Abstract
The effect of different levels of potassium permangenate (KMnO4) on quality of mango fruits were studied over a period of 21 days. A factorial trial in the form of complete randomized design as three levels of KMnO4 (0, 5 or 10 g. kg-1 fruit) and three time period (7, 14 or 21 days) was used. Means were compared using Duncan’s test (P< 0.05). Compositional parameters (pH, acidity, total soluble solids, density, ascorbic acid and phenolics in pulp and skin) were measured during storage time. Results showed that after application of -the highest level of -KMnO4 (10 g.kg-1 fruit), treated fruits had significantly higher acidity after 7 days. Fruits that treated with 10 g of KMnO4 had significantly higher phenolics in pulp after 7 days, but phenolics deceased significantly over control after 21 days. Phenolic compounds in fruit skin significantly (P
