Determination of Elemental Composition of Some Wild Growing Edible Mushrooms
Ali Keleş
Abstract
The aim of this study was to determine and elaborate the mineral contents and the some highly toxic elements of wild grown-edible mushrooms. The potassium (K), magnesium (Mg), calcium (Ca), manganese (Mn), iron (Fe), zinc (Zn), copper (Cu), nickel (Ni), cadmium (Cd) and lead (Pb) contents of twenty edible mushrooms, collected from Gümüşhane province, Turkey, were analyzed. The studied mushrooms varied widely in their content of both essential and toxic deleterious elements. The minimum and maximum mineral contents of mushrooms were determined as mg/kg dw for K (4170-15747), Mg (295-2095), Ca (100-2778), Mn (3.82-170.25), Fe (50.25-1121.53), Zn (22.99-91.76), Cu (5.89-135.35), Ni (1.05-6.07), Cd (0.06-7.29) and Pb (0.02-30.46) were determined. The potassium content was found to be higher than those of the other minerals in all the mushrooms. Lead and cadmium were present but at concentrations that are not hazardous to human health except for Armillaria ostoyae. The K, Mg, Ca, Mn, Fe, and Cu concentrations were determined to be high in Agrocybe dura. Mushrooms have become increasingly attractive as functional foods for their potential beneficial effects on human health. Also, mushrooms are important in the ecosystem because they are able to biodegrade the substrate, to collect heavy metal.
