In conclusion, the results obtained in this study provide evidence of the ability of oxalic acid to maintain peel appearance and to extend the green shelf life of banana fruit during storage at room temperature and exhibited the potential for commercial application to store the bananas at ambient temperature. Together with other studies (Whangchai et al., 2006 and Zheng and Tian, 2006), it is suggested that the oxalic acid treatment is a safe and promising postharvest handling technology for maintaining quality and prolonging storage life of harvested banana fruit. Further work is needed to understand better the mechanism by which oxalic acid delays fruit ripening at the molecular level.
