M/383 - Mycotoxins in food

This European Standard specifies a method for the determination of patulin in fruit juices and fruit-based purée, such as baby food purée, using high performance liquid chromatography with ultra-violet detection (HPLC-UV). Using naturally contaminated and spiked samples this method has been validated for the determination of patulin in apple juice, at levels ranging from 3,0 μg/kg to 15,5 μg/kg, and in fruit-based baby food purée, at levels ranging from 3,4 μg/kg to 17,9 μg/kg. Baby food fruit purée used in this study contained a mixture of the following ingredients which are commercially available on the European market: blueberry; apple; banana; lemon; wheat biscuits; wheat syrup; whole milk; and vegetable oil. A detailed listing, including the fractions, of each product used in this study is given in. Further information on validation, see Clause 9 and Annex B.

This Technical Report gives criteria for single laboratory validated methods of analysis for the determination of mycotoxins. The criteria and topics covered are accuracy, trueness, recovery, precision, measurement uncertainty, selectivity, applicability, linearity, limit of detection, limit of quantification, sensitivity, ruggedness, specificity. This report also contains information on terms and definitions, validation, standardization procedures and interlaboratory studies by international organizations (e.g. AOAC, CEN, ISO, IUPAC, IDF). Confirmatory methods and screening methods are described. The validation criteria specified for mycotoxins in general are given.

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.

This European Standard specifies a method for the determination of zearalenone in maize based baby food, barley flour, maize flour, polenta, wheat flour and cereal based foods for infants and young children by high performance liquid chromatography (HPLC) with immunoaffinity cleanup and fluorescence detection. This method has been validated in two interlaboratory studies. The first study was for the analysis of samples of maize based baby food, barley flour, maize flour, polenta and wheat flour ranging from 10 µg/kg to 335 µg/kg, and the second study was for samples of cereal based foods for infants and young children ranging from 9 µg/kg to 44 µg/kg. Further information on validation, see Clause 9 and Annex B.

This European Standard specifies a method for the determination of aflatoxin B1 in baby food by high performance liquid chromatography (HPLC) with immunoaffinity cleanup and fluorescence detection. This method has been validated in an interlaboratory study via the analysis of both naturally contaminated and spiked samples ranging from 0,07 µg/kg to 0,18 µg/kg. For further information on the validation, see Clause 9 and Annex B.
