The authors of this study (purchase required) report that they systematically separated and authenticated the triacylglycerols composition of milks from holstein cattle, goats, mongolian horses, bactrian camels, yaks and buffaloes, using supercritical fluid chromatography coupled to high-resolution mass spectrometry (SFC-Q-TOF-MS). Subsequently, the fingerprinting of triacylglycerols from different livestock milks was modelled using chemometric methods. The results showed that the statistical grouping of different livestock milks was consistent with the species taxonomy, and the accuracy of internal as well as external validation was satisfactory.
They conclude that this work not only provides an innovative strategy for authentic traceability of livestock milk, but also offers potential for the establishment of nutritional databases.
