Almost seven years ago, FE featured in this column a new “microtag” technology from TruTag Technologies, which could be used to track and trace high-value food items—those which are often stolen and/or counterfeited. For more on this tagging technology, see “A grain of sand, a whole lot of track and trace,” FE Engineering R&D, June 2014.
Borrowing on TruTag’s hyperspectral scanning technology to locate placed microscopic tags in a food product, its sister company, HinaLea Imaging has applied the same technology to provide an intelligent, autonomous and cost-effective imaging solution to track down dangerous pathogens—such as E. coli or Listeria monocytogenes in food and beverage products.
