Rapid In Situ Esterification Method for the Determination of Benzoic Acid in Dairy Milk by GC-FID

Investigation of benzoic acid and sorbic acid in snack foods in Jilin province, China

“…However, exceeding the permitted levels may cause some adverse reactions, including metabolic acidosis, convulsions, asthma, and allergic reactions. [6,7] There are many analytical techniques for detecting benzoic acid and sorbic acid in foods, such as biosensor [8][9][10] ,capillary electrophoresis [11,12] , gas chromatography [13][14][15] , high-performance liquid chromatography [16][17][18] . Currently, the most common method used in the food industry is high-performance liquid chromatography (HPLC).…”

A validated stability-indicating HPLC-DAD method for simultaneous determination of econazole nitrate, triamcinolone acetonide, benzoic acid and butylated hydroxyanisole in cream dosage form

“…The reported methods involved the use of HPLC, [3][4][5][6] liquid chromatography-tandem mass spectrometry (LC/ MS/MS), 7,8 capillary zone electrophoresis, 9 GC-MS, 10 HPTLC, 11,12 stripping voltammetry 13 and UV derivative spectrophotometry. 12 On the other hand, quantication of BA and/or BHA in pharmaceutical preparations or food products was carried out using various techniques such as HPLC-UV detection, 14 HPLC-DAD, 15 HPLC-chemiluminescence detection, 16 ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS), 17 UPLC-DAD, 18 capillary electrophoresis-amperometric detection, 19 capillary electrophoresis-electrospray ionization mass spectrometry, 20 micellar electrokinetic capillary chromatography, 21 TLC-densitometric detection, 22 gas chromatography-ame ionization detection (GC-FID), 23,24 GC-MS 25,26 and voltammetry. 27,28 The simultaneous determination of EN and TA was described in a couple of articles.…”
