| 摘 要： | 以石灰水为浸泡剂，探讨了pH、料液比、浸泡时间、沉降时间对淀粉提取率的影响，并用正交试验确定了蕨根淀粉提取的最佳工艺。结果表明：淀粉的提取率随pH、料液比、沉降时间的增加而增加，随浸泡时间的延长而增加，当浸泡时间超过3h后，淀粉的提取率反而下降。最适宜的提取工艺条件为：pH8．0，料液比1：4，浸泡时间3h，沉降时间7h。

| Abstract: | The effects of pH, ratio of sample to water, extracting time and subsiding time on fernery starch extraction ratio were investigated using limewater as extracting reagent. The optimal technics conditions of extracting starch for fernery were confirmed through orthogonal test. The results showed that the starch extraction ratio increased with the increase of pH, ratio of sample and water, subsiding time, extracting time, but decreased when extracting time was more than 3 hours. The optimum bleaching conditions were found to be pH8.0, ratio of sample and water 1:4, extracting time 3 hours, subsiding time 7 hours, respectively. |
