This European Standard specifies a method for the determination of vitamin B2 in food by high performance liquid chromatography (HPLC) and fluorescence detection. This method has been validated in two interlaboratory studies. The first study was for the analysis of samples of milk powder and pig’s liver ranging from 1,45 mg\/100 g to 10,68 mg\/100 g. The second study was for the analysis of samples of tube feeding solution, baby food, powdered milk, meal with fruits, yeast, cereal and chocolate powder ranging from 0,21 mg\/100 g to 87,1 mg\/100 g. Vitamin B2 is the mass fraction of total riboflavin including its phosphorylated derivatives.<\/p>\n

For further information on the validation, see Clause 8 and Annex B.<\/p>\n
