Summary
A large number of studies have reported the findings for masticatory efficiency tests; however, some objective masticatory efficiency tests have a drawback, in that subjects are required to spit out the test material. The present study examined the possibility of a masticatory efficiency test that evaluates the intensity of odors released when chewing an odor compound-containing material. A total of 20 volunteers were used in this study. The odor intensity in the breath after chewing a gum was measured by portable odor sensor device. The odor intensity after chewing the gum was measured over four chewing durations, and at four intervals between spitting out and measurement of the odor intensity. The volume of stimulated saliva was measured by calculating the difference in the weight of the gauze before and after chewing to examine the effect of saliva flow. With an increase in chewing duration, odor intensity reduced. The odor intensity was the highest immediately after chewing. There was a positive correlation between odor intensity and gummy jelly-related masticatory efficiency test value (G-METV), which was significant for 10-sec chewing. The regression equation was calculated from three objective variables of odor intensity, and G-METV as dependent variable. The Pearson's correlation coefficient between G-METV and the odor intensity-related masticatory efficiency value (O-METV) was 0.68. The coefficient of variation of O-METV was significantly lower than that of G-METV. These results suggest that the masticatory performance can be estimated by measuring the odor intensity immediately after chewing food containing odor compounds for 10 sec.
