摘　　要：采用ATP发光法检测辐照对冷却猪、鸡肉ATP发光强度的影响,并对其他试验因素是否对样品ATP发光强度产生影响进行了分析。结果表明:ATP标准品的浓度与发光强度呈显著的正相关,ATP标准品发光强度与辐照剂量表现为显著的负相关;辐照冷却肉的细菌ATP发光强度随辐照剂量的变化趋势呈现为倒"S"形特征,其中6.0kGy辐照时发光强度最大,4.0、8.0kGy剂量辐照时强度最小;无菌水、灭菌样品未对ATP发光强度造成干扰,而未辐照大肠杆菌浓度与ATP发光强度之间呈显著线性正相关,相关系数达到0.9437。The effect of irradiation on cooled pork and chicken was detected with ATP luminous intensity method.The influences of other factors to ATP luminous intensity were also dicussed.There was positive correlation between ATP standard concentration and ATP luminous intensity,and negative correlation between irradiation dosage and ATP luminous intensity.The trend of ATP luminous intensity of cooled pork and chicken after irradiation was inverse＂S＂,and the maximum ATP luminous intensity appeared at 6.0 kGy,and minimum at 4.0 and 8.0 kGy.Sterilized water and sterilized pork had no interference to ATP luminous intensity of the samples.There was significant positive correlation between E.coli 10003 concentration and ATP luminous intensity,the coefficient correlation was 0.9437.
