Foodstuffs - Detection of food allergens by immunological methods - Part 1: General considerations

This European Standard provides the overall framework of qualitative and quantitative methods for the determination of allergens and allergenic ingredients in foodstuffs using antibody-based methods. This European Standard specifies general guidelines and performance criteria for antibody-based methods for the detection and quantification of proteins that serve as a marker for the presence of allergy provoking foods or food ingredients. Other methods than those described may also detect and identify the proteins. Guidelines, minimum requirements and performance criteria laid down in the standard are intended to ensure that comparable and reproducible results are obtained in different laboratories. This European Standard has been established for food matrices

Lebensmittel - Nachweis von Lebensmittelallergenen mit immunologischen Verfahren - Teil 1: Allgemeine Betrachtungen

Diese Europäische Norm liefert den Gesamtrahmen für die qualitativen und quantitativen Verfahren zur
Bestimmung von Allergenen und allergenen Zutaten von Lebensmitteln unter Anwendung von auf Antikörpern
basierenden Verfahren. Diese Europäische Norm legt die allgemeinen Leitlinien und Leistungskriterien für auf
Antikörpern basierende Verfahren zum Nachweis und zur quantitativen Bestimmung von Proteinen fest, die
als Marker für das Vorliegen von allergieauslösenden Lebensmitteln oder Lebensmittelzutaten dienen. Auch
mit anderen als den beschriebenen Verfahren können die Proteine nachgewiesen und identifiziert werden. Die
in dieser Norm angeführten Leitlinien, Mindestanforderungen und Leistungskriterien sind dafür vorgesehen,
sicherzustellen, dass in verschiedenen Laboratorien vergleichbare und reproduzierbare Ergebnisse erhalten
werden. Diese Norm wurde für Lebensmittelmatrices erarbeitet.

Produits alimentaires - Détection des allergènes alimentaires par des méthodes d'analyse immunologiques - Partie 1: Considérations générales

La présente Norme européenne fournit un cadre général relatif aux méthodes qualitatives et quantitatives utilisées pour déterminer les allergènes et ingrédients allergéniques contenus dans les produits alimentaires, en appliquant des méthodes basées sur des anticorps. La présente Norme Européenne énonce des lignes directrices et des critères de performances généraux relatifs à des méthodes basées sur des anticorps, en vue de la détection et de la quantification de protéines qui servent de marqueurs indiquant la présence d’aliments ou d’ingrédients alimentaires à l’origine d’allergies. Il existe d’autres méthodes que celles décrites, susceptibles de détecter et d’identifier les protéines. Les lignes directrices, les exigences minimales et les critères de performances établis dans la présente norme sont destinés à assurer que des laboratoires différents obtiendront des résultats comparables et reproductibles. La présente Norme européenne a été élaborée pour les matrices alimentaires.

EN 15633-1:2009 (E) 4 Introduction A specific protein or group of proteins or peptides deriving from these proteins can serve as a marker for the presence of food or food ingredients provoking allergic reactions. This European Standard describes the procedure to qualitatively detect and/or quantitate a protein as a marker for potentially allergenic ingredients or constituents by analysing the protein extracted from the sample under study. Appropriate procedures for extraction of the protein are included in each method. The main focus of this European Standard will be on antibody based methods.
