| Outline of Final Research Achievements |
This study is aimed to clarify the relationship between taste/odor and stress response of food chewing. The study divided into three purpose;
(1)Examine the taste/odor of chewing foods that cause stress, (2)To evaluate regarding higher brain functions and changes in the deliciousness of food, (3)The influence of the autonomic nervous regulation by differences in preferences for chewing food．
As a result, subjects could discriminate between the types of gum without prior information. Saliva cortisol concentrations were highest and lowest for the subjects who chewed the most flavourful gum and the least flavourful gum, respectively. In additon, no significant correlation was found between performances of the mental arithmetic test and subjective sensory evaluation, except for a weak negative correlation with taste. More examination will be necessary in future.
