In recent years, people pay more and more attention to food quality and safety, which are significantly relating to human health. Food adulteration is a world-wide concerned issue relating to food quality and safety, and it is difficult to be detected. Modern detection techniques (high performance liquid chromatography, gas chromatography-mass spectrometer, etc.) can accurately identify the types and concentrations of adulterants in different food types. However, the characteristics as expensive, low efficient and complex sample preparation and operation limit the use of these techniques. The rapid, nondestructive and accurate detection techniques of food adulteration is of great and urgent demand. This paper introduced the principles, advantages and disadvantages of the nondestructive analysis techniques and reviewed the applications of these techniques in food adulteration screen in recent years. Differences among these techniques, differences on data interpretation and future prospects were also discussed.
近年来，人们越来越关注食品质量和安全，这与人类健康密切相关。食品掺假是一个全球性关注的问题，关系到食品质量和安全，而且很难被检测到。现代检测技术（高效液相色谱、气相色谱-质谱联用仪等）可以准确识别不同类型食品中掺杂物的种类和浓度。然而，这些技术昂贵、效率低、样品制备和操作复杂的特点限制了它们的使用。因此，对食品掺假的快速、无损、准确检测技术有很大的需求。本文介绍了无损分析技术的原理、优缺点，并综述了近年来这些技术在食品掺假筛查中的应用。还讨论了这些技术之间的差异、数据解释的差异以及未来的前景。
