In this first study on the potential use of a phenolic extract
recovered from a by-product of the olive oil process, gave interesting
results. In fact, PE showed it was capable of preserving the
a-tocopherol content and reducing the production of negative volatile
compounds in a refined olive oil during a simulated frying
process; furthermore, the residual concentration of polyphenols
in the oil after twelve hours of experimentation depended on their
initial content.
