【摘要】 :为研究辐照对真空包装鲫鱼的保藏作用进行本试验。发现 30℃条件下不适于辐照鲫鱼的保藏。在 4℃条件下 ,2 .5kGy的辐照可明显延长鲫鱼的保存期 ,随着辐照剂量的增加 ,保存期不断延长。对辐照后鲫鱼进行微生物分析发现 ,辐照可明显地降低鲫鱼试样中菌落总数和大肠菌群数 ,1.0kGy的辐照剂量可使鲫鱼中大肠菌群的MPN值小于 30 / 10 0 g。 1.0kGy的辐照剂量可有效地杀灭鲫鱼中人工污染的志贺氏菌 ,1.5kGy的辐照剂量可有效地杀灭鲫鱼中人工污染的沙门氏菌更多还原

【Abstract】 The effect of irradiation at doses of 0～10 kGy on the shelf-life of crucian was determined. The results showed that irradiation could not prolong the shelf-life of crucian kept at 30℃. While the crucian were kept at refrigerator (4℃),the irradiation could propong the shelf-life, effectively reduce the total aerobic plate count and the number of coliform. 1.0 kGy of irradiation could effectively reduce the number of coliform to less than 30/100 g and eliminate Salminella inoculated in crucian. 0.5 kGy of irradiation could eliminate Shigella Shigae inoculated in crucian.
