| 摘 要： | 对菊芋菊糖提取液活性炭脱色工艺条件进行了研究，比较了几种不同厂家生产的不同规格的活性炭对菊芋菊糖提取液的脱色效果. 结果表明，仅粉末状活性炭TS4具有脱色作用，且脱色效果显著. 通过单因素实验和正交实验确定的菊芋菊糖提取液活性炭TS4脱色的最佳工艺条件为活性炭用量5 g/L，脱色温度80℃，pH值6.0，时间30 min. 在此条件下，脱色率达82.6%，菊糖回收率可达93.4%.

| Abstract: | In order to explore the decolorization technology of inulin from Jerusalem artichoke tubers, the effects of active carbon at several sizes from different manufacturers on decolorization of the inulin were investigated. The results showed that activated carbon TS4 was the best adsorbent for adsorbing the dye in the inulin extract. The optimum decolorization conditions were determined through single factor and orthogonal experiments as follows: activated carbon dosage 5 g/L, decolorization temperature 80℃, pH value 5.0 and decolorization time 30 min. Under these conditions, the decolorization rate and recovery rate of inulin reached 82.6% and 93.4%, respectively. |
