食品和饲料中三聚氰胺检测方法研究进展

Recent Advance in Determination Methods of Melamine in Foods and Animal Feeds

三聚氰胺是一种三嗪类含氮杂环有机化合物。由于其较高的含氮量而被添加于食品和饲料中,对动物和人体造成了一定的危害。本文综述了近期的食品和饲料中三聚氰胺检测的样品前处理技术和分析方法,主要包括高效液相色谱法、气相色谱-质谱法、液相色谱-质谱法和酶联免疫法等。

Melamine is a small polar tdazine compound. Due to its rich in nitrogen, it has been added to give a false impression of high protein content. Melamine added to food and animal feeds could possibly cause fatal kidney stones. Determination of melamine is therefore of large importance to ensure food safety. This article reviewed the modern methods of sample preparation and determination of melamine in foods and animal feeds including high-performance liquid chromatography, gas chromatography-mass spectrometry, high-performance liquid chromatography-mass spectrometry and enzyme-linked immunosorbent assay.
