ISO 20541 | IDF 197: 2008 - Milk and milk products - Determination of nitrate content - Method by enzymatic reduction and molecular-absorption spectrometry after Griess reaction Publication Year - 2013 This standard specifies a method

This standard specifies a method for the determination of the total milk-clotting activity of an ovine or caprine rennet

This standard gives general guidance for the recruitment

unless otherwise agreed by the interested parties

It provides criteria for the acceptability of differences between the results from parallel plates and subsequent dilution steps

ISO 20541 | IDF 197: 2008 - Milk and milk products - Determination of nitrate content - Method by enzymatic reduction and molecular-absorption spectrometry after Griess reaction Publication Year - 2013 This standard specifies a methodThis 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
