| Outline of Final Research Achievements |
We constructed a system that mimics physical phenomena occurring in the oral cavity to show the expression mechanism of the texture when human eat foods. First, a tongue and tooth model were prepared by carving a hierarchical fractal structure on the surface of an agar gel and apatite/starch composite material. In addition, we evaluated the compression and friction properties of soft gel and emulsion on fractal agar gel and showed that the rough structure on the fractal agar gel affects the behavior of food. We found correlation between the friction change and sensory scores when subjects drunk the thickener solution. These findings will be useful for understanding the origin of food texture.
