Bibliometric Mapping of Rambutan (Nephelium lappaceum L.) Research: Trends and Directions
Article Sidebar
Main Article Content
Abstract
This study presents a comprehensive bibliometric analysis of 551 journal articles retrieved from the Web of Science (WoS) database to evaluate the biological and pharmacological potential of rambutan (Nephelium lappaceum L.). Using co-citation and co-word analyses, the research identifies key thematic clusters and emerging trends. Bibliographic mapping highlights four dominant themes: (1) valorization of rambutan byproducts, (2) its role as a functional food source, (3) investigation of different plant parts for diverse applications, and (4) utilization of rambutan peel in nanomaterial synthesis. Co-word analysis further emphasizes four critical research directions: (i) applications of rambutan-derived compounds, (ii) biological activities of their constituents, (iii) sustainable extraction and production methods, and (iv) fruit waste valorization for environmental sustainability. Overall, the findings provide a holistic understanding of rambutan’s multifaceted significance across food science, pharmacology, and environmental domains. The study also identifies existing research gaps and future opportunities, offering valuable insights into advancing both scientific inquiry and industrial applications.
