摘要
目的:优选苦豆子多糖活性炭脱色工艺。方法:以活性炭添加量(W/V)、脱色时间、脱色温度为考察因素,通过单因素试验(以脱色率、多糖损失率为指标)和响应面法(以脱色率为指标)优化苦豆子多糖活性炭脱色工艺。结果:最佳脱色工艺为活性炭添加量(W/V)占0.99%,时间59.6min,温度40.3℃,其脱色率可达到66.4%。结论:该脱色工艺适合工业化生产。
OBJECTIVE： To optimize the decolorization technology of Sophora alopecuroides polysaccharide with activated carbon. METHODS：The decolorization technology of S. alopecuroides was optimized by the single-factor experiment （decolorization ratio and loss rate of polysaccharide as index） and response surface method （decolorization ratio as index）,with adding amount of activated carbon addition （W/V）, decolorization time and temperature as factors.RESULTS： The optimal decolorization technology was as follows： activated carbon addition （W/V） accounted for 0.99%, decolorization time 59.6 min, decolorization temperature 40.3 ℃ and the decolrization rate 64.3 %. CONCLUSION： The decoloration technology is applicable for industrialized production.
