Sažetak
Extra virgin olive oil is produced by mechanical and physical processes and therefore it keeps all valuable bioactive and aroma compounds. Fresh produced olive oil is always turbid and it has influence on the consumer’s choice. Filtration has recently imposes as last step in product finalization. During filtration, quantitative and qualitative changes take place, especially on minor components. The influence of filtration on phenolic content, α-tocopherol, oxidative stability and sensory attributes (oil aroma) of Oblica and Leccino olive oils were studied. Filtered oils of both investigated oils show a significant decrease on the total phenol content. In Oblica oil filtration had no effect on α-tocopherol content while in Leccino higher content of α-tocopherol was detected in unfiltered oil. After the filtration in both studied oils, oxidative stability loss was recorded of more than 14%. The filtration effect on oil aroma was evaluated by a panel tasters and sensory evaluation showed no significant influence on the sensory scores.
