Modified Atmosphere Packaging
In order to prevent loss of natural freshness and quality, an effective and intelligent food preservation concept called Modified Atmosphere Packaging (MAP) is used by Duni.
The use of natural gases together with proper packaging materials and machines help to maintain the quality of the food and prolong their shelf life. The MAP gas mixtures usually consist of the gases already present in the air that we breathe but in different compositions: carbon dioxide (CO2), nitrogen (N2) and oxygen (O2). The gas mixture is added before the trays are sealed.
Customers nowadays are more aware of quality than ever before. Thus, the demand for good, high quality, minimally processed and attractively packaged food is rapidly increasing. As a result, food manufacturers and producers have to work hard to meet this demand. People want freshly produced convenience food, often as smart ready-to-eat meals – as if they had been freshly prepared directly from the kitchen.
The race against time begins the moment fruit is picked, the corn is harvested or the fish is caught. From precisely that point on, natural deterioration and spoilage constitute a risk to the quality and shelf life of the food. Threats to product freshness, such as hygienic conditions while processing and temperature issues are things that must be taken into account. That is why the food packaging process as well as the package itself is crucial to freshness and quality.
By packaging food in a modified atmosphere, it is possible to maintain high quality and extend shelf life by days or even weeks. Products that could not previously be distributed or stored fresh throughout the distribution chain can now be put on the shelves at retail outlets without sacrificing quality.
