Abstract : The effects of modified atmosphere and plastic films with cold storage on 'Haden 2H' mango fruit quality were studied. Fruits were packed in low density polyethylene (with and without potassium permanganate absorber) and PVC [poly(vinyl chloride)] bags and then stored for 28 days at 12°C and 90% relative humidity. Every week, the bags were removed and mangoes were transferred to 25°C to simulate commercialization. Quality parameters (total soluble solids, acidity, firmness, flesh and peel colour) and losses (weight loss and rots) were evaluated immediately after cold storage and when the mangoes ripened at room temperature. Polyethylene film decreased fruit weight losses during storage. Packing had no effect on peel and flesh colour, firmness and disease incidence in mangoes during storage. The shelf life of 'Haden 2H' mangoes was 21 days due to disease development.
