Milk and milk products - Determination of alkaline phosphatase activity - Part 2: Fluorometric method for cheese (ISO 11816-2:2016)
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 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 can read activities in the supernatant up to 7 000 milliunits per litre (mU/l).
Milch und Milchprodukte - Bestimmung der Aktivität der alkalischen Phosphatase - Teil 2: Fluorimetrisches Verfahren für Käse (ISO 11816-2:2016)
Dieser Teil von ISO 11816 | IDF 155 legt ein fluorimetrisches Verfahren für die Bestimmung der Aktivität der alkalischen Phosphatase (ALP, EC 3.1.3.1) in Käse fest.
Dieses Verfahren gilt für Weichkäse, Schnittkäse und Hartkäse unter der Voraussetzung, dass der Schimmel nur an der Käseoberfläche und nicht auch im Innern des Käses vorhanden ist (z. B. Gorgonzola).
Das Gerät kann Aktivitäten im Überstand von bis zu 7 000 Milliunits je Liter (mU/l) auslesen.
ANMERKUNG In großen Hartkäselaiben, bei denen das Gemisch aus Bruch und Molke auf Temperaturen von über 50 °C eingestellt wird, bleiben diese hohen Temperaturen besonders in der Mitte der Käselaibe für relativ lange Zeit bestehen, die die Inaktivierung der Phosphatase fördern. Zur Bestimmung der Aktivität der alkalischen Phosphatase in dieser Art von Käse muss eine spezifische Probenahmetechnik für Käse (siehe Abschnitt 6) angewendet werden.
Lait et produits laitiers - Détermination de l'activité de la phosphatase alcaline - Partie 2: Méthode fluorimétrique pour le fromage (ISO 11816-2:2016)
L'ISO 11816-2 :2016|FIL 155-2 :2016 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 permet de détecter des activités dans le surnageant de l'ordre de 7 000 milliunités par litre (mU/l).
Mleko in mlečni proizvodi - Določevanje aktivnosti alkalne fosfataze - 2. del: Fluorometrijska metoda za sir (ISO 11816-2:2016)
Ta del standarda ISO 11816|IDF 155 določa fluorometrijsko metodo za določevanje 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 v njegovi notranjosti (npr. sir z modrimi plesnimi). Za velike trde sire se uporabljajo posebni pogoji vzorčenja (glej točko 7).
Instrument lahko beleži aktivnosti v supernatantu do 7000 milienot na liter (mU/l).
