Abstract : Mature mango fruits collected from 40-year-old trees were washed with tap water and then dipped in water (control), wax emulsion (6%) + captan (0.5%), or MH (2000 or 4000 p.p.m.) for 5 minutes. The fruits were then air dried and stored on wooden racks at room temperature (approximately 32 deg C). Wax emulsion treatment was the most effective in increasing storage life, for both cvs used, to 9-10 days compared with 6 days for the controls. Weight loss was greatest in the controls (14-15%) and was reduced to 4.2-7.3% by both wax emulsion and MH treatments. Ascorbic acid levels were unaffected by the treatments but were much higher in Langra fruit, which contained approximately 48 mg/100 g compared with 5 mg/100 g in the cv. Himsagar.
