Abstract
A quantitative method was established to determine the presence and composition of mono-, di-, and triglycerides of olive oils of superior gradevia 13C NMR. The total diglyceride content and the ratio ofsn-1,2- andsn-1,3-diglycerides in extra virgin oils extracted from different olive cultivars were correlated with maturity. The correlation can be applied to identify the oils by variety. No monoglycerides were detected in the oils examined.
