QUALITY CONTROL OF MODIFIED ATMOSPHERE PACKAGING (MAP)

Modified Atmosphere Packaging makes comparatively high demands on the packaging process, especially on the sealing process. Many sources of error can lead to leaks, usually micro-leaks. Right from the point of mixing the gases and introducing them into the package, maximum care is required. A faulty mixture or leaking packaging can have serious effects - from the loss of nutrients, taste, colour or structure to a bad smell or infestation with microorganisms. Depending on the product, health risks to the consumer cannot be completely eliminated.

Modified Atmosphere Packaging therefore requires modern high quality equipment and uncompromising standards of hygiene. But even when using best available technology, failures can’t be completely avoided. So comprehensive quality assurance activities are essential. These can begin during the packaging process, using inline gas analysis, which constantly monitors the composition of the modified atmosphere. After packaging, the packages must be tested for the correct gas mixture and for leaks.
