| Research Abstract |
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.
