| Research Abstract |
Polysaccharide solutions with the same viscosity at shear rates 10～50s^<-1> and with different shear thinning behaviours have been prepared and X-ray videofluorography was carried out. Numerical simulations on the risk of aspiration as a function of bolus quantity and bolus viscosity were performed and supported the videofluorographic observation. Solutions for monitoring aspiration with different symptoms were developed, commercially available thickened liquid foods were analyzed, and the relation between newly developed liquid foods and commercial foods was examined, and thus the basis of a systematic method of monitoring aspiration was established.
