The guava fruit (Psidium guajava L.) Red cultivar is a product very perishable when it is storage in inappropriate conditions of temperature, relative humidity and packing. In this work the postharvest behavior and quality indexes of fruit were evaluated. Fruits were storage to different temperatures and packing conditions. The postharvest evaluation was made during 15 days and was utilized a completely random factorial design with three factors: time of storage with six levels (0, 3, 6, 9, 12 and 15 days), storage temperature with two levels: room temperature 37 ± 2 °C and 85 to 90% RH) and cold storage (9±2 °C and 85 to 90% RH); two type of package: tray of polystyrene covered with PVC film or aluminum foil. During storage was observed that time, temperature and packing type, have significant statistic effect (P<0.05) on equivalent diameter, sphericity, bulk density, total soluble solids, pH and titratable acidity of fruits. The fresh fruit packed in polystyrene tray covered with PVC film can be storage for a period of 10 days at room temperature and for a period of 15 days in cold storage.
