Chemometric applications to assess quality and critical parameters of virgin and extra-virgin olive oil. A review
(Elsevier Science, 2016-03)
Today virgin and extra-virgin olive oil (VOO and EVOO) are food with a large number of analytical tests planned to ensure its quality and genuineness. Almost all official methods demand high use of reagents and manpower. ...
High-throughput determination of phenolic compounds in virgin olive oil using dispersive liquid-liquid microextraction-CZE microextraction-capillary zone electrophoresis
(Wiley Vch Verlag, 2013-06)
This article reports a simple methodology using dispersive liquid-liquid microextraction (DLLME) combined with CZE. It has been applied for the simultaneous determination of phenolic compounds such as caffeic, gallic, ...
