What is M.A.P?

Modified Atmosphere Packaging (M.A.P) is used to extend the shelf life of fresh food products. All foods e.g. red meat and bread, have different gas compositions. Red meat needs high levels of oxygen to maintain the red colour, vegetables usually need a three-gas mixture and bread require low levels of oxygen to avoid mould.

The main cause of the spoilage of food is the growth of microbes such as yeasts, bacteria and mould which are present all around us. These microbes cause the food to go bad because they feed and grow on the food product. When exposed to air, the appearance e.g. colour can change over time.

The low-temperature refrigeration will slow the growth of most microbes. Slowing the process of spoilage and keep the food edible and attractive for as long as it can. To keep food as fresh as possible without using additives is sealing the product in a package filled with a mixture of natural gases. These gases are controlled proportions which significantly slow down the decaying process.

Modified Atmosphere Packaging (Map-Pak) Analysers

Designed specifically for the Food Industry, the Modified Atmosphere Packaging (Map-Pak) food gas analysers measure the content of gas flushed food packaging. The Map-Pak range was developed as a quality device with a variety of features and can be used with minimal training.
The Map-Pak range was developed as quality control devices that have a range of features and can be used with minimal training. These lightweight portable analysers are easy to use in quality control functions and can be used for all food applications, as well as some applications in the pharmaceutical industry.
