Abstract: Mangoes ripen quickly and lose quality when stored at ambient temperature. This study assessed the effects of pre-harvest packaging, 2% calcium chloride (CaCl₂), 1.5% potassium sulphate (K₂SO₄), and 2% CaCl₂+1.5% K₂SO₄ + packaging on the post-harvest quality and shelf life of mango fruits at ambient temperature for 16 days. Fruits were sprayed three times at 30, 20, and 10 days and packaged in brown paper bags 20 days prior to harvesting. The results revealed that 2% CaCl₂+1.5% K₂SO₄ + packaging significantly improved fruit quality than control in terms of peel colour, firmness, ascorbic acid, total sugar, total phenol, antioxidant, peroxidase and catalase activity; reducing decay percentage, total soluble solids, polyphenol peroxidase; delaying weight loss, respiration rate and ethylene production. Consequently, 2% CaCl₂-treated fruits had higher titratable acidity and β-carotene compare than control at 16th days of storage. These physiochemical data suggest that 2% CaCl₂+1.5% K₂SO₄ + packaging may improve Haribhanga mango storage.
