Coffee and tea are the most popular beverages and consumed by millions of people all over the world, several times a day. Coffee is now the most important food commodity worldwide, ranking second among all commodities after crude oil. Roasting is an essential step in the production of coffee, as it enables the development of colour, aroma and flavour, which are crucial for coffee quality. However, roasting may also lead to the formation of undesirable compounds, such as polycyclic aromatic hydrocarbons . Tea is the second most widely consumed beverage in the world next to coffee, and the global tea out-put has significantly increased over the last decade. While tea consumption has many health benefits , some studies have also reported that tea leaves may contain some organic contaminants that might be harmful to human health. In particular, a wide variety of polycyclic aromatic hydrocarbons have been detected on tea leaves. However, due to the extremely low concentrations of PAHs in coffee and tea, as well as the complex matrices of the coffee and tea samples, sample preparation is required prior to instrumental analysis to obtain sensitive and accurate results.
