摘要: 体细胞数是反映生鲜牛乳质量及奶牛健康状况的重要指标。2018年我国食品安全国家标准首次计划加入体细胞数限量值分级标准,体细胞数准确检测直接影响生乳产品正确分级。本综述基于体细胞对乳制品质量的重要性,对国内外生鲜牛乳体细胞限量标准进行了总结和比较;对现有的体细胞检测方法和原理进行了概括分析,阐明了不同原理仪器的方法性能的关键检测参数指标,指出了计量校准对于保证体细胞检测仪器结果准确可比的重要性。

Abstract: Somatic cell number is an important indicator of indicating raw milk quality and health status of dairy cows. In 2018,China’s national food safety standards plan included somatic cell number limit grading standards in the first time,thus the accurate detection of somatic cell number will directly affect the correct grading of raw milk products. Based on the importance of somatic cells to the quality of dairy products,we summarized and compared the somatic cells limit standards of raw milk at home and abroad in this review. We analyzed the existing somatic cell detection methods and principles,as well as the key detection parameters of the method performance of different principle instruments. We also outlined the great importance of establishing measurement calibration for ensuring accurate and comparable results of somatic cell detection instruments.

Key words: somatic cell number, raw milk, national standard, measurement, calibration
