Coffee and geographical indication in food science perspective: a bibliometric analysis for future research

Abstract

This study aimed to analyze the scope of geographical indication (GI) coffee using bibliometric review. A bibliometric approach was applied using data from 292 documents published between 2003 and 2024 using keywords coffee AND geographical AND indication OR origin. The analysis was conducted through Bibliometrix R package, VOSviewer, and Microsoft Excel 365, retrieving data from the Scopus database in October 2024. The results showed that interest in GI coffee grew from 2016, increased significantly in 2022 with over 40 publications. The research field of the top ten journals was mostly in the fields of food science and technology, with Food Chemistry as a top journal. Among all countries, Italy contributed to the most publications, meanwhile the most institutions contributor was the Slovak University of Agriculture in Nitra. Recent studies have increasingly focused on chemometrics, adulteration, and food quality. This review certainly serves as a reference for further research on GI coffee. This review certainly can provide a reference point for further research related to GI coffee.
