Effect of solvents on extraction of polycyclic aromatic hydrocarbons from Coffee, Chicken and Kitchen exhaust depositions
Journal Title: International Journal of Engineering and Science Invention - Year 2017, Vol 6, Issue 10
Abstract
Polycyclic aromatic hydrocarbons are carcinogenic compounds which are formed and accumulated in different food products at pre- and post-harvest stages. Extraction is an important step performed prior to PAHs determination and is governed by various factors. Type of solvent used for extraction is one such factor affecting the quantification and profiling of PAHs based on its interaction with food matrix. The present study focused on selection of solvent for the higher extraction efficiency of PAHs from matrices such as chicken, coffee and kitchen exhaust depositions. The different solvents such as cyclohexane, hexane, toluene, acetonitrile and DCM:Hexane were targeted. The highest concentration of total PAHs extracted from food matrix varied greatly with solvent used. Highest PAHs concentration (36.30 mg/kg) was obtained in kitchen exhaust depositions followed by coffee (28.96mg/kg) and chicken (19.39mg/kg) when the solvents of extraction were in cyclohexane, acetonitrile and toluene, respectively.
