Figure 1

Typical proton NMR spectrum of eVOOs with highlighted the characteristic peaks of fatty acids and glycerol moieties used for the determination of fat percentage. In addition, the expansion shows the satellites of the methyl peak at 0.85 ppm (I) superimposed to that of linolenic at 0.98 ppm (E).
