EFFECT OF MODIFIED ATMOSPHERE PACKAGING ON SHELF LIFE AND QUALITY OF 'BHAGWA' POMEGRANATE IN COLD STORAGE
An experiment to investigate modified atmosphere packaging to improve shelf life and maintain quality of Bhagwa pomegranate fruit was conducted using polypropylene (PP) bags of 12.5 micron (50 gauge), 25 micron (100 gauge) and 37.5 micron (150 gauge) and StePac, Xtend® modified atmosphere/modified humidity bags and control (without packaging in CFB boxes). The packed fruits were stored at 4±1°C. Pomegranate fruits were evaluated for changes in physiological loss in weight, colour, firmness, external appearance, moisture accumulation in bags, total soluble solids, titratable acidity, browning, spoilage and sensory attributes at every 30 days interval up to 120 days. The physical and chemical parameters of fruits packed in StePac, Xtend® modified atmosphere/ modified humidity bags were maintained up to 90 days. Shrinkage and decay was noticed in Xtend® bags after 90 days of cold storage. Following Xtend® modified atmosphere/modified humidity and cold storage at 4±1°C pomegranate fruits can be stored up to 90 days at 4±1°C, maintaining the quality of the fruit compared to control and polypropylene packaging material.
