Pineapples minimally processed were, stored eight days (5ºC and 85% RH) under passive and active atmosphere (MA). Neutral sugars, cellulose, hemicellulose, and total polyuronide analysis in cell wall were done. Two different active MA were tested: 5% of O2 + 5% of CO2 (MA1) and 2% of O2 + 10% of CO2 (MA2) and one passive MA (Control); during eight days of storage. Pineapples minimally processed stored under active modified atmosphere showed degradation of cell wall and less solubilization of hemicelluloses, besides being more effective in control of ethanol production and formation of off flavours. Pineapples minimally processed stored under modified atmosphere, showed life average of 6 days under refrigeration at 5ºC.
