摘　　要：研究了制糖过程产生的焦糖色素非糖分在大孔树脂上的吸附性能。结果表明:大孔树脂SD300静态吸附焦糖色素溶液的优化工艺条件是色素溶液锤度1.2～1.8°Bx、操作温度80℃、树脂粒径30～60目、吸附时间1 h,此时脱色率为57.8%;大孔树脂SD300对焦糖色素溶液的吸附符合Freundlich等温吸附方程。The adsorptive performance of non-sugar caramel pigments generated from the sugar production on a macroporous resin SD300 was investigated. The results show that ①the optimized technology conditions of statically adsorbing caramel pigments on Resin SD300 was as follows： the brix of caramel pigment solution 1.2 -1.8°Bx, operating temperature 80℃, particle size of resin 30-60 mush and adsorbing time 1 hour, and the decoloration rate was 57.8% under the optimized conditions; and②the adsorption isotherms of caramel pigments on Resin SD300 belonged to Freundlich type.
