Abstract : Mango cv. Bullock's heart fruits were dipped in 1 or 2% calcium chloride solution for 5 minutes or 4, 6 or 8% wax emulsion or individually wrapped in low density polyethylene film (LDPE) before packing them in one layer in carton boxes. Dipping in 8% wax emulsion resulted in the lowest weight losses and highest acidity of the fruits, whereas individual wrapping of fruits in LDPE resulted in the highest carotenoid content. Postharvest decay were not observed in fruits dipped in 2% calcium chloride or 85% wax emulsion. Flesh firmness was highest in fruits dipped in 2% calcium chloride. Among the treatment, dipping in 4% wax emulsion resulted in the highest total sugar content of the fruits, although the values obtained were lower than those of the control fruits.
