This thesis presents new methods for the characterization of vegetable
oils, with focus in olive oil, according to geographical and botanical
origin, genetic variety and other issues influencing product quality. A
wide variety of analytical techniques have been employed, such as
various chromatographic techniques (different gas and liquid
chromatography methods), an electronic nose, infrared spectroscopy and
expert-panel evaluation. Several families of minor compounds, with
interest as adulteration markers, have been used for method
development, including tocopherols, sterols, phenolics, alcohols,
proteins and others. Most methods have been enhanced by the application
of multivariate chemometrics. The proposed analytical techniques are of
interest to investigate fraudulent actions and practices which are
detrimental to product quality.
