Examples of typical MAP materials
For selected raw, reddish poultry, the principal spoilage mechanisms are aerobic microbial growth and oxidation of the red pigment to its brown oxidised form.
Aerobic spoilage bacteria, particularly Pseudomonas species, are very effectively inhibited by inclusion of CO₂ in MAP. High concentrations of O₂ are necessary to maintain the desirable red colour of raw, reddish poultry products for a longer period.
To create the dual effect of red colour stability and microbial inhibition, a gas mixture containing 70% O₂ and 30% CO₂ is recommended. A gas/product ratio of 2:1 is recommended. The Achievable shelf-life of MA packed raw, reddish poultry products will depend on the species, fat content, initial microbial load, gas mixture, and temperature of storage.
Possible food poisoning risks can be minimised by maintenance of recommended chilled temperatures, good hygiene and handling practices throughout, and adequate cooking prior to consumption.
* The Food Safety (Temperature Control) regulations 1995 states that the maximum Storage temperature for chilled perishable foods is 8°C. There will be flexibility to vary this when scientifically justified. For legal temperature storage requirements, please contact the Campden and Chorleywood Food Research Association.
