Packaging in Modified Atmosphere Packaging (MAP) with a high content of oxygen (high Ox MAP) is becoming common for retail display. High Ox MAP results in a red colour and increased shelf life, however, it also reduces the organoleptic quality. A drawback about non-oxygen MAP is the colour of the meat, which becomes purple like vacuum-packed meat.

DMRl has worked on developing a tri-gas solution to overcome the dilemmas observed with the traditional two-gas solution. The aim of this project is therefore to document how the new tri-gas solution affects shelf life and organoleptic quality of exported Australian beef.
