Modified Atmosphere Packaging (MAP) is a preservation technique that replaces the natural air inside a package with a controlled gas mixture to extend shelf life, maintain freshness, and prevent spoilage. It works by adjusting the levels of oxygen (O₂), carbon dioxide (CO₂), and nitrogen (N₂) to slow microbial growth, oxidation, and moisture loss.
For meat products, reducing oxygen levels helps prevent discoloration, spoilage, and bacterial growth, while carbon dioxide inhibits microbial activity. Dairy products, such as milk and yogurt, benefit from MAP by minimizing exposure to oxygen, which slows spoilage and maintains taste. Cheese packaging often uses MAP to control moisture levels, prevent mold formation, and preserve texture and flavor.
MAP is widely used with vacuum-sealed pouches, nitrogen-flushed bags, and resealable stand-up pouches, ensuring products remain safe, fresh, and visually appealing for longer periods. This packaging method helps reduce food waste, improve product presentation, and enhance overall quality in dairy, meat, and cheese packaging.
