The current study investigated the synergistic effect of combined X-ray irradiation (0.5, 1.0, 1.5, and 2.0 kGy) and aqueous chlorine dioxide (ClO₂) treatment (10, 20, 30, and 50 ppm) on Salmonella enterica serovar Typhimurium biofilms on the surfaces of quail egg shells. The synergistic effect was not dependent on the X-ray irradiation dose or ClO₂ concentration. The synergistic reductions of biofilms after X-ray/ClO₂ treatment on the egg shells were −0.1–1.1 log CFU/egg. The largest reduction was 1.1 log CFU/cm² after a 2.0 kGy X-ray and a 20 ppm ClO₂ treatment. No significant change (P > 0.05) was observed in the Hunter colors (L*, a*, and b*) and shear force (shell thickness) of the egg shell surfaces after single or combined treatments. Similarly, no significant changes (P > 0.05) were observed in the same parameters on the egg shell surfaces when a combination treatment of minimum X-ray doses/ClO₂ concentrations and a combination treatment of maximum X-ray doses/ClO₂ concentrations were applied separately. The results indicated that the combination treatment of 2.0 kGy X-ray/20 ppm ClO₂ could be used in the egg production, processing, and distribution processes to enhance food safety without causing changes to the egg shell surface color and shell thickness.

当前的研究调查了联合X射线辐射（0.5、1.0、1.5和2.0 kGy）和二氧化氯水溶液（ClO ₂）处理（10、20、30和50 ppm）对肠炎沙门氏菌血清鼠伤寒生物膜的协同作用。在鹌鹑蛋壳的表面。协同作用不依赖于X射线辐射剂量或ClO ₂浓度。X射线/ ClO ₂处理对蛋壳产生的生物膜的协同减少作用为-0.1–1.1 log CFU /蛋。经过2.0 kGy X射线和20 ppm ClO ₂处理后，最大减少量为1.1 log CFU / cm ²。无重大变化（P 单次或联合处理后，在蛋壳表面的亨特颜色（L *，a *和b *）和剪切力（壳厚度）中观察到> 0.05）。同样， 当同时使用最小X射线剂量/ ClO ₂浓度和最大X射线剂量/ ClO ₂浓度的组合处理时，在蛋壳表面的相同参数上也没有观察到显着变化（P > 0.05）。单独应用。结果表明2.0 kGy X射线/ 20 ppm ClO ₂的组合处理可用于鸡蛋的生产，加工和分配过程，以提高食品安全性，而不会引起蛋壳表面颜色和壳厚度的变化。
