Study of the Use of Edible Waxes and Storage Conditions in the Preservation of Mangoes (Mangifera indica L.)

The mango (Mangifera indica L.) is a highly perishable fruit, with mass loss and visual deterioration being limiting factors for commercialization.The objective of this study was to evaluate the effect of carnauba wax-and beeswax-based coatings, with or without refrigerated storage, on postharvest preservation.The experiment was conducted using a completely randomized design in a 3 × 2 factorial layout, with three coating treatments (control, carnauba wax, and beeswax) and two storage conditions (room temperature and refrigerator).Five evaluations were performed throughout the experimental period, assessing mass loss, firmness, color, gloss, and appearance.The mass loss data were subjected to statistical analysis, while the other variables were analyzed descriptively.The results indicated that refrigerated storage significantly reduced fruit mass loss compared to room temperature storage, regardless of the type of coating used.For the mass loss variable, the "Carnauba Wax + Refrigerator" treatment stood out.The evaluations of firmness, color, gloss, and appearance did not reveal significant visual or tactile differences among the coatings under the same storage conditions, making it inconclusive as to the specific effect of the waxes.
