The paper "Assessment of multiple stable isotopes for tracking regional and organic authenticity of plant products in Hesse, Germany", the result of a collaboration between FiBL, Agroisolab GmbH, the University of Giessen and the University of Freiburg, has been published in the journal "Isotopes in Environmental and Health Studies".

(Frankfurt, 17.05.2021) The data analysed in this paper originally came from the project Wasserzeichen, in which FiBL Germany and Agroisolab GmbH from Jülich took a total of over 1.000 samples of various agricultural plant and animal monoproducts, mainly from the German state of Hesse, and analysed them for their isotopic composition. The isotopic compositions 18O, 2H, 15N, 13C and 34S were investigated with the aim of verifying the suitability of isotopic analysis as an investigation method for tracing the regional origin of agricultural raw materials. With the help of the data, a database of Hessian products was set up, which is freely accessible at Xenia Gatzert
