Abstract : Sapburn injury caused by latex is one of the main post-harvest problems affecting the quality of mango (Mangifera indica) fruits. It causes dark and superficial stains in the peel of the fruit. Thus, with the objective of controlling the sapburn injury caused by latex in mango cv. Tommy Atkins, a pellicle of cassava starch was applied in the pre-harvest phase, at concentrations of 0, 2, 4 and 6%. Analyses of pH, soluble solids, titratable acidity, loss of fresh mass and damage index were performed. For sapburn injury evaluation, an index scale varying from 0 to 3, where 0=absence of damage; 1=light damage; 2=moderately severe damage; 3=severe damage was used. During the storage period, there was an increase in the concentration of sugars and a decrease in titratable acidity that altered the pH of the pulp and reduced the final fruit weight. The cassava starch biofilm had a partially satisfactory effect in reducing sapburn injury.
