This study examines the effect of blockchain adoption on the agri-food supply chain. A systematic literature review approach was used to analyze and synthesize the findings from the existing literature, focusing on fundamental research themes, research gaps, and the direction of future research on the impact of blockchain adoption in the agri-food supply chain. Twenty-seven full-length articles were considered and thematically analyzed in this study. The authors identified eight themes from the literature, including factors responsible for blockchain adoption and new research areas such as digitalization and the impact after adoption. These themes shed light on the agri-food supply chain practices following the adoption of blockchain technology. Moreover, this study provides a foundation for strategic and policy initiatives in the agri-food industry involving blockchain technology. The findings indicate that critical factors driving blockchain technology adoption in the agri-food industry include ensuring food traceability and transparency, food safety and security, food supply and logistics, food integrity, environmental awareness, and reducing food waste. Additionally, this study highlights the importance of guidelines and policy-level involvement after adopting blockchain technology, particularly in facilitating accurate quantification and promoting digitalization to address challenges and streamline processes. The study concludes by suggesting future research avenues for blockchain technology in the supply chain domain.
