Milk and milk products - Determination of alkaline phosphatase activity - Part 2: Fluorimetric method for cheese (ISO 11816-2:2024)
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 read activities in the supernatant up to 7 000 milliunits per litre (mU/kg).

Lait et produits laitiers - Détermination de l'activité de la phosphatase alcaline - Partie 2: Méthode fluorimétrique pour le fromage (ISO 11816-2:2024)
Le présent document spécifie une méthode fluorimétrique de détermination de l’activité de la phosphatase alcaline (ALP) (EC 3.1.3.1) dans le fromage.
La présente méthode est applicable aux fromages à pâte molle, pâte pressée non cuite et pâte pressée cuite, à condition que la moisissure ne soit présente que sur la surface du fromage et ne se soit pas propagée à l’intérieur, comme dans le cas des fromages veinés de bleu, par exemple. Pour les gros fromages à pâte pressée cuite, des conditions d’échantillonnage spécifiques s’appliquent (voir l’Article 7).
L’instrument utilisé pour la détermination de l’ALP peut lire des activités jusqu’à 7 000 mU/kg (milliunités par kilogramme).
Mleko in mlečni izdelki - Določanje aktivnosti alkalne fosfataze - 2. del: Fluorometrijska metoda za sir (ISO 11816-2:2024)
Ta dokument določa fluorimetrijsko metodo za določanje aktivnosti alkalne fosfataze (ALP)
(EC 3.1.3.1) v siru.
Ta metoda se uporablja za topljene, poltrde in trde sire pod pogojem, da je plesen samo na površini sira, in ne tudi na notranji strani (npr. sir z modrimi plesnimi). Za velike trde sire veljajo posebni pogoji vzorčenja (glej točko 7).
Instrument, ki se uporablja za določanje alkalne fosfataze, lahko beleži aktivnosti v supernatantu do 7000 milienot na liter (mU/kg).
