“…Recent literature review shows that gas chromatography coupled to single or tandem mass spectrometric approaches (GC-MS, GC-MS/MS) served as an efficient tool for the determination of various organic compounds in food samples (Table 2). GC was used to quantify: 200 multiclass pesticides in fruits [67]; 14 lipophilic pesticides in raw propolis [68]; 5 organophosphorus pesticides (OPPs) in fruit juice and water [69], endocrine disrupting chemicals (EDCs) i.e., alkylphenols; 4 phenylphenols, bisphenol A; 7 parabens; 11 OPPs and triclosan in different cereal-based foodstuffs [70]; 4 isomers of hexachlorocyclohexane; 6 pyrethroid pesticides i.e., bifenthrin, fenpropathrin, cyhalothrin, cyfluthrin, cypermethrin, deltamethrin in milk [71]; 133 multiclass pesticides in pericarpium citri reticulatae (chenpi) [72]; 5 NSAIDs i.e., ibuprofen, paracetamol, diclofenac, naproxen, ketoprofen; 3 natural estrogens i.e., estrone, 17β-estradiol, estriol in Mussels Mytilus edulis trossulus [73], glyoxal and methylglyoxal in different alcoholic beverage and fermented foods [74], essential fatty acids in cereals and green vegetables [75], and fatty acids in grilled pork [76]. Crude fat, total saturated acids, and total trans fatty acids in home meal replacements, and restaurant foods were analyzed using GC-FID (gas chromatography-flame ionization detector).…”
