Because fruiting bodies of edible mushrooms accumulate elements very effectively, in this study for the first time we aimed at determining the degree of the release of zinc(II) ions to artificial digestive juices imitating the human gastrointestinal tract from freeze-dried popular edible mushroom fruiting bodies, such as Agaricus bisporus, Boletus badius and Cantharellus cibarius. For the analysis, anodic stripping voltammetry method was used. The amount of zinc released to artificial saliva within 1 minute ranged from 0.03 to 1.14 mg/100 g d.w. In gastric juice, the amounts were higher and ranged from 0.75 to 2.07 mg/100 g d.w. depending on the incubation time. After incubation of the freeze-dried edible mushroom fruiting bodies for 1 minute in artificial saliva, 15 in artificial gastric juice and then 150 minutes in artificial intestinal juice, it was found that the concentration of the released zinc in artificial intestinal juice was the highest and amounted to 6.44 mg/100 g d.w. The total average amount of zinc released from Boletus badius was the highest and this was estimated at 4.13 mg/100 g d.w. For the remaining two investigated species of A. bisporus and C. cibarius, the total amounts of zinc released into artificial digestive juices were only slightly lower and were estimated at 2.23 and 3.29 mg/100 g d.w. on average, respectively. It was demonstrated for the first time that mushrooms release zinc to artificial digestive juices imitating conditions in the human digestive tract and are a good source of this element.
