The color and polyphenol oxidase (PPO) activity of fresh-cut Golden delicious apples were evaluated throughout cold storage under modified atmospheres. The shelf life of cut apples was extended to several weeks, especially when an initial atmosphere of 90.5 N₂ + 7% CO₂ + 2.5% O₂ and plastic pouches of 30 cm³/c²• bar• 24 h were used. Under these condition, a maximum 62% PPO activity depletion was observed. In all cases, the faster the initial PPO activity decays, the less the color changes. A fractional conversion first-order model was proposed for predicting color changes in minimally processed apples. Browning was better described through lightness (L*) (kL=0.017-0.07 day⁻¹) and color difference (∆E*) values(k∆E = 0.015-0.073 day⁻¹) ), which fitted the modle with enough accuracy.
