Twenty-five samples of saffron (11) pepper (9) and herbs seasonings and spice blends (5) from Asia South America Africa and Europe have been analyzed by means of the EN 1788 protocol The thermo-luminescence (TL) emission of minerals isolated from the foodstuffs allows us to differentiate between irradiated (1) and non-irradiated (24) samples According to the X-ray diffraction and environmental scanning microscope the mineralogical composition adhered to the samples is mainly made up of different amounts of quartz calcite mica gypsum K and Na-rich feldspars kaolinite clinochlore and (only in mixtures) halite All of them are sensitive to ionizing radiation exhibit enough TL intensity have high stability of the U signal during the storage of the material and are thermally and chemically stable The EN 1788 European Standard
