中文摘要
我们用H/D对比非弹性中子散射实验研究了食品蛋白质的水合水动力学。我们发现,水的活度与食物中的水合作用、水动力和水化结构有关。蛋白质的玻璃化转变与食物的质地有关,与水合水网络相关。这些结果表明,食品的保鲜和质构与食品中的水化结构和水化水动力学密切相关,非弹性中子散射是食品分析、水离子和玻璃化转变的有效实验方法。
英文摘要
We examined the hydration water dynamics of food protein by H/D contrast inelastic neutron scattering experiment. We found that the water activity is correlated with the hydration water dynamics and hydration structure in food. And the glass transition of protein, which is relevant to the texture of food, is correlated with the hydration water network. These results indicate that the food preservation and texture is highly relevant to hydration structure and hydration water dynamics in food, and inelastic neutron scattering is effective experimental method in food analysis, hydraion and glass transition.
