B. edulis dried and sliced samples were obtained in a local store (Bragança, Northeast of Portugal), in May 2013, packed in hermetic sealed polyethylene bags and labeled as “Porcini mushrooms”, with the indication of species “B. edulis” below the commercial designation. Subsequently, the content of 10 packages (20 g each) was mixed and four individual samples were separated: control (non-irradiated, 0 kGy); sample 1 (2 kGy); sample 2 (6 kGy) and sample 3 (10 kGy).
