Abstract

Squalene (SQ) is an intermediate hydrocarbon in the biosynthesis of phytosterols and terpenes in plants. It is widely used for applications such as skin moisturizers, vaccines, or in carriers for active lipophilic molecules. It has commonly been obtained from sharks, but restrictions on their use have created a need to find alternative sources. We present a review of studies concerning SQ in olive groves to characterize its content and to provide new aspects that may increase the circular economy of the olive tree. There is a large variation in SQ content in virgin olive oil due to cultivars and agronomic issues such as region, climate, types of soil, crop practices, and harvest date. Cultivars with the highest SQ content in their virgin olive oil were ‘Nocellara de Belice’, ‘Drobnica’, ‘Souri’, and ‘Oblica’. An interaction between cultivar and aspects such as irrigation practices or agricultural season is frequently observed. Likewise, the production of high SQ content needs precise control of fruit maturation. Leaves represent an interesting source, if its extraction and yield compensate for the expenses of their disposal. Supercritical carbon dioxide extraction from olive oil deodorizer distillates offers an opportunity to obtain high-purity SQ from this derivative. Exploiting SQ obtained from olive groves for the pharmaceutical or cosmetic industries poses new challenges and opportunities to add value and recycle by-products. © 2019 Society of Chemical Industry. © 2019 Society of Chemical Industry

Quality index

Bibliometric impact. Analysis of the contribution and dissemination channel

The work has been published in the journal Journal Of The Science Of Food And Agriculture due to its progression and the good impact it has achieved in recent years, according to the agency WoS (JCR), it has become a reference in its field. In the year of publication of the work, 2020, it was in position 8/57, thus managing to position itself as a Q1 (Primer Cuartil), in the category Agriculture, Multidisciplinary.

From a relative perspective, and based on the normalized impact indicator calculated from World Citations from Scopus Elsevier, it yields a value for the Field-Weighted Citation Impact from the Scopus agency: 1.71, which indicates that, compared to works in the same discipline and in the same year of publication, it ranks as a work cited above average. (source consulted: ESI Nov 14, 2024)

This information is reinforced by other indicators of the same type, which, although dynamic over time and dependent on the set of average global citations at the time of their calculation, consistently position the work at some point among the top 50% most cited in its field:

  • Field Citation Ratio (FCR) from Dimensions: 6.7 (source consulted: Dimensions Sep 2025)

Specifically, and according to different indexing agencies, this work has accumulated citations as of 2025-09-18, the following number of citations:

  • Scopus: 27
  • Europe PMC: 1

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2025-09-18:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 79.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 78 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 0.5.
  • The number of mentions on the social network Facebook: 1 (Altmetric).
  • The number of mentions on the social network X (formerly Twitter): 1 (Altmetric).
