The objective of this work was to evaluate the effects of cassava starch and corn starch biofilm on the postharvest conservation of ‘Tommy Atkins’ mangos. The fruits were selected, washed, disinfected and coated with cassava starch and corn starch biofilm in the concentrations of 2%, 4% and 6%, and stored for 21 days at 12 ± 0.6ºC and 86 RH, plus an additional period of 7 days at 21 ± 2ºC and 67% RH. The effects of the treatments were evaluated by mass loss, maturation index, pulp firmness, total soluble solids content, titratable acidity and pH. The experiment was carried out in a completely randomized design in 7x4 factorial scheme (treatments x storage periods), with four replications. The results indicate that the use of cassava starch at 2%
and corn starch biofilms at 4% reduced the mass loss, maintained the firmness, improved the visual aspects and prolong the storage period without decreasing the fruits quality.
