What is the purpose of modified atmosphere packaging?

The purpose of modified atmosphere packaging is primarily to inhibit oxidation and slow microbial growth. This packaging technique involves altering the composition of the gases in the package, typically by reducing the amount of oxygen and increasing levels of carbon dioxide and nitrogen. Oxygen can promote the growth of spoilage microorganisms and accelerate the degradation of food quality, including changes in flavor, color, and nutritional value. By creating a low-oxygen environment, modified atmosphere packaging effectively slows down spoilage processes, prolonging the shelf life of food products while maintaining their quality.

This method is particularly useful for perishable items such as meats, fruits, and ready-to-eat meals, where freshness and safety are critical. Enhanced shelf life not only benefits consumers by providing longer-lasting products but also helps reduce food waste at various stages of the supply chain.
