Perceptual Changes in Taste Perception during Category-Mismatched Taste and Olfactory Presentation Using a Breath-Synchronized Olfactory Display

Abstract

Simultaneous presentation of category-mismatched visual and olfactory information with food changes the perceived flavor, but the effect of category-mismatched taste-olfactory information on the perceived flavor remains unclear. In this study, fish odor was presented during the ingestion of beef jerky using the Breath-Synchronized Olfactory Display, and the effects of category-mismatched taste and olfactory stimuli on perceived flavor were evaluated. As a result, the sensation of beef jerky was reduced with the breath-linking olfactory fish odor stimuli, and the sensation of dried squid was strongly perceived. The results suggest that the integrating category-mismatched taste and olfactory information changes the categorical perception of flavor.
