Summary

Gas exchange modified atmosphere packaging (GEMAP) with display gas of 80% O2:20% CO2 retarded microbial growth and improved colour stability of ground beef patties compared with vacuum packaging (VP) followed by air-permeable polyvinylchloride (PVC) overwrapping during 3 days of retail display. Predominant microorganisms for GEMAP were Pseudomonas, Yersinia, Aeromonas , and Enterobacter and for VP-PVC were Pseudomonas, Brochothrix, Aeromonas, Enterobacter, Moraxella, and Lactobacillus. Lower levels of pathogens were isolated in GEMAP samples with 7 than 15 °C display temperature. Patties were darker with those with 15 than with 7 °C display and redder in GEMAP than VP-PVC. Good manufacturing practices should be followed with MAP meat to reduce the risk of pathogenic microbial growth.
