摘　　要：目的探讨和建立鸡肉中菌落总数检测结果的不确定度评定方法。方法依据《JJF1059-1999测量不确定度评定与表示》和《GB4789.2-2010食品安全国家标准食品微生物学检验菌落总数测定》,以及相关统计学方法对样品不确定度进行评定。结果依据所采用的方法,对同一样品测定10次菌落总数不确定度为0.0826。结论本文采用的评定方法,可以对单个样品菌落数检测结果不确定度作出估计,比较适用于日常工作中菌落计数的不确定度评定。Objective To study and develop the uncertainty evaluation methods in detection of aerobic plate count in chicken. Methods Based on JJF1059-1999 Evaluation and Expression of Uncertainty in Measurement, GB4789.2-2010 Microbiological Examination of Food Hygiene-Detection of Aerobic Bacterial Count, and related statistical methods to evaluate uncertainty of the samples. Results According to the methods used, the uncertainty was 0.0826 based on 10 determination of the same pork sample under the same condition. Conclusion Evaluation method used in this study can estimate the uncertainty of test results of a single sample, which is suitable to evaluate uncertainty of colony count in the daily work.
