Different analytical methods widely used for food product origin identification have been currently developed.
They are: isotopic ratio of light elements, element analysis,
nuclear magneticresonance, chromatography profiling,
near and mid infrared spectroscopy methods

Despite the fact that isotoperatio mass spectrometry is
a powerful method providing comprehensive information
on geographic origin of the test object [5, 13], there are
more publications on applying different combinations of
specified above test methods.

The purpose of this work was to assess the possibility of
performing compound specific isotope analysis of amino
acids by method based on gas chromatographic profiling
followed by determination of carbon isotope ratios for
meat geographic origin identification.
