Abstract
The authenticity and traceability of olive oils have been a growing concern over the past decades, generating numerous scientific studies. This article applies the tools of bibliometric analyses to explore the evolution and strategic orientation of the research focused on olive oil geographical and varietal origins. A corpus of 732 papers published in 178 different journals between 1991 and 2018 was considered. The most productive journals, authors and countries are highlighted, as well as the most cited articles associated with specific analytical techniques. A cluster analysis on the keywords generates 8 main themes of research, each focused on different analytical techniques or compounds of interest. A network between these thematic clusters and the main authors indicates their area of expertise. The metabolomics methods are drawing increasing interest and studies focused on the relationships between the origin and the sensory or nutritional properties provided by minor compounds of olive oils appear to be future lines of research.
Highlights
Olive oils and their composition in relation to their geographic or varietal origins have been extensively studied in recent years, as part of the food authenticity topic
A significant number of articles mention the use of chemometrics modeling or target particular compounds of olive oils that could be markers of their origin
Some articles employ general keywords indicating their interest in olive oil authenticity, traceability or quality, while other publications specify whether they focus on geographical or varietal origins
Summary
Olive oils and their composition in relation to their geographic or varietal origins have been extensively studied in recent years, as part of the food authenticity topic. In the case of olive oil, European regulation requires the geographical origin (EU member state or third country) and quality grade (extra virgin, virgin, blend of refined and virgin or pomace oil) to be specified on the label [3]. Additional information such as a protected designation of origin (PDO) or geographical indication (PGI) can be present. As explained in previous bibliometric studies, the exploration of the structure of a research field can provide strategic
