ISO 17997-1|IDF 29-1:2004 specifies a reference method for the indirect determination of the casein-nitrogen content of bovine milk. It can be modified for milk from other species or liquid dairy products.
Abstract
Overview
ISO 17997-1:2004 (IDF 29-1:2004) defines a for determining the of bovine milk. The method precipitates casein at acid pH, measures the remaining (non‑casein) nitrogen, and calculates casein‑nitrogen as the difference from total nitrogen. It is a laboratory reference method intended for accurate, comparable results and can be modified for other milk species or liquid dairy products.
