三氯氧磷交联木薯淀粉颗粒膨胀历程及溶胀机理研究

利用木薯淀粉与三氯氧磷的交联反应，通过控制交联反应程度，成功地控制了交联淀粉颗粒的膨胀并使其停留在不同的溶胀阶段，详细地研究了处在不同溶胀阶段的三氯氧磷交联木薯淀粉颗粒的结构特征和变化趋势，揭示了三氯氧磷交联木薯淀粉颗粒的具体的膨胀历程及溶胀机理，即木薯淀粉是“花蕾绽放式”膨胀历程。

Study on Swelling Process and Mechanism of the Cross - linked Tapioca Starches Granules

With the reaction of tapioca starches and phosphors oxychloride,the swelling of cross-linking starch granules was controlled successfully through different degree of substitution.In the different swelling processes,structure characteristics and tendency changes of starch granules were discussed. Furthermore the swelling process and mechanism of starches granules also showed that the cross-linked tapioca starches swelled like a bud blooming into a flower.
