摘要：

以活性炭为脱色剂，研究影响仙草胶提取液脱色效果的因素及条件，优化了脱色工艺参数。试验结果表明，活性炭对仙草胶提取液的最佳脱色条件为：活性炭用量2.5%，温度60 ℃，时间50 min，在此条件下，仙草胶提取液的脱色率可达92.3%，多糖损失率为20.5%。

Abstract:

The paper aimed at studying on decoloration of hsian-tsao gum with activated carbon, and the optimum conditions were given by employing the factors of afecting decolorization. The best result was obtained when activated carbon dosage was 2.5%, decolorization temperature was 60 ℃ and decolorization time was 50 min, under which the decolorizing rate reached 92.3% and the loss of polysaccharide was 20.5%.
