Global research trends on avocado oil and its fatty acid composition: A bibliometric review

The high content of unsaturated fatty acids in avocado oil (Persea americana) has prompted in-depth exploration across research subjects. This study uses bibliometric analysis to assess global research trends on avocado oil and its fatty acid composition from 2004 to 2024. The search string retrieved 255 articles from the Scopus database and then analyzed using R BibliometriX and VOSviewer software. These tools analyze descriptive structures and collaborative patterns and create network data maps. For comparison, we separated the data into two research periods, namely 2004e2013 and 2014e2024. There was a significant increase in the number of publications, with research focuses expanding from fundamental analysis of the chemical composition of avocado oil to practical applications such as adulteration detection and therapeutic use. An increase was also seen in the number of international collaborations, authors, countries, sources, affiliations, and diversification of research topics with Latin American and European countries as the main contributors. However, there are gaps related to the variability of fatty acid composition across cultivars and long-term health effects. This study provides in-depth insights into the evolution of avocado oil research to improve the quality of life of the global population. © 2025 Taiwan Food and Drug Administration.
