Abstract : Biofilms have been evaluated as an option to attain a modified atmosphere leading to longer shelf life and better appearance of fruits and vegetables. This work aimed to evaluate the use of biofilms with sunflower oil for quality maintenance of 'Tommy Atkins' mango fruit under 27.9°C+1.5°C; 64.6%+3% R.H. Fruits were treated with a one-minute dip in suspensions (treatments) based on cassava starch or maize starch at 1%, 2% or 3%, containing sunflower oil at 0.05%. Control fruits were not treated with biofilm. Fruits were evaluated every four days over 16 days for: mass loss, skin and pulp color, pulp firmness, soluble solids (SS), titratable acidity (AT), SS/AT ratio and pH. Biofilms based on cassava starch delayed fruit ripening for at least four days in comparison to non-treated fruits. The treatments reduced weight loss and delayed the external color evolution and the increase in SS/AT ratio, keeping the fruits more acid when compared to the control. It could be concluded that the biofilms with sunflower oil at 0.05%, mainly those based on cassava starch at 1% to 3%, helped the quality maintenance of 'Tommy Atkins' mango fruit, without damages to quality attributes.
