Polycyclic Aromatic Hydrocarbons (PAHs) Sample Preparation and Analysis in Beverages: A Review

Abstract The monitoring of food contaminants is interests to both regulatory bodies and the consumers. This literature review covers polycyclic aromatic hydrocarbons (PAHs) with regard their background, sources exposures, occurrence in environment as well health hazards. Furthermore, analytical methods focusing on analysis PAHs tea, coffee, milk, alcoholic samples for last 16 years are presented. Numerous experimental have been developed aiming obtain better limits detections (LODs) percent recoveries reduce solvent consumption laborious work. These include information such selected analyzed, matrix PAHs, extraction, cleanup procedure, LOD, quantitation (LOQ), recovery. For samples, a majority research papers focused US Environmental Protection Agency while PAH4, PAH8, methylated were also interests. Extraction range from classic Soxhlet extraction liquid–liquid newer QuEChERS, dispersive solid-phase microextraction, magnetic extraction. involved mainly use column chromatography SPE filled either silica or Florisil adsorbents. Gas liquid coupled mass spectrometry fluorescence detectors main instruments used. A combined used able achieve LODs ranges 0.01–5 ug/kg 70–110%, respectively, samples.
