Modified Atmosphere Packaging (MAP) is the new buzz word in food packaging. MAP is becoming more and more popular for preserving the freshness and extending the storage/shelf life of fresh fruits, vegetables, meats, dairy products, and many more.

What is MAP technology?

According to Wikipedia, “Modified atmosphere is the practice of modifying the composition of the internal atmosphere of a package (commonly food packages, drugs, etc.) in order to improve the shelf life. The need for this technology for food arises from the short shelf life of food products such as meat, fish, poultry, and dairy in the presence of oxygen. In food, oxygen is readily available for lipid oxidation reactions. Oxygen also helps maintain high respiration rates of fresh produce, which contribute to shortened shelf life. From a microbiological aspect, oxygen encourages the growth of aerobic spoilage microorganisms. Therefore, the reduction of oxygen and its replacement with other gases can reduce or delay oxidation reactions and microbiological spoilage.

The modification process generally lowers the amount of oxygen (O2) in the ...
... headspace of the package. Oxygen can be replaced with nitrogen (N2), a comparatively inert gas, or carbon dioxide (CO2). A stable atmosphere of gases inside the packaging can be achieved using active techniques, such as gas flushing and compensated vacuum, or passively by designing “breathable” films.’

To package a product in a modified atmosphere requires sophisticated machinery to flush out air from the packaging chamber and replace it with a different gas or precisely defined mixture of gases, then seal the product in the packaging so that only the modified atmosphere surrounds the product and not any other unwanted gas.

Cutting edge technologies have been developed to ensure that the gas mixture is the correct one, and to test that once sealed, the packages contain the right mixture and do not leak.
