摘　　要：以普那菊苣为原料，对菊苣菊粉提取、纯化工艺进行了优化研究。结果表明，菊粉提取的最佳工艺条件为：原料为粉状，温度85℃，固液比为1：30，提取时间为60min，菊粉的提取率达58．58％。纯化时石灰乳脱蛋白的最佳处理温度为70～80℃。提取液最佳脱色工艺条件为：脱色温度70℃，脱色时间50min，活性碳用量为20g／L，脱色率为69．13％，菊粉损失率为7．93％。Conditions of the extraction and purification of inulin from Puna chicory （Cichorium intybus L. ） root were optimized by orthogonal experiment in this paper. The results showed as follows：The optimum conditions for the extraction process is temperature 85 ℃ ,water ratio 1 ： 30 and time 60 min;The extraction rate of inulin from Puna chicory （C. intybus L. ） root could achieve 58.58% ;The deprotein of crude inulin used slack lime in temperature 70-80 ℃ ;The decolored optimal parameters were in temperature 70 ℃ and active carbon dosage 20 g/L for 50 min;and the rate of decolor could reach 69.13% and the loss rate of inulin was 7.93 %.
