Análise da presença de metais em cervejas artesanais e tradicionais comercializadas no Paraná

Abstract

This work, he talks a little about beer, which is the most consumed alcoholic beverage on the planet, originating from a natural fermentation when discovered, but nowadays industrialized and with large-scale production, where possible contamination from the soil, water or even the industrialization process. Samples of 10 different types of beer were purchased at a supermarket in the city of Goioerê-Paraná and submitted to analysis by flame atomic absorption spectroscopy (FAAS) to determine the metal content. For FAAS analysis, beer samples were prepared using deionized water as solvent. For comparative standards, the samples were digested by incineration in a muffle furnace for total availability of metals in solution. The solutions obtained in the two steps were analyzed for lead, copper, iron and the metallic mineral magnesium. Results were negative for lead and copper in all conditions, while iron and magnesium levels varied depending on the beer samples used.
