| Outline of Final Research Achievements |
To estimate food texture quantitatively, it needs examination of mechanical properties corresponding to the sensory test. This study estimated microscopic level of material properties of snack foods. The results show 5 to 700 times larger than those of macroscopic level. Next we researched a relation between structural characteristics of snack foods and onomatopoeia in masticating these foods, and proposed a mathematical model to explain the relation. We also analyzed jaw movement in mastication of foods, and demonstrated that the movement changed by the kinds of foods.
