The experiment was conducted in order to determine the appropriate irradiation dose forextending the storage life of fresh banana. The experimentalbananas (cavendishvariety)were obtained from the farmersin Ciseeng, Bogor. The middle bunch of banana was choosen for irradiationwith the dose of 0, 0.25, and 0.5 kGy andstored under temperature 20°C and relative humidity 85 - 90%.Toevaluatethe qualityof banana,severalparameterswere examined namely, total sugar content, ascorbic acid content, texture and visual test. The results of this experimentrevealed that total sugar content obtained during storage can be used as an index to evaluate the ripeness of banana.Based on the physico-chemicalanalyses and visual test, it can be concluded that the dose of 0.25 kGy is quite effectiveto extend the storage life of banana from 20 days up to 35 days.
