Geographic tracing of cereals from South Tyrol (Italy) and neighboring regions via Sr/Sr isotope analysis.

The protection and promotion of agricultural niche products can be supported by the application of analytical techniques able to link food to its territory. This study aimed at exploring the possibility to discriminate between cereal samples from South Tyrol (Italy) and the neighboring regions (Trentino, East Tyrol, and North Tyrol) by their Sr/Sr ratios. Soil and grain (different species) samples were collected from around 100 fields in two sampling campaigns.
