Postharvest Storage and Shelf Life of Mango: Effects of Postharvest Storage Treatments on Physicochemical Properties and Shelf Life of Mango Nurul Absar

An investigation was conducted for obtaining information on the reduction of postharvest losses, pattern of physical, biochemical and mineral content changes, storability as well as shelf life of postharvest mango. The trials included four different experiments involving two factors where variety was a factor comprising of Langra and Khirshapat. These varieties were treated with different postharvest treatments viz., control, paraffin coating, perforated polyethylene cover, unperforated polyethylene cover, hot water (55±1)0C, low temperature in refrigerator (4±1)0C; different doses of Maleic hydrazide, GA3 and Bavistin DF solution. These experiments were laid out in Randomized Complete Block Design with three replicates. Different postharvest treatments subjected to the investigation demonstrated significant variation in most of the physicochemical properties and shelf life of mango. Low temperature in refrigerator was the best inhibitor of ethylene synthesis that delayed ripening and prolonged shelf life. The second suitable method was found to be 400 ppm of GA3 which is cost effective and might easily be adopted by common farmers for mango preservation.
