Fresh milk, yoghurt and cream are often local products with seemingly little doubt about the origin. This can be deceiving as most of the raw milk is nevertheless processed in big dairies. The origin of a dairy product can be of importance, because some regions might be associated with negative news and on the other hand certain origins might add value to the product.
Isotope ratio mass spectrometry (IRMS) can assure geographic origin and authenticity of dairy products at all points of the supply chain. By determining and interpreting the stable isotope ratios of carbon, nitrogen, sulfur, hydrogen and oxygen of any dairy product, the so-called isotope fingerprint (consisting of all five ratios) is established which is characteristic for the sample and can be compared to reference data from reference samples from different regions or to a database.
To achieve high geographical resolution and credible results, we use our global database, as well as our expertise and know-how to provide advanced customized origin testing by including more parameters. Any information on the samples such as suspected (not declared) origin, feeding scheme, organic/conventional etc. is helpful.
