The chemical changes associated to the autooxidation process of LA were detected by Raman spectroscopy and interpreted in the light of DFT calculations. The success of Raman spectroscopy in probing the oxidation state of a fatty acid, coupled to a simpler setup and virtually no sample preparation, renders this technique a very useful and promising tool, namely for assessing the quality of edible oils and other lipid-containing food products in situ.
