Forensic food microscopy

We are leaders in the area of Forensic Food Microscopy and Food Forensics. Forensic microscopy defines that we not only identify foreign material, but that we also investigate the sample characteristics to determine when and how the foreign material got into the food product. This includes determination of fraudulent activity where objects are added to the product post-production.

Foreign Material Identification

Foreign Material Identification refers to the chemical/microscopic analysis and classification of physical contamination and unknown particulate matter found in foods.


In addition to stereo and compound microscopes, we utilize SEM-EDX, FT-IR, and other instruments.

Non-Destructive Testing

In most cases we are able to examine and run biochemical reactions on the surfaces of the samples without changing the sample in any significant way, however a trace of discoloration may remain on the surface.
