| 摘 要： | 以4种香辛料和2种干制海鱼为材料，通过直接荧光过滤技术/平板计数法（DEFT/APC）比较辐照前后DEFT计数和APC计数的差异，判断食品是否经过辐照处理。试验结果表明，当log(DEFT/APC)>40时，表明产品至少已进行过10kGy剂量的辐照处理，DEFT/APC法的检测灵敏度与样品初始菌数及D10值相关。

| Abstract: | The Direct Epifluorescent Filter Technique/Aerobic Plate Count technique (DEFT/APC）can be used to identify the irradiated food by comparing the DEFT and APC counts of the samples prior to the irradiation and after. This technology was tested by using spice and dried marine fish as testing materials in this study. The results shows that the index, log(DEFT/APC)>40, can indicate that the samples have been irradiated at a dose level higher than 10 kGy. It also indicates that the detecting sensitivity was affected by the initial value of APC and D10 value of the samples. |
