Postharvest orange fruit coating is an effective method to replace natural waxes which lost during washing and handling. The coatings can reduce water loss and impart gloss to the fruit. In this study, the oranges were stored at room temperature (30 ± 2oC) with five coating materials: polyethylene (PE), polypropylene (PP) bags, polyvinyl chloride (PVC) film, Citra Shine preservatives and 1% chitosan and the control were used. Some typical nutritional values and weight loss were determined during storage time. Research results show that PVC coated ‘Sanh’ oranges could be prolonged their shelf life up to 25 days with low damage ratios (7.10%, lower than other bags) which were acceptable in appearance with green peel color. Ascorbic acid content still maintained at a high level (12.32 mg/100 g), and weight loss relatively low (13.91%). Moreover, pH (3.77) and TSS (9.70) values did not significantly change during storage time.
