Research progress on the application of mid-infrared reflectance spectroscopy (MIRS) in food detection

中红外光谱技术是一种利用物质对光的吸收、散射、反射与透射等特性来确定其成分含量的检测技术。该技术作为食品分析方法之一,在食品领域中应用广泛,从气体到液体,从匀浆到粉末,从固体材料到生物组织等样品均可进行快速精准地检测与定性定量分析,具有快速无损,安全高效,多组分同时测定等特点。该文在对中红外光谱技术的工作原理与常用食品品质检测方法的主要优缺点简要说明的基础上,综述了中红外光谱技术在食品产地溯源、真假掺伪、品种鉴别与品质检测等方面的应用实例与研究进展,提出存在问题与解决方法,并对其发展前景予以展望。

Mid-infrared reflectance spectroscopy (MIRS),as one of the food analysis and detection techniques,uses the properties of light absorption,scattering,reflection and transmission to determine its component content. With wide applications in the field of food science,MIRS can perform the analysis from gas to liquid,from homogenate to powder,from solid materials to biological tissues. As a consequence,samples can be quickly and accurately detected and qualitatively and quantitatively analyzed. It has the characteristics of rapid,non-destructive,safe and efficient,and simultaneous determination of multi-components. Based on the brief introduction of working principle of MIRS and the main advantages as well as disadvantages of common food quality detection methods,this paper also summarized the application examples and research progress of MIRS in origin traceability,adulteration,variety identification and quality detection. The main problems and solutions of MIRS were put forward,its development prospects were also prospected.
