辐照对软罐头包装凤爪的杀菌作用和品质的影响

使用0、3、5、10kGy的60Coγ射线辐照软罐头包装凤爪,分别在贮存0、30、60、90d时检测样品中的菌落总数、大肠菌群、致病菌、TBARS值,并进行了感官评价试验.结果表明,贮藏90d后,辐照组的菌落总数分别为6.1×103、1.4×103、765cfu/g,在整个贮存期间均低于对照组,且未检出大肠菌群和致病菌...

EFFECT OF IRRADIATION ON STERILIZATION AND SENSORY QUALITY OF SOFT CAN PACKAGED CHICKEN FEET

The soft can packaged chicken feet were irradiated by 60Co γ-rays at 0, 3, 5 and 10kGy, and the aerobic plate count, enumeration of coliforms, pathogens, TBARS value and sensory characteristics were investigated during different storage times of 0, 30, 60 and 90d, respectively. The result showed that aerobic plate count of all treated groups were 6.1×103, 1.4×103 and 765cfu/g, respectively, and were all lower than that of control after 90d. Enumeration of coliforms, and pathogens of Staphylococcus aureus, Shigella, Salmonella were not detected. TBARS value of all groups increased during the storage time, and there was no significant difference between 3kGy irradiated group and control, which was 0.410 and 0.404 after 90d. Irradiation would not change the sensory quality of chicken feet obviously, and 60Co γ-rays irradiation was an effective sterilization method on soft can packaged chicken feet.
