Outline of Final Research Achievements

Developed device system that makes it possible to distinguish foods by combining sensor which is substitute of human taste or olfaction. Based on physical property values at the time of sea salt production, concentration of Na, K, precipitation of Ca gypsum, residual concentration of Mg affected salty taste. As a result of measuring physical property values of seasonings that seven species, it is suggested that component ratio of mixed soup can be classified from electric conductivity and pH. In addition it is suggested that detection of umami ingredients and concentration prediction was suggested possibility. When brewing of fruit vinegar from reddish purple fruits and verification of attenuation rate of functional dyes in manufacturing process showed that control of increase rate of alcohol concentration rise and temperature in order to maintaining functional dyes at each fermentation was found to be important.
