Foodstuffs - Determination of deoxynivalenol in cereals, cereal products and cereal based foods for infants and young children - HPLC method with immunoaffinity column cleanup and UV detection
This European Standard specifies a method for the determination of deoxynivalenol (DON) in cereals (grain and flour), cereal based foods and cereal based foods for infants and young children by high performance liquid chromatography (HPLC) with immunoaffinity cleanup and UV detection. This method has been validated in three interlaboratory studies. The first study was for the analysis of samples of wheat, rice flour, oat flour, maize, polenta, and wheat based breakfast cereal ranging from 85,4 µg/kg to 1 768 µg/kg, the second study was for wheat and maize ranging from 165 µg/kg to 4 700 µg/kg and the third study was for cereal based foods for infants and young children ranging from 58 µg/kg to 452 µg/kg.
For further information on the validation, see Clause 9 and Annex B.

Lebensmittel - Bestimmung von Deoxynivalenol in Getreide, Getreideerzeugnissen und Säuglings- und Kleinkindernahrung auf Getreidebasis - HPLC-Verfahren mit Reinigung an einer Immunoaffinitätssäule und UV-Detektion
Diese Europäische Norm legt ein Verfahren zur Bestimmung von Deoxynivalenol (DON) in Getreide (Korn und Mehl), Getreideerzeugnissen und Säuglings- und Kleinkindernahrung auf Getreidebasis durch Hochleistungs¬flüssigchromatographie (HPLC) mit Reinigung an einer Immunoaffinitätssäule und UV Detektion fest. Dieses Verfahren wurde in drei Ringversuchen getestet. Der erste Ringversuch wurde an Weizen, Reismehl, Hafermehl, Mais, Maisgrieß und Frühstückscerealien auf Weizenbasis mit 85,4 µg/kg bis 1 768 µg/kg durchgeführt. Der zweite Ringversuch wurde an Weizen und Mais mit 165 µg/kg bis 4 700 µg/kg und der dritte Ringversuch wurde mit Säuglings- und Kleinkindernahrung auf Getreidebasis mit 58 µg/kg bis 452 µg/kg durchgeführt.

Denrées alimentaires - Dosage du déoxynivalénol dans les céréales, les produits céréaliers, et céréales pour déjeuner en alimentation infantile - Méthode par CLHP avec purification sur colonne d'immunoaffinité et détection UV
La présente Norme européenne spécifie une méthode de dosage du déoxynivalénol (DON) dans les céréales (grains et farines) et les produits céréaliers et les aliments à base de céréales pour nourrissons et jeunes enfants par chromatographie liquide haute performance (CLHP) avec purification sur colonne d'immunoaffinité et détection UV.

Ta evropski standard določa metodo za določevanje deoksinvalenola (DON) v žitih (žita in moka), hrani na osnovi žit in hrani na osnovi žit za dojenčke in majhne otroke s tekočinsko kromatografijo visoke ločljivosti (HPLC) z imunoafinitetnim čiščenjem in ultravijolično (UV) detekcijo. Ta metoda je bila potrjena v treh medlaboratorijskih študijah. Prva študija je bila za analizo vzorca žit, riževe moke, ovsene moke, koruze, polente in žitaric za zajtrk v razponu od 85,4 μg/kg do 1768 μg/kg, druga študija je bila za žito in koruzo v razponu od 165 μg/kg do 4700 μg/kg in tretja študija je bila za hrano na osnovi žit za dojenčke in majhne otroke v razponu od 58 μg/kg do 452 μg/kg.

Dilute 200 µl of stock solution 2 (4.21) to 2,0 ml with acetonitrile (4.11) to form a solution with a concentration of approximately 25 µg/ml. To determine the exact mass concentration, record the absorption curve between a wavelength of 200 nm to 270 nm, e.g. in 5 nm steps; in the spectrometer (5.16) against acetonitrile as reference. Identify the wavelength for maximum absorption and calculate the mass concentration of deoxynivalenol, DON, in micrograms per millilitre using Equation (1):
