FOOD-GRADE NITROGEN

Purity verification as required by European Regulation No. 231/2012.

Request a consultation

EU Regulation 231/2012 defines nitrogen as a food additive and specifies the purity requirements it must meet.

Residual humidity

We measure humidity to prevent corrosion and ensure gas stability during use.

Gaseous contaminants

We measure concentrations of O2, CO, NO, NO2, as required by EU Regulation 231/2012.

Hydrocarbon residues

We verify the presence of hydrocarbons that could contaminate food and alter its organoleptic qualities.

All analyses are carried out with UNI methods and calibrated instrumentation, according to good laboratory practices.

At the end of the tests, a test report will be issued indicating the nitrogen purity and any measured impurities.

Aria Alimentare - Food-grade nitrogen analysis

LIMIT VALUES DEFINED BY EU REGULATION 231/2012

Below are the analyzed parameters with their respective maximum limits allowed for nitrogen used in the food industry:

Parameter	Limit value
WATER	No more than 0.05%
CARBON MONOXIDE	No more than 10 µl/l
METHANE AND HYDROCARBONS	No more than 100 µl/l
NITROGEN DIOXIDE AND OXIDE	No more than 10 µl/l
OXYGEN	No more than 1%

Conformity verification is carried out in reference to European Regulation 231/2012, which establishes the specifications of food additives listed in Annexes II and III of Regulation EC No. 1333/2008.
