Abstract:Non-destructive testing（NDT）is a non-invasive method and technique for testing and analysis without destroying the tested samples.The use of NDT method for rapid detection of foodborne pathogenic bacteria is of great significance to food safety.In this paper，the basic principles of three major NDT techniques（near infrared spectroscopy，hyperspectral technique and electronic sensory technology），their applications in the detection of common food pathogenic bacteria，and the latest research progress were introduced and analyzed，so as to provide a reference for the further application of NDT technique in food.
