| Outline of Final Research Achievements |
This study investigates experimentally and numerically how the food bolus formation is affected by food rheology, cookery and so on.
1) We clarify the correlation between the mean size of gel pieces and the number of chewing cycles examined by the mastication experiments. 2) In order to measure the cohesiveness of food bolus, we propose a random packing model for the food bolus formation. The model produces a fragment with randomly choosing radius according to a particle size distribution. To simulate this model, the relation between the porosity and cohesiveness of food bolus was obtained.
