Blockchain Application in Food Supply Chains: Bibliometric Analysis and Future Research

This study aimed to organize and analyze studies on blockchain application in food supply chains and to discover emerging research themes and topics using cluster analysis to determine future research directions. Bibliometric analysis was used to organize and analyze the literature on blockchain application in food supply chains. The database consisted of 629 Scopus-indexed articles from 2016 to 2021. These were organized using bibliometric analysis (e.g., annual publication trends) and content analysis (e.g., research method applied). Themes and emerging research trends were then clustered based on keywords using the VOSviewer software. The analysis showed that manufacturing is the type of industry that most applies the blockchain. Trust is the most-cited benefit achieved by blockchain application, while traceability is the most-claimed function. Keyword classification resulted in seven main clusters (e.g., sustainability and transparency) and each cluster had emerging research trends (e.g., resilience toward sustainability and transparency). This research provides an overview of scientific development and emerging application trends related to blockchain application in food supply chains.
