Ask the Expert

Why is carbon dioxide used in Modified Atmosphere Packaging (MAP)?

Carbon dioxide (CO₂) inhibits the growth of most aerobic bacteria and moulds. Generally speaking, the higher the level of CO₂, the longer the achievable shelf-life. However, CO₂ is readily absorbed by fats and water - therefore, most foods will absorb CO₂. Excess levels of CO₂ in MAP can cause flavour tainting, drip loss and pack collapse. It is important, therefore, that a balance is struck between the commercially desirable shelf-life of a product and the degree to which any negative effects can be tolerated. When CO₂ is required to control bacterial and mould growth, a minimum of 20% is recommended.
