摘 要：
Growth characteristics of pathogenic bacteria in refrigerated chicken with 60Coγ irradiation of different doses during storage were investigated to develop a pathogenic bacteria inactivation method using 60Coγ irradiation for refrigerated chicken storage. Pathogenic bacteria inactivation efficiency irradiated by 60Coγ in refrigerated chicken was evaluated through survival rate,which is the irradiation dose to keep 10% microorganism alive (D10). The D10s of total number of bacterial colony,E. coli 10003,and two strains of Campylobacter jejuni named 33560 and CY04 in refrigerated chicken after 60Coγ irradiation were 1.434,0.408,0.175 and 0.2 kGy,respectively. The total numbers of bacterial colony in vacuum packaged chicken samples after 3 and 5 kGy irradiation and following storage at 0-4 ℃ for 21 and 28 d were measured to be 5.66 and 4.90 lg (CFU/g),respectively,which meet the hygienic standard of poultry products.
