摘　　要：采用酸液浸泡法对从蕉藕中提取淀粉的最佳工艺进行了试验研究。通过料液比、浆料pH值、浸泡时间、浸泡温度单因素实验和正交试验确定蕉藕淀粉的最佳提取工艺条件为:料液比1∶15,浆料pH 3.0,浸泡时间4 h,浸泡温度45℃。在此条件下,淀粉的产率为18.89%。A process of extracting starch from Edible Canna was studied in this paper.The optimal extraction conditions of acidolysis were gained by single experiments and orthogonal.The results showed that the optimal extraction conditions were as follows：solid-to-liquid ratio was 1∶15,pH was 3.0,extracting time was 4 h,and extracting temperature at 45 ℃.Under this optimal condition,the yield of starch was about 18.89%.
