Storage Life of Pork Chops in CO-Containing Atmospheres .

Pork chops were packaged in a controlled atmosphere (10% CO/79% N/1% O, 30% CO/68% N/2% O, 30% CO/70% N, 100% CO or air) and then stored at either 2 or 5 C. Changes in gas composition, microbiological counts and sensory quality were monitored after 0, 9, 12, 16, 19, 23, 30 and 37 days of storage. Two chops from each treatment were stored additionally under retail-like conditions for 3 and 5 days.
