[en] This study investigated the effect of gamma irradiation on pathogens, quality, and functional properties of shell eggs. Using intact, fresh while and brown shell eggs, inoculated with 10⁹ colony-forming units (cfu) of S enteritidis and S, typhimurium. The effect of gamma-irradiation at doses 2,4 and 6 kGy of gamma irradiation on bacteriologic and population and physical characteristics (Haugh units and yolk color), chemical composition (moisture, crude protein, crude fat and ash), the rheological changes (viscosity), pH and protean solubility of the eggs were determinate d. Results showed that 2 kGy, the number of S, enteritidis and eggs internal quality as freshness as measured by albumen height and the number of hugh units, and yolk color index were all significantly reduced with increasing irradiation doses. On significant change was found after irradiation in egg white or yolk in the chemical composition (moisture, crude protein, crude fat and ash). After irradiation, the foaming ability and foam capacity of egg white were increasing radiation doses> The viscosity of egg white and yolk decreased with increasing doses of irradiation. The pH of the egg white and yolk increasing doses of radiation dose. The protein salability decreased significantly in egg white and yolk with increasing radiation dose. These Results Suggest that gamma irradiation reduce the freshness of shell eggs and improving important functional properties such as to foaming ability and foaming capacity. Gamma irradiation can also be applied to the egg breaking process sine irradiation reduces the viscosity of egg white and yolk, which can allow egg whites and yolks to be separated with greater efficiency.
