| Outline of Final Research Achievements |
Food aroma is one of the most important factors which decide food palatability. Behaviors of volatile compounds, which make sensations for olfaction, were investigated with focus on released amount from model food, bolus conditions, and influences of seasoning substances. Most volatile compounds are oil-soluble, and LogP, the index for liposolubility, of 5056 compounds were collected from published reports date and from calculation with software, classified, and some data from old publishing were found not to be reliable. The amount of volatile compounds was influenced by co-exist substances, like seasonings (sugar and salt) and interactions between volatile compounds and co-exist substances were verified. Mastication properties were also influenced by bolus physical properties, and changes of perceived flavor attributes during mastication were observed.
