    Abstract:
    OBJECTIVE: To establish a qualitative system for the identification of benzoic acid, sorbic acid and dehydroacetic acid residues in alcoholic drinks and beverages by ultra-fast liquid chromatography coupled with electrospray ionization tandem mass spectrometry (UFLC/ESI-MS/MS). METHODS: After the sample was extracted, the separation was performed by UFLC and the cracking was used by the optimized ESI-MS/ MS conditions. Confirmatory detection was carried out by the principle of three qualitative ions and retention time using an UFLC-MS/MS in the negative electrospray ionization mode. RESULTS: The MS/MS fragment ions were reliable and steady under the suitable conditions, the cracking ways to the parent ions and fragment ions were clear. Qualitative ion pairs were m/z 121-->77 and m/z 121-->59 for benzoic acid, m/z 111-->67 and m/z 111-->41 for sorbic acid, m/z 167-->83 and m/z 167-->123 for dehydroacetic acid. The limits of quantitation (LOQs) were 0.02, 0.05 and 0.02 mg/L for benzoic acid, sorbic acid and dehydroacetic acid, respectively. CONCLUSION: The established method was rapid, accurate and sensitive, it is suitable for confirmation for benzoic acid, sorbic acid and dehydroacetic acid residues in alcoholic drinks and beverages.
