Abstract : Mangoes (Mangifera indica cv. Espada), in natura, at development physiological mature stage, were individually packed in terephthalate polyethylene trays (dimensions: 11.0×11.0×2.5 cm) wrapped with nonperforated polyvinyl chloride (PVC) film, and with perforated plastic put upon in terephthalate polyethylene trays; and stored at 10, 12, 14°C and environment (76-85% UR) during 35 days. The analyses were made at every 7 days, with non-sealed fruits serving as the control. During the experiment, the peel and fresh colours of the mangoes were studied using nonstructured hedonic scale to observe the change in the coloration from green to yellow through the storage time, and to identify the procedure that best keep the original aspects of the product and the procedure to increased its shelf life. The influence of factors such as temperature, packaging and storage time; and their interaction with the results were submitted to variance analyses and the average values were compared by Tukey's test. In conclusion, the results proved that the use of nonperforated PVC film provided a modified atmosphere associated with low temperature, and increased the shelf life of the fruits keeping the peel and flesh colours.
