The flavor of peel oil from citrus unshu irradiated with 150 krad cathode ray were investigated by gas chromatography. The sample irradiated and stored for 30 days showed browning and unfavorable odor although the degree of the browning was not same as the report of OJIMA et al. The yield of essential oil showed only a slight difference in all samples. Some changes were found in the carbohydrate components immediately after irradiation, whereas some changes were detected in hydrocarbon components, especially d-linonen and pinene after storage of irradiated samples. Unfavorable oder might be caused by the changes of quantitative ratio of the components.
