Rapid Determination of Benzoic Acid and Sorbic Acid Content in Mixed Wine

Xiaohua Li

Abstract

A method for rapid determination of benzoic acid and sorbic acid content in mixed wine had been developed by use of HPLC.The optimum chromatographic conditions were summed up as follows: the column temperature was at 25 ℃,the volume ratio of methanol and 0.02 mol/L NH4Ac was 20:80,and the speed of mobile phase was 1 mL/min.Such method was suitable for rapid determination of large quantity of samples due to its simplicity,reliability and high precision.
