OILs quality ASAP: Detecting defected oils by direct MS using Atmospheric Solids Analysis Probe

Abstract

The main objective of this research work is to create an analytical method capable to differentiate between the qualities of olive oils (EVOO/VOO or LOO), through the use of a relative novel technique ASAP-Q-TOF(MS) and metabolomics-based approach. With this technique, it is intended to find a different point of view and a complementary analysis to the known “PANEL TEST”, giving a faster, cheaper and more objective classification of the samples. This major objective can be divided into several partial objectives: - A bibliography review about the olive oil, which includes composition, properties and benefits, quality classification, among others. - Develop a full spectrum acquisition method by using ASAP-QTOF MS. - Optimization of the sample introduction/ionization through a Design of Experiments (DoE) using Design Expert software - Study of the addition of different internal standards - Metabolomic design for data processing, comparing PARAFAC2 and XCMS free package from R - Statistical treatment of the data to find markers of quality to create a model which permits to classify the olive oils as EVOO/VOO or LOO.
