| Abstract(in English) | Eating experiences are composed of multisensory processes. The present study was conducted for investigating effects of mastication sound in food texture perception. Mastication sounds were recorded prior to the experiment for each subject. We selected rice cracker and rice dumpling as sound stimuli. These artificial mastication sounds were then presented to subjects during the experiment while they chewed a food out of seven kinds of stuff. The onset of the artificial sound was carefully timed with the onset of mastication. Subjects estimated the hardness and liquid proportion of each food, eaten with added mastication sounds, and reported the food texture using scales. The results show that rice cracker sound increases perceived hardness but decreases liquid proportion whereas rice dumpling sound decreases perceived hardness but increases liquid proportion. In addition, they estimated pleasantness. The results indicate that rice dumpling sound sometimes decreases pleasantness. |
