Research Abstract

An ultrasonic pulse Doppler method, rheological measurements, and sensory evaluation were used to determine the effects of the amounts of gel and mastication on the velocity of agar gel, gelatin gel and agar gel dispersed in paste passing through the pharynx as well as the physical characteristics following mastication. Possible reasons for the increase in the maximum velocity of bolus passing through the pharynx include the fact that agar gel leaves behind a large bolus after mastication, and that gelatin gel changes in form from a gel to a sol. In agar gels dispersed in xanthan gum paste, guar gum paste, starch paste and water, the maximum velocity of xanthan gum paste was not influenced by the mixing ratio and mastication. From above results, the maximum flow rate of bolus passing through the pharynx is discovered to decrease, as the bolus became soft and turns into a lump.
