Banana fruit were exposed to hexanal vapour at 600, 900 and 1200 ppm for two and four h at 27±2°C. Fruits were then stored at 27±2 ° C with 65-75% relative humidity and latter assessed for quality. The rate of respiration, increase in TSS and loss of firmness were affected negatively by hexanal vapour treatment. Changes in the peel colour were also slowed compared to untreated fruits. | Effect of Hexanal Vapour on postharvest quality and shelf life of Banana var. grand naine
