A modified atmosphere package includes first and second compartments separated by a partition member that is substantially permeable to oxygen. The first compartment contains an oxygen scavenger activated with an oxygen scavenger accelerator. The second compartment contains a retail cut of raw meat. Various techniques are employed to rapidly reduce the oxygen level in the second compartment below pigment sensitive levels so that the growth of metmyoglobin is inhibited. Some of these techniques increase the flow of oxygen from the second compartment to the first compartment through the partition member, while other techniques directly absorb oxygen within the second compartment.
L'invention porte sur un conditionnement (10) sous atmosphère modifiée comprenant des premier et second compartiments séparés par une cloison pratiquement perméable à l'oxygène. Le premier compartiment contient un désoxygénant (28) activé par un accélérateur. Le second compartiment contient une tranche de viande désossée (26). Diverses techniques sont utilisées pour réduire rapidement la teneur en oxygène du second compartiment en dessous de taux réagissant aux pigments de façon à inhiber la formation de la metmyoglobine. Certaines de ces techniques augmentent le flux d'oxygène s'écoulant du second au premier compartiment par la cloison, alors que d'autres techniques absorbent directement l'oxygène dans le second compartiment.
