DESCRIPTION
BS EN 14164:2014
This standard BS EN 14164:2014 Foodstuffs. Determination of vitamin B6 by high performance chromatography is classified in these ICS categories:
- 67.050 General methods of tests and analysis for food products
This European Standard specifies a method for the determination of vitamin B6 in foodstuffs by high performance liquid chromatography (HPLC). Vitamin B6 is the mass fraction of the sum of pyridoxine, pyridoxal, pyridoxamine including their phosphorylated derivatives determined as pyridoxine. The β-glycosylated forms are not taken into account. These can be determined with the method given in EN 14663 [1] by which the different vitamins of vitamin B6 (pyridoxal, pyridoxamine and pyridoxine) are separated and individually quantified. A third European Standard, EN 14166 [2], determines the total vitamin B6 by microbiological assay.
