Chemical composition and trace element analysis of tricholoma equestre collected from Batak mountain in Bulgaria

Tricholoma equestre was rich in carbohydrates (88.03g 100 -1 g -1 dw), followed by proteins (5.65 g 100 -1 g -1 dw), ash (4.57g 100 -1 g -1 dw) and fat (1.75 g 100 -1 g -1 dw).Moisture (88.31%) and Energy (390.49 kcal 100 -1 g -1 dw) were also calculated.The concentrations of trace elements : Fe (12.85 ± 0.68 mg kg -1 ), Zn (8.63 ± 0.19 mg kg -1 ), Cu (1.16 ± 0.14 mg kg -1 ) and Mn (0.85 ± 0.13 mg kg -1 ), were assayed.Trace elements content of samples indicated that the Batak mountain was an ecologically pure region in Bulgaria, and therefore the mushrooms collected from this location could be consumed without any risk for human health.According to this study, the edible wild mushroom Tricholoma equestre could be used in human nutrition due to its good properties.
