The objective of this study was to evaluate the physical, physico-chemical and microbiological stability of dried organic banana varieties Caipira, Pacovan Ken and Prata Anã, 180 days of storage, as well as adjust the drying curves . The bananas were dried in an oven with forced air circulation at 65 ° C until final humidity of 20-25 % ( wb). The variety Pacovan Ken reached the final moisture after 37h of dehydration . The value of water activity for the three varieties, remained stable at 180 days and features the product as intermediate moisture. Not observed in any treatment, significant variation of physico-chemical analysis of variance parameters. There darkening of the product in all three varieties, with a significant loss of brightness (L*) and the intensity of the yellow color (b*) and increased intensity of red color (a*) during storage. There was microbiological stability of the product, with low count of yeasts and molds and Salmonella and coliforms at 35°C in all varieties, according to current legislation. The dried organic banana trade showed stability in the months of study.
