Analysis and Investigation of Benzoic Acid in Food
Abstract: In the paper, based on the situations nowadays, with the common preservative-benzoic acid as the inspection object and ginseng extract/ginseng beard as raw material, the content of benzoic was detected rapidly by means of solid phase extraction-HPLC. The optimal chromatographical conditions to detect benzoic in ginseng extract and ginseng beard were confirmed. The analytical method of solid phase extraction-HPLC to detect benzoic acid in ginseng extract and ginseng beard was investigated. The linear relationship was satisfying with the correlation coefficient ≥ 0.9994, and the detection limit of this method was 0.039 µg/mL, which meets the requirement of the inspection of benzoic acid content in ginseng extract and ginseng beard.
