ISO 22160 | IDF 209: 2007 - Milk and milk-based drinks - Determination of alkaline phosphatase activity - Enzymatic photo-activated system (EPAS) method
|published date||24 March 2007|
|reference||ISO 11868, IDF 147:2007|
This standard specifies a method for the determination of the alkaline phosphatase activity in pasteurized whole milk, semi-skimmed milk, skimmed milk, cream and flavoured milks using a chemiluminescent (EPAS) method.
The method is applicable to milk and milk-based drinks from cows, sheep, buffalo and goats.
The method is also suitable for any liquid-based sample if diluted in such a way that the diluted alkaline phosphatase activity has less than 7 000 milliunits per litre.
