Outline of Final Research Achievements

Taste modification by mixing two tastes that indicate perceptive time variance was investigated. The experimental equipment for offering taste solutions to human have been manufactured but not enough validated, so animal behavioral analysis have been performed. In the case of combination among sweeteners, the greater effects of sweet enhancement were observed in the larger differences of perceptive time. However, in the case of combination sweet and salty, the greater effects of sweet enhancement were observed in the mixture with ionized sweeteners, that were perceived faster.
