Packaging is essential.
\nNevertheless, it is important to choose a type of packaging that minimises environmental impact.<\/strong><\/h3>\n

 <\/p>\n

Modified atmosphere packaging<\/strong> (MAP) is a technology for keeping food fresh. It involves replacing the natural ambient air in the packaging with a gas or gas mixture, often nitrogen and carbon dioxide.\u00a0 \u00a0This procedure ensures the quality of fresh produce over a longer period of time and at the same time extends shelf life in supermarkets. A wide range of products is gas flushed<\/strong>. Some typical products are e.g. fresh meat, coffee, ready meals, fruit & vegetables.<\/p>\n

Packaging under a protective atmosphere using the example of a potato chips bag: The manufacturer does not blow up the bags to make them look bigger, but to protect the food inside by the volume buffer<\/strong> and to make them last longer.<\/p>\n

To do this, they don't use \"normal\" air like we find all around us. This would not keep the food fresh because there is also oxygen in it, which makes the fat contained in it rancid. For a longer shelf life, pure nitrogen<\/strong> is used here.<\/p>\n

Depending on the food, other gases are used for protection.<\/p>\n

 <\/p>\n

For example, carbon dioxide<\/strong> is pumped into the bag of cut lettuce to prevent it from rotting, or oxygen<\/strong> is added to meat to keep it nice and pink.\u00a0 \u00a0In MAP technology<\/strong>, the normal air is first sucked out of the product packaging in a sterile environment and a so-called protective gas (e.g. O2, CO2, N2, CO, Ar, H2, He) is filled in instead.<\/p>\n

Gas sensors<\/strong> and controllers<\/strong> from MSR-Electronic provide reliable protection<\/strong> against gas leakage in the packaging industry.<\/p>\n

When packaging under modified atmosphere, it is crucial to ensure correct gas mixing<\/strong> as well as leak-free packaging. For most products, it is also important to set limits for the maximum and minimum residual oxygen content in the packages.<\/p>\n

For targeted gas monitoring, MSR-Electronic offers individual gas sensors and gas warning systems that detect toxic or combustible gas concentrations.<\/p>\n
