Resumo
Brazil is a great producer of tropical fruits including mangoes. Among several purposes gamma radiation can be applied as phytosanitary treatment. This is well studied in scientific papers and more recently demonstrated through commercial advances like bilateral protocols established between India and USA. The whole experiment evolved two parts where each of them used fruits from different maturity stages (stages 2 and 3). This experiment was carried out with around 300 fruits in each part of the study. The main objective was to get the experience close to commercial conditions. The irradiation was realized in Multipurpose Cobalt-60 source belonging to IPEN-CNEN/SP (developed in house by own technology). The absorbed doses were 0.2, 0.5 and 0.75 kGy. After irradiation all fruits were kept at 12 °C in acclimatized chamber during 14 days. After this period the fruits were brought to environmental conditions (25 °C) for around 14 more days of duration. These conditions were established to simulate the exportation conditions from Brazil to distant countries. Physical-chemical analysis (pH, titrable acidity, total soluble solids (°Brix) and texture) as well as visual observation (mass loss, rotting, internal and skin color) were evaluated. The results from this experiment could demonstrate that the characteristics of the mangoes are more dependent on time and temperature storage rather than irradiation.
