【摘要】 初步探讨了利用浸提法提取菊糖的工艺条件。其最佳的工艺条件是:用2.5%Na2SO3护色30 min,然后在100℃下提取45min。提取液用H2O2进行脱色的条件为:脱色温度为80℃,时间为0.5 h,H2O2的体积分数为3%,pH值为8.5。更多还原

【Abstract】 The experiment were designed to find out the appropriate conditions for extracting inulin from halianths tuber with water.The results show that the appropriate temperature of water and the soaking time are respectively 100 ℃ and 45 min.Before extraction step,it is necessary and effective to immerse the halianghus tuber in the solution of 2.5% Na₂SO₃ for 30 mins on the purpose of perserving its color.To denude pigment of the extracted solution,the best technology is to add 3.0% H₂O₂ to the solution and adjust the pH to 8.5 and keep the temperature at 80 ℃ for 30 mins.更多还原
