摘要
设计了4因素3水平正交试验研究了黑木耳多糖的提取工艺,以多糖的得率为指标筛选出了黑木耳多糖的最佳提取工艺:微波强度100%、提取温度100℃、提取时间90min、液料比20。提取得到的多糖经脱脂脱蛋白后,以多糖:可溶性淀粉:甜蜜素=1:5:0.05为配方,配制了黑木耳多糖冲剂,通过对冲剂的多糖测定表明,冲剂中的多糖以独立形式存在,未参与反应,可充分发挥黑木耳的保健和调节免疫功能。
Four factors and three levels of the orthogonal experiment was designed to optimize the polysaccharide extraction. The results showed that the parameters of microwave power 100%, temperature 100 ℃, extraction time 90 min and liquid material ratio 20 was the better condition. The extracted polysaccharide after the removal of protein was prepared in the ratio of polysaccharides: soluble starch:sodium cyclamate=1:5:0.05. The content of Auricularia polytricha polysaccharide granule was measured, the results indicate that the granule would be a good functional food.
