Fraudulent practices in food production, especially false claims of geographical origin, cause billions of dollars in economic damage every year. Botanists at the University of Basel have now developed a model based on stable isotope measurements, that can be used to determine the origin of food in an efficient and low-cost manner.

“With minor adjustments to the parameters, our model can be used to determine all plant products,” says Professor Ansgar Kahmen, who led the research project. This makes it possible to simplify and speed up conventional isotope analysis by accurately simulating the regions of origin of agricultural foodstuffs.
