This standard specifies the characteristics of Mojonnier-type fat extraction flasks for use in gravimetric methods for the determination of fat in milk and milk products

The method in this Technical Specificiation specifies the calculation of the approximate content of phosphorus from added phosphate salts and phosphorus containing pH-regulating agents in processed cheese products

This standard specifies an enzymatic method for the determination of the lactose content of milk and reconstituted milk by measurement of the difference in pH (differential pH measurement)

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 by measurement of the absorptionThis 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.
