二维液相色谱在食品检测方面的应用进展

Application Progress of Two-Dimensional Liquid Chromatography in Food Detection

色谱技术在食品分离分析方面应用广泛。随着食品工业的发展,对现代分析技术提出了更高要求,二维液相色谱在揭示食品复杂基质组成、提供高分离能力和未知调味化合物识别方面具有明显优势。二维液相色谱通过将两个独立的色谱分离过程组合到一起实现。文章首先介绍了二维液相色谱技术,然后对二维液相色谱在食品溯源和安全、食品质量和添加剂、食品营养和健康方面的应用展开了讨论。随着技术的发展,二维液相色谱在食品分离分析方面的应用价值将会持续增大。

Chromatography is widely used in food separation and analysis.With the development of food industry,higher requirements are put forward for modern analytical techniques.Two-dimensional liquid chromatography has obvious advantages in revealing the complex matrix composition of food,providing high separation ability and identification of unknown condiment compounds.Two-dimensional liquid chromatography is achieved by combining two independent chromatographic separation processes.In this paper,two-dimensional liquid chromatography is introduced firstly,and then the application of two-dimensional liquid chromatography in the aspects of food traceability and safety,food quality and additives,food nutrition and health is discussed.With the development of technology,the application value of two-dimensional liquid chromatography in food seperation and analysis will continue to increase.
