The perfect gas for every application

The main gases used in Modified Atmosphere Packaging (MAP) applications are carbon dioxide (CO2), nitrogen (N2) and oxygen (O2). These gases are used either alone or in combination.

The gas properties and the interaction of gases with the food ingredients, e.g. solubility in the foodstuff, should be taken into account when choosing the gas or gas composition. We supply food-grade CO2, N2, and O2 along with other gases authorized for foodstuffs as individual gases in cylinders under high pressure, liquids in insulated tanks for subsequent mixing at the packaging machine, and premixed.

“Food-grade gases” are defined as gases used as a processing aid and/or additive in order to ensure that standards are complied with. Our food-grade gases conform with “food-grade” regulations, e.g. the EC directive 96/77/EC on food additives within EU countries and the FDA guidelines in the U.S.

N2, and O2 are separated from atmospheric air. CO2 is taken from natural wells or captured as a byproduct of fermentation processes (wine, beer) or ammonia production, for example. Sometimes it may be more effective and practical to produce nitrogen on-site using PSA (pressure swing adsorption) or a permeable membrane plant. If a PSA/membrane system is used, a back-up gas supply system is recommended.
