Abstract. Near-infrared (NIR) spectroscopy, as a new optical inspection technology, has been widely used in food industry. This paper firstly introduced the theory of NIR spectroscopic analysis, compared spectroscopic data pretreatment with analysis and identification by models, and then expounded NIR spectroscopy‘s important applications in meat industry and the research progress in this field. The applications include quantitative prediction of nutritive indexes in meat, quantitative prediction of quality parameters in meat, and applications in identifying meat adulteration and meat freshness. At the end, it looked to the future of this technology based on the current development tendency.
