| Research Abstract |
In three sizes of agar gels (crush gel, 3.5 mm cube gel, 15mm cube gel), the destruction by chewing was affected in the size of gel. The influence of a thickening agent on the destructive process of a fish meat sausage changed with kinds of thickening agent. The relationship between the intra-oral shear rate and shear stress revealed that potato starch had a high shear rate but low shear stress, while guar gum and xanthan gum had a low shear rate and high shear stress. The maximum velocity in the pharyngeal region of vegetable juices with carrot puree decreased with increasing carrot puree concentrations significantly.
