Abstract: Abstract: Dairy products are an indispensable food in our lives. Protein has a high content component in dairy products, and its changes greatly affect the quality and taste of dairy products. Proteomics is the core technology of current post-genomics and systems biology approaches. In this paper, the concepts, detection methods and data analysis of proteomics are reviewed, with emphasis on the study of differential proteomes in casein, milk fat globulin and whey protein through proteomics, so as to distinguish dairy products from different sources. The results provide an effective working idea for authenticity identification and quality safety of dairy products.

摘要： 摘 要：乳制品是我们居民生活中不可或缺的食品，蛋白质是乳制品中含量较高的成分，它的改变极大影响着乳制品的品质和口感，蛋白质组学是当前后基因组学、系统生物学方法的核心技术。本文综述了蛋白组学的概念、检测方法以及数据分析，重点介绍了通过蛋白质组学来研究酪蛋白、乳脂球蛋白和乳清蛋白中的差异蛋白质组，以此来区分不同来源的乳制品。这一结果为鉴定乳制品真伪提供了有效的工作思路，保障了乳制品的质量。
