目的：对速冻草莓中菌落总数检验结果进行不确定评定,确保检测结果准确可靠。方法依据GB4789.2-2010《食品安全国家标准食品微生物检验菌落总数测定方法标准》和依据 JJG1059.1-2012《测量不确定度评定与表示》,对速冻草莓样品中菌落总数进行了测定,建立数据模型,对引起检测结果的不确定因素进行了分析,并对其不确定度进行了评定,最终得到标准不确定度和扩展不确定度。结果扩展确定度为0.0824, k=2.13。结论菌落总数检测过程中,分散性对结果不确定贡献较大,因此测定结果的不确定度采用检测结果的分散性进行评定。

Objective The uncertainty of the total bacterial colony measurement detected in frozen strawberry was evaluated to ensure the detection results accurate and reliable. Methods According to the method of GB 4789.2-2010 and the method of JJG 1059.2-2012, uncertainty in total colony measurement was evaluated, and the result of uncertainty assessment in the detection of total colony in frozen strawberry was analyzed. Results The extended uncertainty was 0.0824 with k=2.13. Conclusion The dispersion is the major contribution of the uncertainty in the detection of total bacterial colony, so the dispersion of the rest re-sults was evaluated for the uncertainty of determination results.
