Milk and milk-based drinks - Determination of alkaline phosphatase activity - Enzymatic photo-activated system (EPAS) method (ISO 22160:2007)

ISO 22160|IDF 209:2007 specifies a method for the determination of the alkaline phosphatase activity in pasteurized whole milk, semi-skimmed milk, skimmed milk, cream and flavoured milks using a chemiluminescent (EPAS) method.
The method is applicable to milk and milk-based drinks from cows, sheep, buffalo and goats.
The method is also suitable for any liquid-based sample if diluted in such a way that the diluted alkaline phosphatase activity has less than 7 000 milliunits per litre.

Milch und flüssige Milcherzeugnisse - Bestimmung der Aktivität der alkalischen Phosphatase - Verfahren mit einem enzymatisch photoaktivierten System (EPAS) (ISO 22160:2007)

Diese Internationale Norm legt ein Verfahren für die Bestimmung der Aktivität der alkalischen Phosphatase in pasteurisierter Vollmilch, Halbfettmilch, Magermilch, Sahne und aromatisierten Milcherzeugnissen mit einem chemilumineszenten (EPAS) Verfahren fest.
Das Verfahren ist für Milch und flüssige Milcherzeugnisse von Kühen, Schafen, Büffeln und Ziegen anwendbar.
Dieses Verfahren ist auch auf Flüssigproben anwendbar, die so verdünnt werden, dass die Aktivität der alkalischen Phosphatase weniger als 7 000 Milliunits je Liter (mU/l) beträgt.
ANMERKUNG   Ein erfolgreicher Ringversuch fand statt, sowohl mit Vollmilch von Kühen, Schafen, Büffeln und Ziegen als auch mit Magermilch von Kühen (Fettgehalt < 0,5 %), Sahne mit 20 % Fettgehalt und Schokoladenmilch mit 2 % Fettgehalt (jeweils Massenanteil).

Lait et boissons à base de lait - Détermination de l'activité de la phosphatase alcaline - Méthode par un système de photoactivation enzymatique (ISO 22160:2007)

L'ISO 22160|FIL 209:2007 spécifie une méthode de détermination de l'activité de la phosphatase alcaline dans les laits pasteurisés entier, demi écrémé, écrémé, la crème et les laits aromatisés, en utilisant une méthode chimiluminescente par photoactivation enzymatique (EPAS).
La présente méthode est applicable au lait de vache, de brebis, de bufflonne et de chèvre ainsi qu'aux boissons à base de lait de ces espèces.
Cette méthode convient également pour tout échantillon liquide, dilué de sorte que l'activité de la phosphatase alcaline diluée présente une teneur inférieure à 7 000 milliunités par litre.
