Milk and milk products - Determination of alkaline phosphatase activity - Part 1: Fluorimetric method for milk and milk-based drinks (ISO 11816-1:2024)
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 litre (mU/l). If the activity is higher than 7 000 mU/l, it is diluted with ALP-free milk so as to obtain a measurement not higher than 7 000 mU/l.

Lait et produits laitiers - Détermination de l'activité de la phosphatase alcaline - Partie 1: Méthode fluorimétrique pour le lait et les boissons à base de lait (ISO 11816-1:2024)
Le présent document spécifie une méthode fluorimétrique pour la détermination de l’activité de la phosphatase alcaline (ALP) (EC 3.1.3.1) dans les laits crus et traités thermiquement entiers, demi‑écrémés, écrémés et les laits aromatisés.
La méthode est applicable au lait et aux boissons à base de lait de vache, de brebis et de chèvre. Elle est également applicable au lait en poudre après reconstitution.
L’instrument utilisé pour la détermination de l’ALP peut lire des activités jusqu’à 7 000 mU/l (milliunités par litre). Si l’activité est supérieure à 7 000 mU/l, une dilution avec du lait exempt d’ALP est effectuée de façon à obtenir un mesurage ne dépassant pas 7 000 mU/l.
Mleko in mlečni izdelki- Določanje aktivnosti alkalne fosfataze - 1. del: Fluorimetrijska metoda za mleko in pijače na osnovi mleka (ISO 11816-1:2024)
Ta dokument določa fluorimetrijsko metodo za določanje aktivnosti alkalne fosfataze (ALP) (EC
3.1.3.1) v surovem in toplotno obdelanem polnomastnem, polmastnem in posnetem mleku in mleku z okusom.
Ta metoda se uporablja za mleko in pijače na osnovi kravjega, ovčjega in kozjega mleka. Uporablja se tudi za mleko v prahu po pripravi.
Instrument, ki se uporablja za določanje alkalne fosfataze, lahko beleži aktivnosti do 7000 milienot na liter (mU/l).
Če je aktivnost višja od 7000 mU/l, se razredči z mlekom brez vsebnosti alkalne fosfataze, da se pridobi meritev, ki ne presega 7000 mU/l.
