When it comes to beverages, carbon dioxide (CO2) provides effervescence, a level of acidity and some protection against microbiological growth without the beverage looking, smelling or tasting strange, and without any undesirable levels of trace impurities.
The food industry also employs carbon dioxide for food processing applications, such as chilling and freezing, modified atmosphere packaging and temperature control for products being stored and transported.
But as we know, we obtain CO2 as a bi-product and it must therefore undergo effective purification for suitability as a direct food additive in beverages. Gas suppliers must identify, measure and control the levels of trace impurities in the purified CO2, and similarly, carbon dioxide users have a responsibility to take appropriate steps to ensure that suppliers have met this responsibility.
NOSA Testing’s methodologies and facilities for CO2 testing are now accredited, by SANAS under ISO 17025.
NOSA Testing is equipped to provide chemical testing for all CO2 methods, including the following:
| CO2 – 204 | Determination of total sulphurs in carbon dioxide (CO2), |
| CO2 – 205 | Determination of permanent gases in carbon dioxide (CO2) |
| CO2 – 208 | Determination of BTEX and hydrocarbons except 1-Butene in carbon dioxide (CO2) |
| CO2 – 209 | Determination of purity of carbon dioxide (CO2) by the Caustic Absorption Method |
