Samples of toasted guaraná seeds with husk from Maués (Amazônia) and ten samples of different brands of guaraná powder produced in different parts of Brazil were analysed in this work, aiming to identify and quantify 16 PAHs. The samples were analysed by high-performance liquid chromatography equipped with fluorescence and UV-Vis detectors. Naphthalene was identified and quantified in the guaraná samples (0.13 and 0.78μgkg(-1)) and both naphthalene and phenanthrene were found in two commercial guaraná powder samples (0.36-1.54 and 0.03-0.06μgkg(-1), respectively). Considering that the average daily intake of guaraná powder is equivalent to 10g, it can be seen that guaraná powder contains less PAHs than the limit established in European legislation for other kinds of food (CE 835/2011), that is, around 0.20μgkg(-1) of PAHs.
