Beverage Fraud Prevention using Isotope Fingerprints
The beverage industry suffers from fraudulent activities that include incorrect labeling of products and adulteration, which has a significant impact on consumer safety, brand names, and reputation.
Stable isotope measurements can differentiate between beverage samples that otherwise share identical chemical composition. This differentiation is given by the isotope fingerprints. The isotope fingerprint in beverage products is region- or process-specific, which means that products can be differentiated based on geographical region (e.g. wine or tequila ), agricultural sources (e.g. whiskey), and brewing processes (e.g. sake). Fraudulent practices such as mislabeling, sugar addition, or watering of wines and spirits can be unraveled.
