No information added.
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 (commercially available on the European market) used in this study contained the following ingredients: 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.
