<jats:p> In this work, we present a review of the research developed by the PIXE Group of Ion Implantation Laboratory (Porto Alegre, Brazil) for the elemental characterization of food and beverages in general. Samples of coffee, wine, wine stoppers, mate tea leaves (Ilex paraguariensis) and tuna fish were analyzed using Particle-Induced X-ray Emission (PIXE) in order to determine their elemental compositions. Elements ranging from atomic number 11 to 82 were detected, and it was possible to observe differences in the elemental composition among different brands of wine and tuna fish. Moreover, the influence of water volume on the leaching of elements in the mate tea as well as the inhomogeneity of coffee beans and wine stoppers were studied. </jats:p>
