The global food supply chain is a complex network involving various stakeholders, from farmers and producers to distributors and consumers. Ensuring transparency, traceability, and food safety has become a paramount concern in the wake of numerous foodborne illnesses and counterfeit products. Blockchain technology has emerged as a promising solution to address these challenges by enabling a decentralized and immutable ledger system. This review paper provides a comprehensive analysis of the applications of blockchain technology in the food supply chain. It synthesizes the existing literature, surveys, and case studies to explore the potential of blockchain in enhancing food traceability, reducing fraud, improving supply chain efficiency, and empowering consumers. Moreover, the paper evaluates the challenges and limitations associated with the implementation of blockchain in the food supply chain, including data privacy, scalability, interoperability, and regulatory frameworks. It also discusses strategies used to provide security in blockchain technology and future directions in blockchain technology for the food industry. The paper begins by introducing the fundamental concepts of blockchain and its relevance to the food industry. It then examines the key features of blockchain technology, such as immutability, transparency, and decentralization, and their implications for the food supply chain. The review further delves into various blockchain-based solutions and platforms developed specifically for food traceability, supply chain management, and quality assurance. By synthesizing the existing knowledge and providing critical insights, this review paper contributes to a better understanding of the transformative potential of blockchain technology in the food supply chain. It serves as a valuable resource for researchers, practitioners, policymakers, and industry stakeholders seeking to leverage blockchain to create a safer, more transparent, and efficient food system.
