Foodstuffs. Determination of vitamin B1 by high performance liquid chromatography not-eligible • A more effective and1 Scope This European Standard specifies a method for the determination of vitamin B1 in food by high performance liquid chromatography (HPLC) with enzymatic treatment and pre or post column derivatization. This method has been validated in two interlaboratory studies. The first study was for the analysis of samples of whole meal flour, milk powder spray dried milk, freeze dried mixed vegetables and freeze dried pig's liver ranging from 0,295 mg 100 g
