Abstract

Purpose: Ineffective storage technology is the major concern for the high level of postharvest loss in Bangladesh. So, aiming to pick out the promising storage strategy of mango, this study was conducted. Research method: The mangoes cv. Amrapali were kept under two storage conditions viz., ambient and refrigerated (13 ± 2 °C and 15-20% RH) storage having five postharvest treatments including untreated control, perforated polyethylene bag, unperforated polyethylene bag, chitosan coating and edible oil (soybean) coating. Findings: The effect of storage conditions and postharvest treatments were found highly significant on the chemical parameters. Unperforated polyethylene bag and oil coating showed the highest titratable acidity (0.51 and 0.50%), the highest vitamin C (22.43 and 22.63 mg/100 g), and the lowest TSS (8.90 and 10.00%) under refrigerated condition and control showed the lowest titratable acidity (0.10%), the lowest vitamin C (12.50 mg/100 g), and the highest TSS (27.03%) under ambient condition at 9 days after storage. Unperforated polyethylene bag and oil coating under refrigerated conditions kept mangoes edible up to 9 days after storage. But after certain days of storage, unperforated polyethylene bag and oil coating developed off-flavor making mangoes inedible. Research limitations: More research should be conducted using other mango cultivars. Originality/Value: The perforated polyethylene bag under refrigerated condition showed a slower change of chemical parameters, simultaneously resulting in the longest shelf life (27 days) without producing any unwanted flavor and taste indicating efficient postharvest storage.
