| Research Abstract |
This study investigates experimentally and numerically how mastication and swallowing processes are affected by food rheology, cookery and so on.
First, fragment-size distributions have been studied experimentally in masticated fish sausage. The result indicates that the fragmentation pattern by human mastication for fish sausage is different from the fragmentation pattern for wet crisp food, and we propose a mathematical model for the ingestion process by human.
Second, to investigate the mastication and swallowing efforts for finely cut foods, food bolus generated from masticated foods were analyzed by fragment-size, rheological and physiological tests.
The results of this study were published in academic journals
