果胶酶浸提菊芋菊糖的研究

对果胶酶提取菊糖的工艺进行了研究.采用正交实验设计优化提取条件,确定固液比为1:14、添加果胶酶的浓度为0.5%、处理温度45℃、pH4.0、提取时间120min为最佳的提取工艺,在此条件下,菊糖的提取率平均为11.56%,高于热水浸提的提取率.

Study on extraction of inulin from jerusalem artichoke with pectinase

Extraction of inulin with pectinase was studied.By means of orthogonal design,optimum parameters were confirmed as solid to liquid ratio 1 : 14, pectinase concentration 0.5％, extraction temperature 45℃, pH 4.0 and extraction time 120min.Under such condition,the average extracting rate of inulin was 11.56％ ,it was more than the rate with hot water.
