liquid chromatography with electrospray ionization–high-resolution/accuracy
Fourier transform mass spectrometry (RPC-ESI-FTMS) and chemometrics
were exploited to evaluate the influence of horizontal centrifugation
by two- or three-phase decanters on the content of major phenolic
secoiridoids in extravirgin olive oils (EVOOs). Despite the occurrence
of other potential sources of variability typical of commercial olive
oils, horizontal centrifugation was found to play a primary role,
with a general increase of secoiridoid content occurring when two-phase
decanters were used. As emphasized by principal component analysis
(PCA), the increase involved preferentially oleacin and oleocanthal,
when oxidative deterioration was purposely minimized during and/or
after production, and oleuropein and ligstroside aglycones, when no
vertical centrifugation was performed at the end of the productive
cycle. The influence of the type of horizontal centrifugation was
also emphasized by the elaboration of RPC-ESI-FTMS data based on hierarchical
cluster analysis (HCA) and linear discriminant analysis (LDA).
