ISO 11868 | IDF 147: 2007 - Heat-treated milk - Determination of lactulose content - Method using high-performance liquid chromatography
|published date||24 March 2007|
|reference||ISO 11868, IDF 147: 2007|
This standard specifies a method for the determination of the lactulose content of heated milk, skimmed, partially skimmed or whole milk, by high-performance liquid chromatography, in order to distinguish milk sterilized by ultra-heat treatment (UHT) from in-bottle sterilized milk.
The method has been tested over a lactulose content range of 200 mg/l to 1 500 mg/l and is applicable to all heat-treated milks.
The method described is to be used in cases of dispute.
