Resumo
Mushrooms are excellent nutritional sources since they provide proteins, fibers and mineral, such as K, P, Fe.
They have also been the focus of medical research. In Brazil mushrooms are not consumed in large quantities by
the general population since people know little about the nutritional and medicinal benefits that mushrooms
offer. Hence, this study intends to contribute to a better understanding of the essential element content in edible
mushrooms, which are currently commercialized in São Paulo state. Br Fe, K, Na and Zn concentrations were
determined by Instrumental Neutron Activation Analysis in the following mushroom species: Shitake (Lentinus
edodes), Shimeji (Pleurotus ssp), Paris Champignon (Agaricus bisporus), Hiratake ( Pleurotus ssp) and Eringue
(Pleurotus Eryngü). The mushroom samples were acquired from commercial establishments in the city of São
Paulo and directly from the producers. Essential element contents in mushrooms varied between Br 0.03 to 4.1
mg/kg; Fe 20 to 267 mg/kg; K 1.2 to 5.3 g/kg, Na 10 to 582 mg/kg and Zn 60 to 120 mg/kg. The results
confirm that mushrooms can be considered a good source of K, Fe and Zn. The low Na level is a good
nutritional benefit for the consumer.
