Product Description

This International Standard specifies a method for the determination of the nitrogen content and crude protein calculation of milk and milk products by the Kjeldahl principle, using traditional and block digestion methods.

The methods are applicable to:

— liquid cow’s (whole, partially skimmed or skimmed milk), goat’s and sheep’s whole milk;

— hard, semi-hard and processed cheese;

— dried milk and dried milk products (including milk-based infant formulae, milk protein concentrate, whey protein concentrate, casein and caseinate).

The methods are not applicable to samples containing ammonium caseinate.

NOTE Inaccurate crude protein results will be obtained if non-milk sources of nitrogen are present in the products specified in this International Standard.

This second edition of ISO 8968 1|IDF 20-1 cancels and replaces the first edition of ISO 8968 1| IDF 20 1:2001, ISO 8968 2|IDF 20 2:2001, ISO 5549:1978/ IDF 92:1979 and ISO/TS 17837| IDF/RM 25:2008 which have been technically revised.
