【中文摘要】 以液体深层培养的食用菌新鲜菌丝体为原料 ,使用均匀正交设计的实验方法 ,优化了食用菌多糖提取最佳工艺。实验结果表明 :在鲜菌丝密度为 10 0～ 2 5 0mg/ml范围内、超声波破壁时间为 12min、热水浸提时间为 4h、提取温度为 70℃时 ,鲜多糖提得率为 2 6 0 9%。
【英文摘要】 The optimization study of polysaccharide extraction from fresh mycelia of edible fungi prepared by liquid submerged-culture were studied.The results were as follows:when the density of mycelia were at the range of 100～250 mg/ml(wet weight),the time of ultrasonic treatment were 12 min,and the extracting time were 4h at 70℃ the extraction rate of polysaccharide were 2.609%(wet weight)
