Weight loss in mangos occurs during storage due to transpiration (Policegoudra and Aradhya, 2007) and water evaporated from the peel. This leads to a decrease in the fruits’ commercial value. It has been reported that once the weight loss reaches 10%, mangos shrivel and lose their fresh taste. As shown in Fig. 2(b), the weight loss of the CK group was the largest, followed by group A with group B having the smallest. The best explanation links this observation to the coating’s physical barrier action. Water evaporation was reduced because of the coating covering the mango’s surface. The results showed the coating of group B provided better protection against moisture due to the loading of potassium sorbate. In
other words, the mango’s taste is preserved because water is kept in the fruit.
