This present study aimed to evaluate the effect of modified atmosphere (MA) by the use of plastic packaging for low density polyethylene (LDPE), the vacuum and the adsorption of ethylene, aiming the maintenance of the quality of bananas 'Prata Anã' cultived in Roraima.. Analyses were performed each 5 days after harvest, up to 35 days. It was verified that the fruit under LDPE bags showed the lowest losses of fresh weight when compared to the others. Likewise, as the fruits packed in the presence of ethylene adsorption sachet had the best maintenance in the color peel, delay of the climacteric peak, as the delay in the starch degradation, lowest increments of soluble solids and titratable acidity, the lowest concentration of ethylene inside the LDPE bags and delay and decrease of enzyme activity. The combination of the use of LDPE bags with the sachet of potassium permanganate (KMnO4) resulted in the delay of ripening fruits of bananas 'Prata Anã', when stored at 12 ºC. It can be attributed this beneficial effect by the presence of the sachet in the adsorption of ethylene and, consequently, in the action of ethylene in the fruit ripening, delaying the senescence of bananas 'Prata Anã'.
