McGill researchers target honey fraud with AI

Mass spectrometry and AI have been employed by researchers at McGill University, Canada, to verify the origin of honey and cut fraud.

Stéphane Bayen, Associate Professor and Chair of McGill’s Department of Food Science and Agricultural Chemistry, said that honey is one of the most fraud-prone commodities in global trade.

“It often involves mislabelling where it was produced or the types of flowers that bees collected nectar from,” he said in a statement.

Honeys made from a single flower are often more expensive, prompting some producers to intentionally mislabel honey in order to charge more. Others may do so unknowingly, given that tracking exactly where bees collect nectar can be challenging.

The new method can determine what type of flowers the bees visited to produce a particular honey.

Until now, authenticating honey has been done through pollen analysis, a technique that fails after honey is processed or filtered. The new approach uses high-resolution mass spectrometry to scan honey at a molecular level to create a unique chemical fingerprint.

Machine learning algorithms then read the fingerprint to verify the honey’s origin. To check the accuracy of their method, the researchers tested it on a variety of honey samples and compared the results to honey from known botanical sources.
