Investigation Of Benzoic Acid And Sorbic Acid Concentrations In Tomato Paste, Pepper Paste, Ketchup, Mayonnaise, And Barbeque Sauce Samples By Headspace Gas Chromatography-Mass Spectrometry, Orhan Destanoğlu
Turkish Journal of Chemistry
In this study, it was aimed at investigating benzoic acid (BA) and sorbic acid (SoA) concentrations in tomato paste, pepper paste, ketchup, mayonnaise, and barbeque sauce samples by a validated static headspace gas chromatography–mass spectrometry (GC-MS) method. Salicylic acid (SalA) was used as internal standard and the measurements were conducted in the wide linear concentration ranges of BA and SoA which were 2.5–5000 and 12.5–5000, respectively. The limit of detections (LODs) were determined to be 1.5 and 4.5 mg/kg while the limit of quantifications (LOQs) were 2.5 and 12.5 mg/kg for BA and SoA, respectively. The average recovery% values of …
