Food Chemistry, 2020
Until now, there has been a lack of analytical methods that can reliably verify the authenticity of organically grown plants and derived organic food products. In this study, stable isotope ratio analysis of hydrogen (H, δ2H), carbon (C, δ13C), nitrogen (

Both stable isotope ratio and content of carbon (C), hydrogen (H), oxygen (O), nitrogen (N), and sulfur (S) were employed to evaluate the possibility of geographical origin discrimination for onions grown in different regions in Korea.

Referencing strategies and techniques in stable isotope ratio analysis.
Rapid Communications in Mass Spectrometry, 2001Abstract Stable isotope ratios are reported in the literature in terms of a deviation from an international standard (δ‐values). The referencing procedures, however, differ from instrument to instrument and are not consistent between measurement facilities.

Stable isotope ratio analysis for authentication of lamb meat.
Meat Science, 2003The effectiveness of the analysis of stable isotope ratios ((13)C/(12)C and (15)N/(14)N) in fractions of lamb meat, measured by isotope ratio mass spectrometry, was evaluated as a method of feeding and geographical origin authentication. Analyses were carried out on meat from 12 lamb types, produced in couples in six European countries (country of ...
