【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50min,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%。更多还原

【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%.更多还原
