摘要
为控制北京烤鸭中的微生物,使用了冷冻与电离辐射相结合的技术。利用^(60)Coγ射线源在冷冻条件下进行照射,平均吸收剂量为2kGy。经这样处理的烤鸭,微生物指标达到了部颁标准并且在营养成份、维生素含量等方面与未经辐照的烤鸭无明显差异。经实验证明,辐照后的北京冷冻烤鸭在卫生安全性方面是完全可靠的。
The irradiation technique combined with freezing has been used tocontrol the microorganism in Beijing Roast Duck. Cobal-60 was chosen as γ-ray sou-rce. The absorbed dose was 2 kGy on an average. After irradiation, the microbe cou-nts have reached the tolerable. Compared with untreated ducks, the irradiated onesshowed no remarkable change in nutrition, chemistry, vitamin etc. It has been provedthrough tests that the irradiated frozen Beijing Roast Duck is wholesome.
