Determination of ascorbic acid and its salts in food additives and fodder additives

INTRODUCTION

The method is used for the determination of the mass fraction of ascorbic acid and its salts in food additives and fodder additives (feed additives).
The present method does not allow the determination of ascorbic acid in premixes.
For the determination of acetic, benzoic, butyric, citric, formic, fumaric, lactic, malic, oxalic, propionic, sorbic, and succinic acids in fodder additives and butyric acid in silage and haylage use the method М 04-74-2012 (Lumex Instruments set, order No 0300001897).

MEASURING METHOD

The measurement method is based on capillary zone electrophoresis with direct UV detection at the wavelength of 254 nm.
