标准范围
This International Standard specifies a method for the determination of the nitrate content of milk and milkproducts 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-hardand soft cheeses, processed cheese, whey cheese, caseins, caseinates, dried whey and milk proteinconcentrates.The method can be used at contents corresponding to a measured concentration in the sample solution (withblank subtracted) of more than 0,2 mg/l.
