Advancement of rapid detection of meat quality and safety by using spectral imaging technology

As a rapid and non-destructive detection technology,spectroscopy has been widely used for assessing meat quality and safety. It can be used as rapid,online,accurate and nondestructive detection technology which is one of the important methods for quality and safety detection of fresh meat. Near-infrared spectroscopy,Raman spectroscopy,hyperspectral imaging technique and fluorescence spectroscopy are main non-destructive technologies used at present. In this paper,the important applications and research advances of these spectroscopies in fresh meat quality and safety inspection are reviewed. The applications of the spectral technologies are wide,including the analysis of nutritional components such as water,protein and fat; the evaluation of eating quality of meat that includes tenderness,marbling,color and freshness; the detection of meat quality that includes water-holding capacity; and the evaluation of meat safety quality that consists microbial contamination,etc.The problems of these spectral technologies are discussed,and the prospects of the technology combined with computer vision for the development of online testing equipments in order to accomplish comprehensive evaluation of the quality and safety of fresh meat into practical application are presented.
