Abstract：The problem of food safety has aroused people’s attention increasingly. The conventional analytical techniques have such disadvantages as complex operation process, long detection time and environmental pollution. Therefore, it is urgently needed to develop simple and time-saving methods that enable on-site nondestructive detection for food safety. Terahertz (THz) science and technology provides a new solution to the problem. In the present paper, a brief overview of the features of THz science and technology is given. In addition, the latest progress in the application of THz technology in food quality and safety detection is summarized. Problems encountered in its application in the field of food safety are also discussed.
