Resumen:
This part of ISO 11816/IDF 155 specifies a fluorimetric method for the determination of alkaline phosphatase (ALP, EC 3.1.3.1) activity in raw and heat-treated whole milk, semi-skimmed milk, skimmed milk and flavoured milks. The method is applicable for milk and milk-based drinks from cows, sheep and goats. It is also applicable to milk powder after reconstitution. The instrument can read activities of up to 7000 milliunits per litre (mU/l). If the activity is higher than 7000 mU/l, it is diluted with alkaline phosphatase-free milk so as to obtain a measurement not higher than 7000 mU/l.
