Modified atmosphere packaging (MAP) using food gas mixtures is a cutting-edge solution that significantly extends the shelf life of food products. It ensures sterile storage conditions while eliminating the need for harmful preservatives — all made possible by modern packaging equipment and the correct choice of gas composition.
Why use food gas mixtures?
All food — whether fresh produce or processed goods — gradually deteriorates. Even popular items like smoked meats, cheeses, or fruits lose freshness, develop mould, or change in flavour over time.
To extend product shelf life, food manufacturers often turn to:
- Chemical preservatives
- Vacuum packaging
- MAP with food-safe gas blends
Preservatives, while common, may pose health risks due to potential carcinogenic content. Vacuum packaging removes oxygen, reducing the chance for microbial growth. However, food gas mixtures go further, offering added benefits.
Key benefits of food gas mixtures:
- Antibacterial effect
- Inhibition of mould and pathogenic microorganisms
- Acidity control
- Stimulation of plant growth in greenhouse agriculture
Compared to conventional preservation techniques like thermal treatment or simple gassing, MAP provides a more precise and technology-driven approach tailored to each product’s specific needs.
How it works
Modified atmosphere packaging adjusts the balance of atmospheric gases — mainly nitrogen (N₂), oxygen (O₂), and carbon dioxide (CO₂) — depending on the product:
- CO₂ suppresses mould and bacterial growth (ideal for meats and baked goods)
- N₂ displaces oxygen to maintain internal pressure and packaging integrity
- O₂ helps preserve freshness colour, especially for fruits, vegetables, and greens
