Olive Oil Processing: Current Knowledge, Literature Gaps, and Future Perspectives

Abstract Olive oil quality is determined through a series of steps starting from the olive oil tree and ending to the consumer. Among these steps, olive oil processing plays a decisive role in determining quality. This work reviews current olive oil‐processing technology and compares available technologies for the unit operations involved. Furthermore, for each unit operation involved in olive oil processing, the effect of process variables on the parameters determining olive oil quality is presented and discussed. Process efficiency and environmental impact are also presented and discussed for specific unit operations. Through this review, the gaps in current knowledge are highlighted. Finally, future perspectives on olive oil processing and further research required for olive oil quality optimization are presented.
