Abstract

It had been studied the effect of the ionizing radiation (gamma) in mangoes for exportation, simulating the stage of preservation of the fruit during its transport, through the refrigeration in cold chamber. In a first stage they had been analyzed through loss of weight, pH, treatable acidity, soluble solid, texture and decomposition. Later, sensorial analyses had been become fulfilled (alterations of color, odor, flavor, texture). The assays had been carried through in two stadiums of maturation of the fruits, that is, 2 and 3, with the intention of studying optimum point of harvest for the best dosage of irradiation. The results disclose together that the treatment of the mangoes Tommy Atkins in the dose of 0,75 kGy was significant, with the fruit in stadium 2, for the retardation of the matureness and consequent profit of time for the exportation.
