Abstract : The present investigation was conducted during 2006-07, 2007-08 and 2008-09 at Post Harvest Technology Laboratory, Navsari Agricultural University, Navsari. An experiment was laid put in Completely Randomised Design with Factorial concept with three factors at different levels viz., hot water (2-levels i.e. H1 - Hot water treatment at 52°C for 10 minutes and H2 - Without hot water treatment), pre-cooling (4-levels i.e. C1 - Hydro-cooling at 8°C for 10 minutes, C2 - Hydro-cooling at 12°C for 10 minutes, C3 - Fruits pre-cooled at 8°C for 30 minutes and C4 - Fruits pre-cooled at 12°C for 30 minutes) and packaging treatments (4-levels i.e. M1 - LDPE packaging, M2 - HDPE packaging, M3 - News paper packaging and M4 - Tissue paper packaging) were studied. Results indicated that the hot water treatment (H1) at 52°C for 10 minutes, hydro-cooling at 8°C for 10 minutes (C1) and HDPE packaging (M2) of mango fruit had minimized the physiological loss in weight (%), ripening (%) and spoilage (%) during storage. Consequently, these treatments also significantly increased the days required for ripening and ultimately increased the shelf-life of mango fruits during storage at ambient temperature.
