This International Standard specifies a method for the determination of the nitrate content of milk and milk
products by molecular-absorption spectrometry after Griess reaction (preceded by enzymatic reduction).
The method is, in particular, applicable to whole, partly skimmed, skimmed and dried milk, hard, semi-hard
and soft cheeses, processed cheese, whey cheese, caseins, caseinates, dried whey and milk protein
concentrates.
The method can be used at contents corresponding to a measured concentration in the sample solution (with
blank subtracted) of more than 0,2 mg/l.
