Our food grade gases conform with Commission Regulation (EU) No 231/2012 of 9 March 2012 laying down specifications for food additives listed in Annexes II and III to Regulation (EC) No 1333/2008 of the European Parliament and of the Council.
The main gases used in Modified Atmosphere Packaging (MAP) applications are carbon dioxide, nitrogen and oxygen. 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 carbon dioxide (CO 2) , nitrogen (N 2), and oxygen (O 2) along with other gases authorised for foodstuffs as individual gases in cylinders under high pressure as well as liquids in insulated tanks for subsequent mixing at the packaging machine and premixed.
Nitrogen and oxygen are separated from atmospheric air. Carbon dioxide is taken from natural wells or captured as a by-product of fermentation processes (wine, beer) or ammonia production. For example, sometimes it may be more effective and practical to produce nitrogen on-site using pressure swing absorption (PSA) or a permeable membrane plant.
Linde can help determine the correct method for you.
Advantages for the User:
- High purity gas
- Consistently high quality
We are also able to supply gases to you for chilling and freezing in liquid form including liquid nitrogen (LIN), liquid carbon dioxide (LIC) and carbon dioxide in a solid state as snow (dry ice).
