| Outline of Final Research Achievements |
In the sol-gel transition of food macromolecules, the intermolecular hydrogen-bonding among macromolecules are broken down to bring about the hydration of macromolecules so that the water activity, as an index of the bulk state of water, is expected to affect the transition process strongly. From this standpoint of view, the sol-gel transition of food macromolecules, such as gelatin, was analyzed to show an important role of water activity in such phenomena. This result will provide an entirely new approach in the study of physical properties of food macromolecules.
