To insert the fresh cut fruit to markets is necessary to ensure that visual quality is not altered by the process of peeled and sliced; and also must ensure physical chemistry product quality. It was evaluated the physicochemical and physic properties of the pulp of green plantain (PPV), after vacuum impregnation (IV) with two solutions containing antioxidants (1: Sulfites 500 mg/kg PPV fresh, 2: mixture of 90 mg and 100 mg ascorbic acid citric acid / kg PPV fresh) plus preservatives, NaCl and EDTA, with and without vacuum packed (CV and SV), and stored at 4°C for 0, 3, 6, 9, 12 and 15 days; in addition, it was compared with PPV without impregnating the same storage conditions. There was a tendency to decrease the pH and content of sulphites, and increase the °Brix, acidity and enzyme activity, while the aw and humidity showed no significant changes. Treatments controlled enzymatic browning for 15 days in the PPV were all those conditions packaged CV, besides to treatment with sulfites SV. The samples impregnated with the sulfite solution and packed CV and SV, had the higher strength, making these the most appropriate treatments for minimally processed PPV use as feedstock in the snack industry.
