In order to characterize odor-descriptive terms, a response pattern matrix was made with 44 terms and 53 kinds of foods by evaluating the odors of foods. The matrix was analyzed by quantification theory 3 and cluster analysis was done on the scores from the first to fifth axis obtained by quantification 3. (1) The terms were separated into 12 groups on the basis of their odor images by analyzing the sum of the three data sets obtained by the research workers of Ajinomoto Co., Inc., the food flavorists of Ogawa Co., Ltd. and the graduate students of a laboratory of food analysis. (2) In the result of untrained panelipanelists, the difference between the odor image of"value"and"activity"was indistinguishable. (3) With comparing the results of trained and untrained panelists, 35 of the terms were classified into the same odor groups.
