, ultrasonic time 60 min, extracting temperature 100 ℃, extracting time 60 min. Under the above conditions, the productivity of water soluble polysaccharide from Pleurotus ostreatus assisted by ultrasonic is 17.12%.
