| Outline of Final Research Achievements |
Somatic and autonomic responses to detection of three fruit flavors (apple, orange, and strawberry) in jelly samples were examined in healthy young participants by using blink and heartbeat intervals as physiological indicators. Both blink and heartbeat intervals were decreased significantly compared to those before the detection. The blink and heartbeat intervals before the detection were negatively and positively, respectively, correlated with those during the detection. Blink and heartbeat intervals are generally decreased with strengthening mental tension, so the significant decreases in these intervals suggest that mental tension was weakened during the detection. It is considered from the present results that the detection of food flavors can strengthen mental tension which is reflected by somatic and autonomic responses.

| Academic Significance and Societal Importance of the Research Achievements |
日常生活で口にする食品のほとんどには、何らかの風味があって食生活を豊かにしてくれる。そのような食品風味が心身に及ぼす影響を瞬きと心拍の変化で調べた。実験結果から、いずれも風味の検出中にはその直前に比べて間隔が短縮する、すなわち頻度が増えるとわかった。風味検出中という短時間の変化を明らかにできたのは学術的に意義が大きい。また、これらの身体的変化からは、風味検出時に心的緊張が強くなる可能性が考えられる。心的緊張の増大が示す意味をよく吟味すれば、本研究で得られた知見は食品開発などに応用が可能と期待できる。
