Sensing and Instrumentation Technologies for Food Safety
www.ars.usda.gov/nea/barc/emfsl/sensingtech
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)
