Scope

This Standard specifies the method for the determination of vitamin B6 in foods.
The first method “liquid chromatography - tandem mass spectrometry” is applicable to the
determination of vitamin B6 in foods.
The second method “liquid chromatography - mass spectrometry” is applicable to the
determination of vitamin B6 (pyridoxamine, pyridoxal and pyridoxine) in formulated milk
powder, special dietary foods, ready-to-eat cereals, baked goods and beverages, in which,
vitamin B6 (pyridoxamine, pyridoxal and pyridoxine) is added as a nutritional fortifier.
The third method “high-performance liquid chromatography - fluorescence detection method”
is applicable to the determination of vitamin B6 (pyridoxamine, pyridoxal and pyridoxine) in
formulated milk powder, special dietary foods (except foods for special medical purposes),
ready-to-eat cereals, baked goods and beverages, in which, vitamin B6 (pyridoxamine,
pyridoxal and pyridoxine) is added as a nutritional fortifier.
The fourth method “microbiological method” is applicable to the determination of vitamin B6
in foods.

Summary	This standard specifies the method for the determination of vitamin D in food. The first normal-phase chromatography purification-reverse-phase liquid chromatography method is suitable for the determination of vitamin D and vitamin D in foods added with ergocalciferol or cholecalciferol. The second method, online column switching-reverse-phase liquid chromatography, is suitable for the determination of vitamin D2 and vitamin D in food. The third method liquid chromatography-tandem mass spectrometry is suitable for the determination of vitamin D2 and vitamin D3 in food.
