| Outline of Final Research Achievements |
In the present study, we attempt to assess the oral residue and the pharyngeal residue using odor sensor. At first, the aroma of expired air from oral cavity was measured during holding flavor essence. In the result, the aroma of expired air was increased with the amount of holding flavor essence. Second, the retro-nasal aroma from naris was measured for estimating the pharyngeal residue. 0.2, 0.4, 0.6 ml flavor essence was injected to the pharynx of the subjects, and the subjects were instructed to hold it 120 seconds without swallowing before swallow. In the result, the intensity of retro-nasal aroma had a significant liner correlation with the amount of the flavor essence.
