| 摘 要： | 研究60Co-γ射线辐照对凤爪软罐头的灭菌作用及对其品质的影响。通过60Co 以0、6、8、10kGy 剂量辐照软罐头包装凤爪，分别在贮存0、20、40、60d 时检测样品中菌落总数、大肠菌数、致病菌以及脂质氧化。结果表明：辐照后各处理组的菌落总数远低于对照组，60d 后6kGy 处理组为155CFU/g，低于国家限定标准；大肠菌群和金黄色葡萄球菌、志贺氏菌、沙门氏菌等致病菌未检出。贮存过程中，TBARS 值均较低，60d 后，处理组TBARS 值无明显增加。因此，60Co-γ辐照处理凤爪，能够有效杀菌，达到延长货架期作用。

| Abstract: | Total amount of bacteria, amount of coliform bacteria, amount of pathogenetic bacteria and TBARS value of softcanned chicken paws irradiated with different doses of 60Co-γ were measured at intervals of 20 d up to 60 d of storage. Results showed that the total amount of bacteria in 60Co-γ-treated chicken paws was much lower than that in untreated chicken paws, and 6 kGy dose-treated chicken paws stored for 60 d revealed a value of 155 CFU/g, lower than limit value of relevant Chinese national standard. No coliform bacteria, Staphylococcus aureus, Shigella, Salmonella were detected. The TBARS value was kept at lower levels and no significant increase was observed over the whole storage period. Accordingly, 60Co-γ irradiation can effectively inactivate microorganisms and prolong sheflife of chicken paws. |
