| 摘 要： | 研究色素在低甲氧基大豆皮果胶和壳聚糖复合凝胶中的扩散行为。结果表明，一级动力学方程较好地描述了色素在复合凝胶溶胀状态下的扩散过程。利用均匀设计方法获得表观速率常数及扩散系数的多元二次回归方程，合理地表征了各因素对动力学参数的影响情况，扩散动力学参数反映了凝胶网络结构的特征。

| Abstract: | In this study,the experimental method uniform design was adopted to investigate the diffusion behavior of food brilliant blue 2 in a complex gel formed from low methoxyl pectin soy hull and chitosan.The results showed that the first-order kinetic equation could describe the diffusion of the pigment in the complex gel system at swelling state.Two multiple quadratic regression equations were obtained as a reasonable characterization of apparent rate constant and diffusion coefficient as a function of various ... |
