乳品掺假检测技术研究进展

Research Progress of Adulteration Detection Technology in Dairy Products

掺假问题一直是影响乳品质量安全的重要因素,从最初往乳品中掺入氮素、植物性蛋白、三聚氰胺等物质,再到如今用“低价乳”掺入“高价乳”中进行售卖,各种掺售问题层出不穷。发展快速、高效、高质量的乳品掺假检测技术尤为重要。目前较常见的检测技术基本是基于乳中脂肪、蛋白质和核酸等特性。本文对乳品检测技术中的电泳、近红外光谱、液相色谱、气相色谱、酶联免疫吸附法、低场核磁共振等进行综合概述,以促进乳品掺假检测技术发展,保证乳品质量安全。

Adulteration has always been an important factor affecting the quality and safety of dairy products.From the initial adulteration of nitrogen,vegetable protein,melamine and other substances into dairy products,to the current adulteration of low-priced milk into high-priced milk for sale,various adulteration problems emerge one after another.It is particularly important to develop fast,efficient and high-quality dairy adulteration detection technology.At present,the common detection techniques are basically based on the characteristics of fat,protein and nucleic acid in milk.In this paper,electrophoresis,near infrared spectroscopy,liquid chromatography,gas chromatography,enzyme-linked immunosorbent assay,low-field nuclear magnetic resonance and so on in dairy detection technology are comprehensively summarized to promote the development of dairy adulteration detection technology and ensure the quality and safety of dairy products.
