<p>A packaging system and method utilized a modified atmosphere package (10) including an outer (12) and inner package (14). The outer package includes a non-barrier portion (16) substantially permeable to oxygen, while the inner packet (14) is substantially impermeable to oxygen. After a food product such as raw meat (26) is placed within the inner package (14), the inner package is sealed and then inserted into the outer package without sealing the outer package (12) so as to create a pocket (13) between the inner and outer packages. The system and method first employ an oxygen reduction technique such as evacuation, gas flushing, and/or scavenging to quickly reduce the oxygen level in the pocket to a first non-zero level, and to employ and activated oxygen scavenger (28) to further reduce the oxygen level to zero percent after the package (14) is sealed. The oxygen scavenger (28) is activated with an oxygen uptake accelerator to increase the rate at which the oxygen is absorbed. The oxygen scavenger (28) is positioned external to the inner package to aggressively absorb any residual oxygen with the pocket and the inner package and absorb any oxygen that might seep into the modified package (10).</p> |
