Abstract


The objective of this experiment was to evaluate the post harvest conservation of mangos ‘Tommy Atkins’, during a storage, using different types of packings. The modified atmosphere corresponded to the following treatments: fruits conditioned individually in plastic trays, covered with plastic film of polivinila chloride (PVC) of 14 µm, without and with sachet of potassium permanganate (10 g); fruits conditioned individually in polyethylene bag of low density 25 µm of simple wall addictived or not with potassium permanganate; conditioned fruits, in groups of 5, in carton boxes with cover, covered internally or no with low density polyethylene film addictived with potassium permanganate. The fruits were stored under storage room at 24,4 ºC, 70 % RH. The evaluated variables were: loss of fresh mass, appearance, firmness of the pulp, soluble solids, titratable acidity and ascorbic acid. It were verified that the best treatments of modified atmosphere were individual packaging of the mango fruits in plastic trays, covered with plastic film of polivinila chloride (PVC) of 14 µm, without and with sachet of potassium permanganate. The potassium permanganate, in the form used in this study (sachet and impregnated in plastic film), did not interfere in the results obtained for the conservation of the fruits.
