Food safety is of paramount importance, and establishing a food origin traceability system is a core component of this effort. This system serves not only as a cornerstone for combating food fraud and regulating market order but also as a vital means to safeguard consumers’ right to information and trust, as well as to protect national tax revenue. Compared to traditional methods, spectral nondestructive testing technology is increasingly being applied in food origin traceability due to its advantages such as rapid detection, high sensitivity, ease of operation and nondestructive analysis of samples. This paper described the following 5 kinds of modern emerging spectroscopic detection techniques: Laser-induced breakdown spectroscopy (LIBS), hyperspectral imaging (HSI),X-ray fluorescence spectroscopy (XRF), Raman spectroscopy (RS) and Terahertz (THz) spectroscopy. It reviewed the fundamental principles of these 5 kinds of spectroscopic detection techniques and the latest research progress in the field of food origin traceability both domestically and internationally in recent years. The study also highlighted noteworthy aspects and areas for improvement in current research, aiming to provide theoretical foundations and technical references for the application of spectroscopic nondestructive testing technology in food origin identification.
