DIN EN 14122-2014食品.液相色谱法测定维生素B1的含量;德文版本EN 14122-2014

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 to 0,807 mg/100 g. The second study was for the analysis of samples of tube feeding solution, baby food with vegetables, powdered milk, meal with fruits, yeast, cereal, chocolate powder and food supplement ranging from 0,11 mg/100 g to 486 mg/100 g. Vitamin B1 is the mass fraction of total thiamin including its phosphorylated derivatives.

DIN EN 14152-2014食品.液相色谱法测定维生素B2;德文版本EN 14152-2014

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.
