    Distributors of citrus fruits in Puerto Rico produce peeled oranges as their main product, however this product is highly perishable. The main objective of this research was to compare different edible film treatments for extending the shelf life of fresh peeled oranges stored at 4 ± 0.5 º C. Four edible films treatments were evaluated as follows: NatureSeal® (NS), NatureSeal® with 2% of potassium sorbate (NS+SP), hydroxypropyl methylcellusoe with 2.5% of glycerol (HPMC), hydroxypropyl methylcellusoe with 2.5% of glycerol and 2% of potassium sorbate (HPMC+SP) and a control treatment (fruit without edible film). In petri plate aerobic microorganism, fungus and yeast were counted. Weight lost, external appearance, texture, color, pH, water activity (aw), ºBrix, vitamin C and acid titration were measured in the treatments. The analyses were performed at 0, 3, 7, 14, 21, 28 days after application of the edible film treatments. Overall, the SP edible films had the lowest microbial counts. There were no significant differences among edible films regarding weight lost, texture, pH, aw, ºBrix, vitamin C and acid titration. The HPCM edible films had the best external appearance. Overall, this study found the edible film HPCM+SP produced the best results.
