Bibliography
ISO 22160|IDF 209:2007 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.
