Sensing and Instrumentation Technologies for Food Safety

The EMFSL Sensing Technologies group focuses on the development of optical sensing methods for non-destructive, rapid, and/or automated inspection and screening of food materials and food processing equipment to reduce food safety risks. Research areas include:

  • Hyperspectral and multispectral imaging using visible/near-infrared reflectance and UV/violet-excitation fluorescence
  • Whole-surface inspection of fresh produce for contamination detection
  • Raman chemical imaging for food authentication and adulterant detection
  • Handheld fluorescence imaging for cleaning and sanitation inspection (patented)
  • Laser-induced fluorescence (LIF) imaging for in-field contamination inspection for fresh produce
  • Gradient temperature Raman spectroscopy (GTRS)
  • Online poultry wholesomeness inspection (patented and licensed)

Current project, 2016 - 2021: Sensing Technologies for the Detection and Characterization of Microbial, Chemical, and Biological Contaminants in Foods

Previous project, 2011 - 2016: Development of Sensing and Instrumentation Technologies for Food Safety and Sanitation Inspection in Fresh Fruit and Vegetable Processing
