三偏磷酸钠交联马铃薯淀粉颗粒膨胀历程及溶胀机理研究

Study on Swelling Process and Mechanism of Cross - linkedPotato Starches Granules

本文利用淀粉与三偏磷酸钠的交联反应,通过控制交联反应程度,成功地控制了交联淀粉颗粒地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交联淀粉颗粒的结构特征和变化趋势,揭示了交联淀粉颗粒由高交联非糊化到低交联溶胀糊化具体地膨胀历程及溶胀机理,即交联马铃薯淀粉是以颗粒尾端为主的不均衡膨胀。

With the reaction of starches and sodium trimetaphosphate, swelling of cross - linking starch granules was controlled successfully through different degree of substitution. The structure characteristic and change tendency of starch granules at different swelling stages were investigated potato starches swelled firstly and mostly at the tail.
