摘　　要：比较了6种树脂对向日葵盘果胶液的脱色效果。在静态吸附试验研究的基础上,筛选出效果较好的树脂进行动态试验研究。实验表明:D900型吸附树脂对向日葵盘果胶提取液具有较好的吸附脱色效果和较低的果胶损失率,该树脂对向日葵盘果胶脱色的适宜工艺参数为:室温(约25℃),流速3.6BV/h,上柱液pH为4左右。此工艺对果胶提取液中色素的吸附率可达84.3%。树脂吸附后可用70%乙醇进行洗涤再生。Decoloration effects of six ion exchange resin and macroporous adsorption resins for sunflower head pectin were investigated.On the base of static adsorption,the best resin D900 was selected to fulfill the dynamic adsorption experiments.The results showed that D900 had higher decoloration effect and lower pectin loss ratio when it was used to treat sunflower head pectin with the following technology parameters:room temperature(about 25℃),flow rate 3.6BV/h and pH value about 4.The decoloration ratio was almo...
