Foodstuffs - Determination of vitamin B6 by high performance chromatography

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.

Lebensmittel - Bestimmung von Vitamin B6 mit Hochleistungs-Flüssigchromatographie

Diese Europäische Norm legt ein Verfahren zur Bestimmung von Vitamin B6 in Lebensmitteln mit Hochleistungs Flüssigchromatographie (HPLC) fest. Vitamin B6 ist der Massenanteil der Gesamtmenge an Pyridoxin (PN), Pyridoxal (PL) und Pyridoxamin (PM), einschließlich ihrer phosphorylierten Derivate, die als Pyridoxin bestimmt werden. Die  glycosylierten Formen werden nicht berücksichtigt. Diese können mit dem in EN 14663 [1] festgelegten Verfahren bestimmt werden, bei dem die verschiedenen Vitamere von Vitamin B6 (Pyridoxin, Pyridoxal und Pyridoxamin) getrennt und individuell bestimmt werden. Eine dritte Europäische Norm (EN 14166) [2] bestimmt den Gesamtgehalt an Vitamin B6 mikrobiologisch.

Produits alimentaires - Détermination de la teneur en vitamine B6 par chromatographie liquide haute performance

La présente Norme européenne spécifie une méthode de dosage de la vitamine B6 présente dans les produits alimentaires par chromatographie liquide haute performance (CLHP). La vitamine B6 est la fraction massique de la somme de la pyridoxine, du pyridoxal et de la pyridoxamine, y compris leurs dérivés phosphorylés quantifiés sous la forme pyridoxine. Les formes β-glycosylées ne sont pas prises en compte. Elles peuvent être dosées selon la méthode indiquée dans l'EN 14663 [1], qui permet de séparer et de quantifier individuellement les différentes formes de vitamine B6 (pyridoxal, pyridoxamine et pyridoxine). Une troisième Norme européenne, l’EN 14166 [2], traite du dosage de la vitamine B6 totale par essai microbiologique.

Živila - Določevanje vitamina B6 s tekočinsko kromatografijo visoke ločljivosti

Standard EN 14164 navaja metodo za določanje vitamina B6 v živilih s tekočinsko kromatografijo visoke ločljivosti (HPLC). Vitamin B6 je masni delež vsote piridoksina, piridoksala in piridoksamina, vključno z njihovimi fosforiliranimi derivati, ki so določeni kot piridoksin. β-glikozilirane oblike se ne upoštevajo. Te je mogoče določiti z metodo iz standarda EN 14663, pri kateri so različni vitamini vitamina B6 (piridoksal, piridoksamin in piridoksin) ločeni in posamezno izmerjeni. Tretji evropski standard, EN 14166, določa skupno vrednost vitamina B6 z mikrobiološkim preskusom.
