Research progress in the application of surface-enhanced Raman Spectroscopy method in food safety detection

In recent years, frequent food safety incidents at home and abroad have increased the public''s attention to food safety issues. Therefore, the ability to quickly, sensitively and reliably assess food quality and safety is particularly important in the food industry. Therefore, it is imperative to develop high-performance detection technology to meet the needs of food safety. Owing to the remarkable performances of high specificity, excellent sensitivity, nondestructive, and multiplexing capability, surface-enhanced Raman scattering (SERS) have performed prosperous applications and gained impressive progress in food safety. Herein, we introduced the theoretical basis of SERS technology, summarized the active substrates for the enhancement of SERS signals, reviewed the application research progress of food safety detection based on SERS method, and discussed its future trends and perspectives. These efforts are intended to provide recommendations for researchers to select appropriate SERS methods according to the requirements of specific food safety detection applications.
