Abstract
INTRODUCTION Extra virgin olive oil (EVOO), extracted from healthy olive fruits by mechanical procedure, has extraordinary health benefits in preventing chronic disease. The meta‐analysis studies of the Mediterranean diet and [...]
: This study investigated the physicochemical properties and polyphenol composition of extra virgin olive oils (EVOOs) extracted from three olive cultivars. The investigated cultivars were Arbequina, Koroneiki, and Manzanilla, grown in Olive Research Station in Rudbar county, Gilan province, Iran, at three ripening stages. Several parameters were analyzed, including peroxide and acidity values, unsaponifiable matter, oxidative stability, total aliphatic alcohols, fatty acids (FAs), sterols, and triacylglycerol composition. The results showed that as maturity increased, parameters such as oil content, acidity value, and iodine value, rise, while parameters including peroxide value, oxidative stability, aliphatic alcohols, and unsaponifiable matter decreased (p .05). The MUFA/PUFA ratio and total sterol content declined during the olive ripening stages (p
