Oxygen (E948) (O2) is a gas that is vitally important to each organism. It is odourless, colourless and tasteless gas. Liquid oxygen (E948) is characterised by light-blue colour.

In food industry, oxygen is usually removed from the packages, because it causes the deterioration of food products, fast proliferation and growing of various microorganisms. However, in case of choice of a precise concentration of oxygen, it is possible to achieve positive results – to maintain a marketable appearance and colour of a product and to suppress the growing of certain anaerobic microorganisms.

Oxygen (E948) 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. Oxygen (E948) is filled in green cylinders with white shoulder, dewars, euro-cylinders and other cryogenic tanks.

We offer to purchase food grade oxygen (E948) in:

  • 10 l cylinders (2,11 m³, 200 bar);
  • 50 l cylinders  (10,7 m3, 200 bar);
  • 12 x 50 l Cylinder bundles (128,4 m3, 200 bar);
  • Dewars from 5 kg to … (subject to the volume of dewars);
  • Euro-cylinders from 230 l to 1,000 l;
  • Liquid oxygen (in tons).

We can fill the cylinders of other volumes as well. The clients buying a considerable amount of oxygen (E948) are supplied with special storage tanks for the product and oxygen (E948) is delivered with semitrailers.

Oxygen (E948) maintains the natural colour of food products, i.e. oxidises myoglobin (red pigment of raw meat). Oxygen maintains the “breathing” of fruits and vegetables and suppresses the growing of anaerobic microorganisms in certain fish products and vegetables.



The increase of oxygen concentration by just a few percentage points causes a risk of fire. The sparks that are usually considered as non-hazardous may cause fires, whereas the substances that are non-combustible in the air, including the substances used for the protection from fire, can be highly combustible or even flame up spontaneously in the air filled with oxygen. More information on safe handling of oxygen is provided in the material safety data sheet.
