What is modified air packaging?

Modified atmosphere packaging (MAP) is a technique used to extend the shelf life of perishable products by altering the composition of the internal atmosphere of the packaging. This typically involves reducing oxygen levels and increasing carbon dioxide and nitrogen concentrations to slow microbial growth and oxidation. The modified atmosphere helps preserve the freshness, color, and flavor of food products, making it popular in the packaging of meats, fruits, and vegetables. MAP can significantly enhance product durability while maintaining quality.
