Reference Materials and Calibration for Stable Isotope Ratio Analysis in Food

Luana Bontempo, Luca Ziller, Federica Camin
Abstract:
The stable isotope ratios of the five bio elements carbon, nitrogen, hydrogen, oxygen and sulphur have frequently been used in the last few decades to determine the authenticity and traceability of many food commodities. In this paper, issues regarding calibration, suitable reference materials and correct methods to obtain reliable results with this potentially powerful technique are critically discussed and commented.
