Sažetak

Application of ionising radiation in the preservation of foodstuffs on the world food market, irradiation treatment regulations and demands of consumers for clear declaration of irradiated foodstuffs have emphasis the need for the development of analytical methods for the detection of foodstuffs preserved by ionising radiation. One of the most accurate methods for the identification of irradiated foodstuffs is EPR spectroscopy. EPR spectroscopy is a physical method for detecting unpaired electrons, especially free radicals induced by ionising radiation. This paper describes the use of EPR spectroscopy as identificationtest for the radicals induced in Norway lobster during the preservation by ionising radiation and the application of EPR spectroscopy in testing of prescribed dose.
