Modified atmosphere packaging (MAP) is a technique used to extend the shelf life of food products. It involves altering the composition of gases surrounding the food inside its packaging. Typically, the oxygen level is reduced, while nitrogen and carbon dioxide are increased, which helps slow down spoilage and maintain freshness. This method is commonly used for various products, including fruits, vegetables, and meat. By controlling the atmosphere, MAP helps prevent the growth of bacteria and mold, ensuring that food remains safe and appealing for a longer period.
