The values of D10 and D for the total bacteria in boiled dumplings under chill state were 2.04 kGy and 4.00 kGy, the value of D10 and D for E. coli were 1.25 kGy and 2.00 kGy. TBAS were increased significantly and excessed the trade standard by 5 kGy γ-irradiation. However, the TBAS would be decreased with addition of antioxidants. Lipid peroxide,volatile basic nitrogen,"a" value of color and "b" value of color showed a tendency of increase, and moisture content and Aw showed a tendency of decrease, which did not achieve a significant level(p.05) by 1 to 5 kGy doses of γ-irradiation. Total acidity, amino acid nitrogen and free fatty acid showed no significant differences between treated and control samples. Sensory evaluation values were decreased and were all well within the acceptable level by 1 to 5 kGy doses of γ- irradiation.

辐照能有效降低鲜熟水饺细菌总数和大肠菌群数量，鲜熟水饺中细菌总数和大肠菌群的 D10值分别为 2.04 kGy 和 1.25kGy，D 值分别为 4.00 kGy 和 2.00kGy；0～5kGy 辐照鲜熟水饺 TBA 值随辐照剂量增加而增加，5kGy 辐照已使之超过国家行业标准限量要求；辐照鲜熟水饺过氧化值、挥发性盐基氮、色差 a 值、色差 b值存在随辐照剂量增加而增加的趋势、水分含量存在下降趋势，但变化未达到显著水平(p.05)；对酸度、氨基酸态氮、水分活度、游离脂肪酸含量等其他理化指标没有显著影响；较高剂量辐照使产品感官质量降低，却都在可接受范围内； 4kGy 辐照使维生素 B1下降 31.94%，对维生素 E、蛋白、脂肪、氨基酸、不饱和脂肪酸含量无显著影响。
