The research was carried out during the 2014/2015 harvest period.

During 12 months of storage, changes in free fatty acid composition and peroxide values, UV absorption values, total phenol content, phenolic and tocopherol profiles of filtered (F) and unfiltered (UF) samples were monitored monthly. The results showed that both F and UF olive oil samples were classified as EVOO according to International Olive Council (IOC) standards. Although UF olive oil has higher total phenols…
