| 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60 min，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50 min，活性碳用量为20 g/L，脱色率为69.13％，菊粉损失率为7．93％。 |

| Abstract: |
| 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%. |
