ISO 11816-1 | IDF 155-1: 2024 - Determination of alkaline phosphatase activity — Part 1: Fluorimetric method for milk and milk-based drinks Publication Year - 2010 molybdenum (Mo) and selenium (Se)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 7 000 milliunits per
