摘要
研究了菊芋中菊糖的提取与纯化,确定了菊芋片干燥方法为60℃烘箱热风烘干。选择提取温度、提取时间、料液比、提取次数进行单因素试验,确定条件范围,再采用正交试验优化提取条件,得到菊芋中菊糖提取最佳工艺条件为温度70℃,提取时间70min,料液比1:30,提取次数2次,菊糖得率可达52.80%。并确定了石灰乳法脱蛋白最佳处理条件为水浴温度70℃~80℃,水浴时间60min-90min,大孔吸附树脂S.8的脱色素效果最好,菊糖损失率较低。
Study that the extraction and purification of jerusalem artichoke. First, the drying method of the artichoke slices that was being dried in the oven by hot air at 60 ℃ was indicated. And the extraction temperature, the extraction time, the solid to liquid ratio, the extraction times were selected for the singlefactor test. Second, the range of conditions was determined, the extraction conditions were optimized by orthogonal experiment, the optimal conditions of the inulin extraction from jerusalem artichoke were obtained, the extraction temperature was 70 ℃, the extraction time was 70 min, the solid to liquid ratio was 1 : 30, the extraction times was two, and the inulin yield rate was up to 52.80%. Others, the best treatment conditions of protein removal by milk of lime were determined, water bath temperature was between 70 ℃ and 80 ℃, water bath time was from 60 min to 90 min, with the best effect of depigmentation by macroporous adsorptive resins S-8 and the low rate of inulin loss.
