摘要: 研究D-900阴离子交换树脂对巴戟天多糖的最佳脱色工艺。采用D-900阴离子交换树脂对巴戟天多糖进行静态和动态吸附试验,考察不同温度、树脂用量、流速和pH值等因素对吸附过程的影响,以脱色率和多糖保留率综合评价其脱色效果。最佳工艺参数为:采用动态吸附,柱溶液温度45℃、流速1.0BV/h、上样液pH6.0。使用D-900阴离子交换树脂对巴戟天多糖脱色可以获得较好的脱色率以及较高的多糖保留率。

Abstract: This study was undertaken to optimize the decolorization of polysaccharides from Morinda officinalis How. using D-900 anion exchange resin. Static and dynamic adsorption experiments were carried out to study the effects of temperature, resin dose, sample loading flow rate and pH on decolorization rate and polysaccharide retention rate. The optimal process parameters were dynamic adsorption at a sample loading flow rate of 1.0 BV/h, sample pH 6.0 and 45 ℃. In conclusion, higher decolorization rate and polysaccharide retention rate could be obtained by using D-900 anion exchange resin

Key words: Morinda officinalis How., polysaccharide, discoloration, anion exchange resin
