Subjective palatability is related to human’s mental condition. According to Ministry of Health, Labour and Welfare JAPAN, unusual feeling palatability is one of depression signs. Additionally psychogenic taste disorder is occurred by stress. Subjective palatability sensing is expected to make human realize own mental health condition at objectively. However, it is difficult for us to measure subjective palatability because it has differences among individuals and many factors. We try to elucidate the relation between subjective palatability and facial biological information in order to consider subjective palatability sensing method. We found 2 relation from our experiment by using taste stimulations for 4 subjects. 1st is between vertical EOG variance and intensity of subjective palatability. 2nd is iEMG(integrated electromyogram) and tasteless or tasty. We implement subjective palatability calculation program from them. The result of it using measurement data in this study experiment shows the possibility of subjective palatability sensing.
