|Title:||Determination Of Polycyclic Aromatic Hydrocarbons In Cachaça By Hplc With Fluorescence Detection|
|Abstract:||Cachaça is a distilled alcoholic beverage obtained from sugar cane fermentation. In this study, 25 brands of cachaça commercially available in Brazil were analysed for the presence of 5 PAHs (benz[a]anthracene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[a]pyrene and dibenz[a,h]anthracene). The methodology involved liquid-liquid extraction with cyclohexane and dimethyilformamide-water (9:1, v/v), clean up on silica gel column and determination by high performance liquid chromatography using fluorescence detection. PAHs peak identity was confirmed by gas chromatography-mass spectrometry (GC-MS). Variable levels of summed PAHs were detected in the analysed samples, ranging from not detected to 1.94 μg/L. The results confirm the presence of PAHs in cachaça and suggest that contaminated sugar cane may be the source of PAHs in sugar cane spirits. © 2006 Elsevier Ltd. All rights reserved.|
