| Resumen: | This document 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. This method is applicable to milk and milk-based drinks from cows, sheep and goats. It is also applicable to milk powder after reconstitution. The instrument used for the determination of ALP can read activities up to 7000 milliunits per litre (mU/l). If the activity is higher than 7000 mU/l, it is diluted with ALP-free milk so as to obtain a measurement not higher than 7000 mU/l. |
