Ultra-violet C (200-280 nm) was able to sanitize and retard microbial growth on the surface of food without causing undesirable quality changes. Therefore, this study was conducted to determine the effect of UV-C radiation on Musa AAA ‘Berangan’ fruit quality after storage. Mature green banana was exposed to 0, 0.01, 0.02, 0.03, 0.04 and 0.05 kJ m-2 UV-C. Then, the fruit was packed into cartons and stored at 13°C/75% relative humidity for 0, 1, 2 and 3 weeks. At the end of each storage week, a cluster of fruit from each UV-C dose was removed from the box and initiated to ripen using 1 ml L-1 ethylene. After 24 h, the fruits were allowed to ripen at 27°C/85% relative humidity and analysis was carried out at day 0 (before ripening initiation), 1, 3 and 5 (after ripening initiation) for peel colour (L*, C* and h°), pulp firmness and soluble solids concentration (SSC). The three factors of this experiment were arranged in a randomized design with four replications. Data was analyzed using ANOVA and means were separated using Duncan’s multiple range test. The L*, C* and h° of banana peel, firmness and SSC were affected significantly by interactions between UV-C dose × storage week, UV-C dose × ripening day, storage week × ripening day, and UV-C dose × storage week × ripening day. Regardless of irradiation dose, h° values and pulp firmness of ‘Berangan’ banana decreased while L* values and SSC increased with storage. Similarly, h° values and pulp firmness of all treatments decreased while L* values and SSC increased as ripening progressed. This result indicated that UV-C irradiated ‘Berangan’ banana fruit was able to undergo normal ripening after storage.
