摘要
以NaOH为浸泡剂,探讨了料液比、pH、浸泡时间、浸泡温度对淀粉提取率的影响,并用正交试验确定了白芷淀粉提取的最佳工艺。结果表明:淀粉提取的最适宜的提取工艺条件为料液比1:6,NaOH浸提液的pH9.0,浸泡时间6h,浸泡温度30℃。在此工艺条件下,淀粉的提取率为84.56%。
The effects of ratio of Angelica dahurica sample to water, pH, extracting time and temperature on Angelica dahurica starch extraction ratio were investigated using sodium hyroxide solution as extracting reagent. The optimal conditions for Angelica dahurica starch extraction were confirmed through orthogonal test as follows： pH 9.0, ratio of sample to water 1：6, extracting time 6 h, and extracting temperature 30 ℃. With these optimal conditions, the extraction rate of the Angelica dahurica starch was 84.56%.
