title: Development and validation of a mastication simulator.
abstract: More and more research are being done on food bolus formation during mastication. However, the process of bolus formation in the mouth is difficult to observe. A mastication simulator, the Artificial Masticatory Advanced Machine (AM2) was developed to overcome this difficulty and is described here. Different variables can be set such as the number of masticatory cycles, the amplitude of the mechanical movements simulating the vertical and lateral movements of the human lower jaw, the masticatory force, the temperature of the mastication chamber and the injection and the composition of saliva. The median sizes of the particles collected from the food boluses made by the AM2 were compared with those of human boluses obtained with peanuts and carrots as test foods. Our results showed that AM2 mimicked human masticatory behavior, producing a food bolus with similar granulometric characteristics.
