ISO 11816-2 | IDF 155-2: 2024 - Milk and milk products — Determination of alkaline phosphatase activity — Part 2: Fluorimetric method for cheese Publication Type - World Dairy Situation Report The colony-count technique (spread plates)This document specifies a fluorimetric method for the determination of alkaline phosphatase (ALP) (EC 3. 1. 3. 1) activity in cheese. This method is applicable to soft cheeses, semi hard and hard cheeses provided that the mould is only on the surface of the cheese and not also in the inner part (e. g. blue veined cheeses). For large hard cheeses, specific conditions of sampling apply (see Clause 7). The instrument used for the determination of ALP can
