Milk and milk products - Determination of alkaline phosphatase activity - Part 1: Fluorimetric method for milk and milk-based drinks
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. 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 can read activities up to 7 000 milliunits per litre (mU/l). If the activity is higher than
7 000 mU/l, it is diluted with alkaline phosphatase-free milk (7.1) so as to obtain a measurement not
higher than 7 000 mU/l.
