Abstract:
One of the most used methods for food preservation is gamma-irradiation. The effects of this method on five species of dried mushroom, currently used in gastronomy: yellow morel - Morchella esculenta, (L.) Pers. (Phylium Ascomycota), button mushroom - Agaricus bisporus (J.E.Lange), Agaricus haemorrhoidarius Fr., golden chantarelle - Cantharellus cibarius Fr., as well as oyster mushroom - Pleurotus ostreatus (Jacq. ex Fr.) (Phyllium Basidiomycota) is studied by electron paramagnetic resonance (EPR) spectroscopy. EPR spectra induced by gamma-irradiation and their stability are
presented and the suitability of EPR detection of irradiated mushrooms is discussed.
