Ros, Alessio Da published the artcileComplementary untargeted and targeted metabolomics for differentiation of extra virgin olive oils of different origin of purchase based on volatile and phenolic composition and sensory quality, Safety of 3-Pentanol, the main research area is metabolomics extra virgin olive oil sensory quality; extra virgin olive oil; phenols; sensory attributes; volatiles aroma compounds.
In order to differentiate the extra virgin olive oils (EVOO) of different origin of purchase, such as monovarietal Italian EVOO with protected denomination of origin (PDO) and com.-blended EVOO purchased in supermarkets, a number of samples was subjected to the anal. of volatile aroma compounds by both targeted gas chromatog./mass spectrometry (GC-MS) and untargeted profiling by comprehensive two-dimensional gas chromatog./mass spectrometry (GC×GC-TOF-MS), anal. of phenols by targeted high-performance liquid chromatog./mass spectrometry (HPLC-DAD-ESI/MS), and quant. descriptive sensory anal. Monovarietal PDO EVOOs were characterized by notably higher amounts of pos. LOX-derived C6 and C5 volatile compounds, which corresponded to the higher intensities of all the assessed pos. fruity and green odor sensory attributes. Com.-blended EVOOs had larger quantities of generally undesirable esters, alcs., acids, and aldehydes, which coincided with the occurrence of sensory defects in many samples. Many minor volatile compounds that were identified by GC×GC-TOF-MS were found to differentiate each of the two investigated groups. The differences between the groups with respect to phenols and taste characteristics were evident, but less pronounced. The results that were obtained in this study have undoubtedly confirmed the existence of the large heterogeneity of oils that are sold declared as EVOO. It was shown that GC-MS, GC×GC-TOF-MS, and HPLC-DAD-ESI/MS analyses have complementary outputs, and that their use in combination has advantages in supporting the results of sensory anal. and objectively differentiating these groups of EVOO.
