Abstract: The aim of this study was to determine the shelf life post-harvest and kind of packaging of tomato cultivar Dominator, stored in environmental and refrigerated conditions. The product was packed in low-density polyethylene with a thickness of 35 μm and polystyrene trays expanded covered with flexible film of polyvinyl chloride with a thickness of 30 μm. As control treatment was used the product without packaging. The product was kept in environmental conditions at 24 ° C ± 5 ° C and relative humidity of 52% ± 5% and refrigerated conditions at 12°C ± 1 oC and relative humidity of 90% ± 5%. Initially, the tomatoes were analyzed for weight, diameter, length, pulp thickness and size of the vault. At the beginning and at four, seven and nine days of storage, pH, soluble solids, weight loss and sensory analysis was determined, considering the overall appearance, color, texture and flavour. The judges also opined that buy the product or not. The experimental design was completely randomized with three replications. Under the experimental conditions, the longer shelf life of fruit and packaging have been better to polystyrene trays covered with flexible PVC film under refrigeration, for better preserve the product, maintain its physical-chemical and reduce the weight loss cool. Fruits submitted to environmental conditions without package presented considerably shelf life. The major buyng possibility also occurred in fruit subjected to these treatments.
