Description:
Extra-Virgin oils possesses a characteristic aroma, taste and colour that distinguish it from other vegetable oils. The detection of aroma volatiles emitted by EVOO is of key importance in the quality control of this product. Physical-chemical techniques (GC, GC\MS, HPLC), chemical analysis and sensorial analysis (panel test) are the classical methods used for this purpose, but they are expensive, time consuming, and do not allow on- line measurements. In this work a sensors array based on pure and doped SnO2 solgel thin films, was used for the discrimination of different Mediterranean “single-cultivar” EVOOs. To confirm the sensor array responses, sensory analysis and analytical technique like Headspace-Solid Phase Micro Extraction \ Gas Chromatography \ Mass Spectrometry (HS-SPME\GC\MS) analysis were applied to EVOOs samples. Multivariate statistical analyses (PCA and Linear regression) were …
