Abstract

The aim of the study was to assess the influence of talc on the extra virgin olive oil volatile profile during storage. The obtained results showed that the volatile profile of the oil produced without talc addition was rich in C6 volatiles and poor in esters. The Principal Component Analysis discriminated 6-month stored oils, characterized by higher amount of auto-oxidation volatile compounds, from 3-month stored and fresh oils. The use of talc did not significantly influence the volatile profile of the examined oils during storage, with the exception of C6-LOX aldehydes that significantly decreased as a consequence of talc addition.
