Abstract (in Japanese) (See Japanese page) 
(in English) Up to now, investigations on the inhibition of bitter taste have been made on quinine which has a positive charge. In this study, effect of food constituents on picric acid which has a negative charge was examined with taste sensor. As a result, response of the sensor to picric acid was diminished by sodium salts of organic acid and fatty acid. The decrease of the potential change of response implies depression in the intensity of bitterness. As the hydrophobicity of fatty acids increased, the suppression of bitterness was also increased.
