Abstract
Collaborative studies were conducted to evaluate the effectiveness of analytical methods based on immunoaffinity column clean-up prior to high performance liquid chromatography (HPLC) for the determination of aflatoxin B1 and total aflatoxins at European regulatory limits in various food products (4 ng/g total aflatoxins, 2 ng/g aflatoxin B1), baby food (0.1 ng/g aflatoxin B1 in discussion) and feeding stuff (1 ng/g aflatoxin B1 in discussion).
The methods showed acceptable within-laboratory and between-laboratory precision for all matrices at these low levels for the determination of both, total aflatoxins and aflatoxin B1.
Zusammenfassung
Gemeinsame Arbeiten konnten durchgeführt werden, um die Wirksamkeit analytischer Methoden auf der Basis von Affinitätssäulen zu evaluieren. Hier wurde vor allem die Hochdruckflüssigkeitschromatographie (HPLC) zur Bestimmung von Aflatoxin B1 und Gesamtaflatoxinen nach den europäischen Regelwerten (Nahrungsmittel: 4 ng/g Gesamtaflatoxine und 2 ng/g Aflatoxin B1, Babynahrung: 0,1 ng/g Aflatoxin B1 als Richtwert in der Diskussion, Futtermittel: 1 ng/g Aflatoxin B1 in der Diskussion) für verschiedene Produkte überprüft. Die Methoden mit allen angewendeten Matrices lieferten akzeptierbare Ergebnisse sowohl bei Vergleichen innerhalb eines Labors als auch bei solchen aus verschiedenen Laboratorien.
