Abstract

In this study, The aim is to establish the determination method for six preservatives of Benzoic acid, Sorbic acid and four para-hydroxybenzoic acid esters (methyl p-hydroxybenzoate, ethyl p-hydroxybenzoate, propyl p-hydroxybenzoate, butyl p-hydroxybenzoate) in beverage by high performance liquid chromatography(HPLC) simultaneously. After protein precipitation, the sample was diluted by water and separated on a C18 column by a mobile phase consisting of ammonium acetate 0.02M /methanol in gradient elution and detected at the wavelength of 238 nm. The results shows that The recovery of these six preservatives in the method was 93.2% to 103.8% with correlation coefficients from 0.9996 to 0.9999. The detection limit of these six preservatives was between 0.01g/kg and 0.03g/kg. The method developed is sensitive, simple, accurate and suitable for the determination of six preservatives in beverage.
