Baladi Oranges are widely consumed, whether fresh or in juice, for healthy nutrition, but the long storage period reduces the quality characteristics of the fruits. To save antioxidant effects in orange under storage. Chitosan and propalis in different concentrations on pre-harvest and post-harvest were studied. On the first subject of study, two weeks before harvest on the orchard in the Aga Region, the fruits were sprayed with chitosan 1%, chitosan 2%, propalis 1%, propalis 2%, acetic acid 5% (to review the outcomes were for chitosan or acetic acid as a solvent), ethanol 6% (to review the vestige were form propalis or for ethanol as a solvent). The second subject was dipping fruit after harvest with looks like solutions to compare the best spraying fruits before harvest or treatment it by dipping after harvest. In the two trials, fruits were harvested on the same day and in the same orchard at the physiologically mature stage with uniform appearance and without disease. The rustles declared the effects were chitosan and propolis, not acetic acid or ethanol. Rustles revealed that coating fruits for storage are better than treating them before harvest. The optimum treatment for good quality was propalis at 2%.
