Giuseppe Perretti
The aim of this work is to determine the feasibility of applying SFE technique by supercritical CO2, to the gravimetric measurement of lipids in olives by verifying the feasibility of extractions, studying the analytes solubility in SC-CO2, optimizing the preparation of sample, appraising the repeatability of the data obtainable with the adopted method. The olive cultivar "Moraiolo and two different supercritical fluid laboratory instruments were used. Initial trials were performed to verify the extractability of the oil from matrix. The degree of solubility was determined by the quantitative amount of extracted and collected solute, reported for the quantity of solvent used (CO2). Once the feasibility was established and the solubility was studied, it was necessary carry out specific trials to find a better formula for the sample preparation. This involved type of matrix (humidity, structure, oil content, density, etc.) and equipment commonly available in laboratories deals in food product analysis.
