【摘要】 研究了以椴木栽培的香菇为原料 ,利用超滤膜分离装置进行香菇多糖的提取分离 ,并建立了香菇多糖提取液超滤过程修正凝胶极化模型 .本工艺香菇多糖提取率可达 6 10 % ,多糖粗品含量在 90 %以上 .研究表明 ,膜分离技术在香菇多糖提取中具有很大的优越性 .更多还原

【Abstract】 Study to use the pieces of stick bringing up lentinan edodes as the raw material. The method use the ultrafiltrations separation technology equipment to carry out this experiments extraction and separation. A modified gelification model for the ultrafiltration process is also set up in the paper. The result shows that the rate of picking lentinan can reach 6 10%, and purified product with lentinan content of morethan 90%. According to this experiment that the membrane separation technology has a great superiority during the extraction of lentinan.更多还原
