Dynamic isotope model to trace the geographical origin of agricultural products


The goal of this Marie Sklodowska-Curie funded program is to boost technology transfer and responsible research and innovation in plant sciences. Consumers are paying increasing attention to the geographic origin of agricultural products. The abundance of stable oxygen isotopes (18O) in precipitation shows a longitudinal and latitudinal dependent natural variation which is imprinted in plant material. This natural variability of stable oxygen isotopes in plants can therefore form the scientific basis for a tool that allows identifying the origin of plant products. During the project a new dynamic spatial isotope model that combines already developed models for oxygen isotope composition of precipitation with plant enabled isotope models will be created. The goal is to develop a new approach allowing probability estimates of the geographical origin of plant derived organic material with increased precision and improved general applicability.
