Modified Atmosphere Packaging

Why use Modified Atmosphere Packaging
Modified atmosphere packaging dramatically extends the quality and shelf life of packaged food products. It ensures the food keeps its flavour, texture, appearance and nutritional value for a longer period, benefiting not only the consumer and the food producer, but also the distributor and the retailer.

How does Modified Atmosphere Packaging work
Modified Atmosphere Packaging or MAP works by modifying the composition of the gases within packaged food products or pharmaceuticals, replacing the air with either a single gas or a mixture of gases. This specifically tailored atmosphere slows down the chemical deterioration and the spoilage organisms within the food package.

The gas mixture used to replace the air is dependent on the type of food being packaged, packaging materials and storage temperature. It will generally consist of a mixture of N₂, O₂ and CO₂. It is the distorted ratio of these gases that makes the difference in the prolongation of shelf life.
