✦ Synopsis

AhtraCt

The effect of climate on the chemical composition of virgin olive oil has received scant attention. In this work, the relationship between chemical composition and altitude, the latter being an indirect parameter related to climate and soil, was studied. Two altitudes, valley (< 400 m) and mountains (> 700 m) were studied; 126 samples of virgin olive oil were characterized by 53 compounds and it was found that sterols and some triterpenic alcohols and hydrocarbons changed systematically with altitude. Two linear discriminant equations, with correct classifications greater than 90%, were obtained and verified with samples of another crop. Similar results were obtained.

This investigation examines the effect of freezing olives (–18β€…Β°C) before processing into oil on the transfer of the phenolic compounds i

## Abstract Cross‐flow microfiltration (MF) and ultrafiltration (UF) with different commercial membranes were applied to virgin olive oil (VOO) in order to remove some compounds that are responsible for oil unpleasant flavor without altering the oil composition. Experimental tests were carried out
