In order to studythe application of event-related potential (ERP) for performing evaluation of food, the ERP was measured when subjectively judging the appearance of foods by three-grade scale with the opinion “Like” and “Favorite”. Sushi was selected as typical foods. And six pictures of sushi were chosen in such a way that it did not consist of disliked sushi of the subjects. As a result, the P300 component of the ERP was detected, and the P300 area (surrounded by ERP waveform and x axis from the latency 250 to 500 ms) became larger when the subjects judged as “Favorite”.
