Nitrogen (E941) (N2) is colourless, odourless, tasteless, non-toxic and chemically inert gas.

Due to its low temperature, liquid nitrogen (E941) is widely used in food industry as a freezing agent and as a protection against the impact of microorganisms. Nitrogen (E941) extends the period of validity of food and maintains its nutrients and is also used for packing products. In other fields of industry, nitrogen (E941) is useful in suppressing the combustion processes and in creating protective environment in order to avoid oxidation.

Nitrogen (E941) is obtained from the atmospheric air by dividing it into composite parts. It meets the specific purity criteria laid down in EU Directive No. 231/2010. Nitrogen is filled in bright green coloured cylinders with black shoulder.

We offer to purchase nitrogen E941 in:

  • 5 l cylinders (0,96 m3, 200 bar);
  • 10 l cylinders (1,91 m3, 200 bar);
  • 20 l cylinders (3,9 m3, 200 bar);
  • 50 l cylinders (9,5 m3, 200 bar);
  • Cylinder bundles  12 x 50 l (114 m3, 200 bar);
  • Cylinder bundles  12 x 50 l (158 m3, 300 bar);
  • Dewars from 3 kg to … (subject to the volume of dewars);
  • Euro-cylinders from 230 l to 1,000 l.

We can fill the cylinders of other volumes as well. The clients buying a considerable amount of nitrogen (E941) are supplied with special storage tanks for the product and nitrogen (E941) is delivered with semitrailers.

Applications in the Food Industry:

Food preservation (MAP):
Protects products from oxidation and microorganisms, extends shelf life, and reduces vacuum effect in modified atmosphere packaging.

Refrigeration & freezing:
Ultra-low temperatures ensure rapid freezing, preventing large ice crystals and preserving food’s appearance, taste, and aroma.

Inerting & packaging stability: Displaces oxygen to protect product quality and helps plastic packaging maintain its shape, ideal for fragile goods.

Safety

If nitrogen (E941) pushes the oxygen necessary for breathing out of the air, it causes asphyxia (suffocation). Liquid nitrogen (E941) can cause cryogenic frostbites. More information on safe handling of nitrogen (E941) is provided in the material safety data sheet.
