Stable carbon isotope ratio measurements in milk fatty acids

The aim of this work was to apply isotope ratio mass spectrometry to differentiate organically and conventionally produced milk. For measurements milk samples were bought from supermarket and collected from organic farm. Measurements were done using GC/C/IRMS system. To achieve objective of this work δ13C ratios were analyzed in individual fatty acids of the milk. Objective of this work was achieved when individual milk samples were compered between each other with their δ13C ratios in C16:0 and C18:0 fatty acids
