摘要
分别比较了DM301、DM130、NKA-9、NKA-Ⅱ、H103、ADS-17、D101、X-5 8种大孔吸附树脂对紫苏粕多糖提取液的脱蛋白和脱色效果的影响。在静态吸附试验的基础上,筛选较好的树脂进行动态吸附试验研究。结果显示,D101树脂对紫苏粕多糖提取液中的蛋白质和色素的吸附最多,表明其脱蛋白和脱色效果最好,且多糖的回收率最高,因此D101树脂最适于紫苏粕多糖的纯化。
Deproteinization and decoloration effects of macroporous adsorption resins DM301, DM130, NKA -9,NKA - Ⅱ , H103, ADS - 17, D101 and X - 5 for aqueous polysaccharide extract from perilla meal were compared. On the basis of static adsorption experiments, several resins were selected to fulfill the dynamic adsorption experiments. The results showed that D101 resin had the best capacity of adsorbing proteins and pigments, so it had the best deproteinization and decoloration effects. The recovery rate of polysaccharide was highest, and D101 resin was the most appropriate resin for purifing the polysaccharide of perilla meal.
