Dissertation note: Thesis (Ph.D.) - Cairo University - Faculty of Science - Department of Biophysics Summary: Ionizing radiation (IR) has been used extensively as a physical means for preserving food by eliminating pathogenic bacteria and thereby improving safety. In terms of food safety and for strengthening worldwide trade of irradiated foods, the presence of a trustworthy method for identification of irradiated foodstuff and for ensuring that food irradiation is performed by proper permissible doses is currently the focus of attention. Thus, developing reliable means for detecting food preserved by irradiation is a crucially important issue for public health. The present work introduces Fourier transform infrared (FTIR) spectroscopy technique for fast and sensitive detection of irradiated liver as an animal-derived foodstuff. This study presents a unique application of FTIR spectroscopy measurements on DNA, extracted from irradiated livers in order to detect possible structural modifications in DNA induced by IR
