Agri-food traceability

Scientific research promoted by the “Provincia Autonoma di Bolzano Alto Adige” within the “NOI Capacity building I” funding frame (Decision n. 1472, 07.10.2013), in collaboration with Laimburg Research Centre and Eco-research srl.

An analytical method able to measure the strontium isotope (87Sr/86Sr) ratio in agri-food (case study on apples) was developed and applied to:

  • check the link between the plant and the soil analysing their 87Sr/86Sr ratios;
  • verify if Sr coming from agricultural practices significantly affect the 87Sr/86Sr of plants;
  • define the variability of the 87Sr/86Sr ratio intra- and inter-tree and its correlation with the soil 87Sr/86Sr ratio;
  • describe the Italian PGI and PDO apple production according to their 87Sr/86Sr ratio in comparison with non-GI apples.

TIOMI

The TIOMI project (2018-2020) is financed by the Autonomous Province of Bozen-Bolzano and involves different research partners: unibz, Laimburg Research Centre, and Eco-research srl.

Within this project, our task has the following aims:

  • Optimization of the sampling procedure and of the analysis of stable isotopes of Sr and of other light and heavy isotopes (H, O, B and Pb) in vegetal samples or in the xylem sap from trees;
  • Sampling and analysis of stable isotope ratios in fruit, cereal and woody samples from local, national and international origin.
