摘要
目的:考察WH706-CLL树脂对白及多糖提取液的脱色效果,建立最佳脱色工艺。方法:以提取液浓度、温度、pH值、流速为观察因素,以脱色率、多糖保留率作为考察指标。结果:在提取液质量浓度为1 mg·mL^(-1)、温度为50℃、pH值为6、流速为1 mL·min^(-1)的条件下,WH706-CLL树脂对白及多糖的脱色率为93.7%,多糖保留率为87.3%。结论:在设定工艺条件下WH706-CLL树脂对白及多糖的脱色效果良好,适用于白及多糖的脱色。
Objective： To investigate the decoloring effect of Bletilla striata polysaccharide extract by WH706-CLL resin, and establish the optimum process of decolorization. Methods： With extract concentration, temperature, pH value, flow rate as observation factors, the decolorization rate and polysaccharide retention rate were examined. Results： When the extract concentration was 1 mg · mL^- 1, the temperature was 50 ℃, the pH value was 6, and the flow rate was 1 mL · min ^- 1, the decoloring rate of WH706-CLL resin reached 93.7% and the polysaccharide retention rate was 87. 3%. Conclusion： Under the conditions of setting process, the WH706-CLL resin has good effect on the decolorization of B. striata polysaccharide, and is suitable for the decolorization of B. striata polysaccharide.
