摘要
以银杏为原料,NaOH为浸泡剂,进行银杏淀粉提取工艺研究。探讨了碱液浓度、料液比、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银杏淀粉的最佳工艺。结果表明,银杏淀粉提取的最佳工艺条件为:碱液质量分数为0.4%,料液比1∶7,浸泡温度45℃,浸泡时间3h。在此条件下,银杏淀粉的提取率为73.5%。
The effects of NaOH concentration,the ratio of sample to water,the extracting time and the temperature on ginkgo starch extraction ratio were investigated by alkali as extracting reagent.The optimal technics conditions of extracting starch for ginkgo were confirmed through orthogonal test.The extraction procedure was as follow： the NaOH concentration 0.4%,the ratio of sample to water 1∶7,the extracting temperature 45 ℃,the extracting time 3 h.Under which,the extraction rate of ginkgo starch was 73.5%.
