Ethylene triggers the ripening process of tomato affecting the storage durability and shelf life (loss ofquality) and inducing fruit decay. In this paper, an active packaging has been developed on the basisof the combination of modified atmosphere packaging (MAP) and the addition of granular-activatedcarbon (GAC) alone or impregnated with palladium as a catalyst (GAC-Pd). A steady-stateatmosphere was 4 and 10 kPa for O₂ and CO₂ in control packages, while it was 8 and 7 kPa for O₂and CO₂ in treated ones. The addition of GAC-Pd led to the lower ethylene accumulation insidepackages, while the higher was obtained in controls. The parameters related to ripening showed thattreated tomatoes exhibited a reduction in color evolution, softening, and weight loss, especially forGAC-Pd treatment. Moreover, these treatments were also effective in delaying tomato decay. Aftersensorial panel, tomatoes treated with GAC-Pd received the higher scores in terms of sweetness,firmness, juiciness, color, odor, and flavor. Results from the GC-MS analysis of the MAP headspaceshowed that 23 volatile compounds were identified in control packages, with these volatiles beingsignificantly reduced in MAP-treated packages, which was correlated to the odor intensity detectedby panelists after bag opening.Keywords: Active packaging; volatile compounds; decay; ethylene adsorber; MAP
