This document specifies a method for the determination of benzoic acid and sorbic acid in animal feeding
stuffs by high-performance liquid chromatography method with ultraviolet detection (HPLC-UV).
The method is intended to be used for the determination of benzoic acid and sorbic acid as active
substances in feed additives, premixtures, feed materials and compound feed and for benzoic acid in
water. This method determines the total extractable concentration of these organic acids and their salts.
It is advisable that the working range of the method is determined for each organic acid by the user of
this standard. The lower limit of the working range depends on the matrix and the interferences
encountered. It is advisable that a working range between 5 mg/l and 100 mg/l is accessible.
The method was successfully tested in an inter-laboratory study in concentrations between 0,02 % up to
9,0 %.
