Compound-specific isotope analysis to improve food traceability

, 2017
The scandals of recent years have left their mark on consumer confidence in food products. For this reason there is increasing demand for analytical techniques able to provide data on issues such as the traceability, authenticity and origin of foods and beverages. Stable isotope ratios have been used for food authentication for thirty years, and in the
