摘　　要：研究了5种树脂对菊芋(Jerusalem artichoke)菊糖溶液中色素脱除效果,通过单因素试验和正交试验对其脱色条件进行优化。结果表明,采用树脂D3520,在pH 6、40℃下,菊芋菊糖溶液的脱色率可达到80.51%,菊糖保留率为70.49%,树脂对菊芋菊糖中色素的吸附为单分子吸附,符合Langmuir吸附等温式,其吸附动力学符合扩散方程。The decoloration effects of five kinds of resin on inulin(Jerusalem artichoke) oligosaccharides were investigated;and the decoloration technology was optimized by single factor test and orthogonal experiment.The results showed that adsorption effect of D3520 resin was the best.The optimum decoloration parameters were temperature 40 ℃ and pH 6.The decoloration rate was 80.51%,while the polysaccharides retention rate was 70.49%.The adsorption of pigment in inulin oligosaccharides was accord with single molecule adsorption and Langmuir isotherms equation,the adsorption dynamics was accord with diffusion equation.
