Modified atmosphere packaging

As soon as it comes into contact with air, the color, appearance, texture, taste and shelf life of food start to deteriorate. Modified atmosphere packaging, or MAP, helps to slow down these changes. Air Liquide has developed a special range of products and solutions for MAP applications and has the expertise its customers need to keep food products fresh and safe.

Modified atmospheric packaging at a glance

Modified atmospheric is a process for packaging food products together with a gas or gas mixture that replaces air inside the package and provides protective and reactive properties. When combined, the gas and the packaging help to prevent microbial, enzymatic and physical deterioration in order to maintain the initial taste and quality of a food product. MAP enhances the color and appearance of food, preserves the product's shelf life, and protects food from harmful bacteria.

Our gas solutions

Air Liquide offers a range of food grade gases. As the industry benchmark, our ALIGAL™ gases meet HACCP (Hazard Analysis Critical Control Point) standards for production and logistics of gases dedicated to the food and beverage industry. HACCP is a system which identifies, evaluates and controls hazards which are significant to food safety. Our ALIGAL™ gases adhere to strict quality specifications and go beyond standard regulatory requirements. This ensures traceability along the gas supply chain.

We leverage our historical know-how in MAP applications to work closely with our customers in determining the right gas mixture for their products.
