Abstract: Due to presented in literature potential health benefits of shiitake Lentinula edodes (Berk.) Pegl. and oyster mushroom Pleurotus ostreatus (Jacq.: Fr.) Kumm., chemical composition as well as Fe, Cu and Zn ions sorption (in conditions related to human digestive tract) by dried shiitake and oyster were investigated. Both dried mushrooms had the high content of dietary fiber, Fe, Cu, Mg, K but low of fat, Na and Ca. Relatively low sorption of micronutrients was found in pH = 1.8, while the high sorption of Cu and Fe was observed in pH = 8.7. Dried mushrooms satisfied the maximum permissible level standards concerning toxic metals. The results of the research suggest that dried shiitake and oyster mushrooms can be used as additives in food products.
