With the increasing concern of the society on food safety issues, the market of food safety testing technology has begun to expand and mature. There are increasing requirements for food safety testing such as accuracy, extensiveness and speed. The applications of spectral detection technology in the field of food safety detection are increasing with the advantages of nondestructive and high efficiency. Among all, near infrared spectroscopy, Raman spectroscopy, hyperspectral imaging detection technology, X ray, fluorescence spectrum detection technology and terahertz spectroscopy detection technology are particularly prominent. Because of the different production principles and characteristics, the above spectral detection techniques have different applications in different food safety detection fields, and the applicable range is affected by the performance of penetration, accuracy, detection speed and resolution of organic matter. This paper described the principles and characteristics of the above spectral detection techniques, summarized the current research results at home and abroad, and looked forward to the application of the spectral detection technology in the field of food safety.
