Abstract
Roasting may lead to the formation of undesired compounds, such as polycyclic aromatic hydrocarbons (PAHs). In this study, green coffee beans were roasted under controlled conditions and the formation of PAHs during the roasting process was monitored. Roasting was performed in a hot air roaster, with an inlet air temperature varying from 150 to 250°C for 5, 10, and 20 min. The PAH content of the roasted coffee was then evaluated by HPLC-FLD. The levels of total PAHs in Arabica (Colombia, Brazil) and Robusta (India) coffee samples were 1.26-215.07, 1.85-178.14, and 0.18-2.61 μg/kg, respectively.
