Effect of Polyethylene Film Lining and Potassium Permanganate on Quality and Shelf-Life of Banana Fruits

Abstract

This study was conducted to investigate the effect of using polyethylene film lining, sealed or perforated, and potassium permanganate, in granular form or absorbed in filter paper, on quality and shelf-life of banana fruits. Polyethylene film liners, sealed or perforated, significantly delayed fruit ripening, maintained quality and extended shelf-life of bananas. The potassium permanganate (KMnO4) in both forms, granules or absorbed in filter paper, resulted in more delay of fruit ripening and extension of shelf-life of banana fruits. The sealed film liner and KMnO4 in the granular form were more effective in delaying fruit ripening and extending shelf-life of bananas. That was reflected in more delay in the climacteric peak of respiration, peel color development, TSS accumulation, fruit softening and reduced weight loss during storage of bananas.
