Application and research progress of spectroscopy in meat detection

Spectroscopy is a qualitative and quantitative technique to analyze specific component of an object based on the principle that specific structure of an object such as internal atoms and molecules has different absorption characteristics of electromagnetic wave. In the paper，detection principles and techniques of infrared spectroscopy and hyperspectral technology in meat detection were summarized. Current status of the application of infrared spectroscopy and hyperspectral technology in meat detection were reviewed from meat origin and variety inspection；meat quality （tenderness，freshness，water holdup，marble，etc.）. The problems in spectroscopic detection techniques were presented and the development trend of meat detection was prospected.
