Mineral composition of traditional and organic-cultivated mushroom Lentinula edodes in Europe and Asia – Similar or different?

The goal of this study was to compare the mineral composition of Lentinula edodes (Berk.) Pegler fruit bodies available on the Polish and German markets in 2019 and grown in 5 countries in Europe and Asia. Organically-cultivated fruit bodies from Europe contained a higher amount of K, Mg and Na but also a lower level of rare earth elements than traditionally cultivated L. edodes from Asia. The highest mean contents of K, Mg and Na were determined in mushrooms from Polish organic food stores (21,700; 1,330 and 144 mg kg−1, respectively). The highest mean content of Al, As, Au, Ba, Cs, Li, Os, Pb, Pt, Sr, Th, Ti and V was determined in dried Vietnamese L. edodes (91.2, 7.09, 0.168, 5.23, 35.0, 0.400, 0.189, 1.07, 1.77, 1.86, 0.172, 4.58 and 0.251 mg kg−1, respectively) with no significant differences in Cd and Hg content between all the studied groups of mushrooms. The highest content of all elements was determined in traditionally cultivated L. edodes fruit bodies from Vietnam and organically-cultivated mushrooms from Poland. The results revealed similarities in terms of the total content of elements, but a different mineral composition, thus providing important information for potential consumers of this mushroom species. [Display omitted] • Traditionally (TC) and organic-cultivated (OC) L. edodes were studied. • Higher amount of nonessential and toxic metals in TC than OC was determined. • TC fruit bodies contained a lower amount of rare earth elements than OC. • Mineral composition of TC market L. edodes should be randomly controlled. • Intake of studied mushrooms was not the cause of potential health risk.
