Abstract
Introduction of a two phase extraction system for olive oil was supposed to improve the waste extraction.
The contribution of the second centrifugation of the two phases system was analyzed on a fresh crop of olive fruits in 1995/96.

Comparative analyses of the oil content of twenty nine decanter samples were done on first centrifugation pastes (from Picual var.) that were immediately centrifuged again by a two way decanter.

The oil recovered from this second step was approximately 1/3 of the amount of oil recovered after the centrifugation of the paste.

Seven oil samples were collected after first and second centrifugation and their physicochemical characteristics were determined (Acidity, K270, Sterols, Polyphenols Content, Carotenoids, Erythrodiol, Waxes, Aliphatic Alcohols and Fe content) high correlation between the values of these parameters and the second centrifugation were found.
