Abstract in Portuguese
Neste trabalho foram estudados os efeitos da radiação ionizante (gama) em mangas para exportação, simulando a etapa de acondicionamento da fruta durante o seu transporte, através da refrigeração em câmara fria. Em uma primeira etapa foram analisadas perda de peso, pH, acidez titulável, teor de sólidos solúveis, textura e decomposição. Posteriormente, realizaram-se análises sensoriais (alterações de cor, odor, sabor, textura). Os ensaios foram realizados em dois estádios de maturação das frutas, ou seja, 2 e 3, com o propósito de se estudar o melhor ponto de colheita para a melhor dosagem de irradiação. Os resultados revelam que o tratamento da manga Tommy Atkins na dose de 0,75 kGy foi significativo, juntamente com a fruta no estádio 2, para o retardo do amadurecimento e consequente ganho de tempo para a exportação.

Abstract in English
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.
