Foodstuffs - Thermoluminescence detection of irradiated food from which silicate minerals can be isolated
This European Standard specifies a method for the detection of irradiation treatment of food and/or food ingredients by thermoluminescence analysis of contaminating silicate minerals. This method is applicable to those foodstuffs from which a sufficient amount of silicate minerals can be isolated.
The method has been successfully tested in interlaboratory tests with herbs and spices as well as their mixtures [1] to [3], shellfish including shrimps and prawns [4] to [6], both fresh and dehydrated fruits and vegetables [7] to [9], and potatoes [10]. Other studies [11] to [46] demonstrate that the method is applicable to a large variety of foodstuffs.
Lebensmittel - Thermolumineszenzverfahren zum Nachweis von bestrahlten Lebensmitteln, von denen Silikatmineralien isoliert werden können
Diese Europäische Norm legt ein Verfahren fest, das zum Nachweis einer Behandlung von Lebensmitteln mit ionisierenden Strahlen durch Messung der Thermolumineszenz (TL) an mineralischen, silikathaltigen Verunreini-gungen geeignet ist. Das Verfahren ist auf Lebensmittel anwendbar, von denen eine ausreichende Menge an Silikatmineralien isoliert werden kann.
Das Verfahren wurde in Ringversuchen erfolgreich an Kräutern und Gewürzen bzw. Gewürzmischungen [1] bis [3], an Krebs- und Weichtieren einschließlich Garnelen [4] bis [6] sowohl an frischem als auch an getrocknetem Obst und Gemüse [7] bis [9] sowie an Kartoffeln [10] geprüft. Weitere Untersuchungen [11] bis [46] haben gezeigt, dass das Verfahren auf viele verschiedene Lebensmittel angewandt werden kann.
Produits alimentaires - Détection par thermoluminescence d'aliments ionisés dont peuvent être extraits des minéraux silicatés
La présente Norme européenne spécifie une méthode de détection de traitement ionisant appliquée à des produits alimentaires par analyse de la thermoluminescence des minéraux silicatés contaminant l'aliment. Cette méthode s'applique aux produits alimentaires à partir desquels il est possible d'isoler une quantité suffisante de minéraux silicatés.
La méthode a été appliquée avec succès lors d'essais interlaboratoires conduits sur des aromates, des épices, leurs mélanges, [1] à [3], sur des crustacés incluant les crevettes et les langoustes [4] à [6], sur des légumes et des fruits, frais ou déshydratés [7] à [9], et sur des pommes de terre [10]. D'autres études [11] à [46] montrent que cette méthode est applicable à une grande variété d'aliments.
