Abstract

The objective of this study was to evaluate the effects of packing atmosphere alteration on the mangaba fruits quality (Hancornia speciosa Gomes), stored under refrigeration (11 ± 1°C), using polyvinyl chloride or low density polyethylene films, with or without potassium permanganate. Regardless the kind of film, the titratable acidity and soluble solids content increased, while the pH decreased, along the storage period. During that time, under modified atmosphere and refrigeration, fruits showed higher values for the soluble solids/titrable acidity ratio than other fruits. A significant loss of fresh matter occurred for the fruits packed with polyvinyl chloride, in relation to those packed with low density polyethylene. The fruits under atmosphere modified by polyvinyl chloride film, with or without potassium permanganate, and by low density polyethylene, with potassium permanganate, maintained good general features, until the eighth storage day. However, the fruits packed with low density polyethylene, without potassium permanganate, maintained their good features only until the fourth storage day. During ten storage days, none of the samples were visibly attacked by microorganisms.
