Abstract

The food industry is increasingly focused on ensuring food safety and meeting consumer demands for transparency regarding food origins and production methods. Traditional centralized systems for supply chain traceability face challenges related to trust, transparency, and scalability, which are exacerbated by the complexity of global supply chains. Blockchain technology offers a promising solution by providing a decentralized, secure, and transparent system for tracking food products from farm to fork. This paper reviews the literature on blockchain technology and its application in food supply chains, highlighting key features, benefits, challenges, and case studies of successful implementations. We propose that blockchain can significantly enhance food safety by improving traceability, reducing fraud, and increasing consumer trust. However, challenges such as data privacy, security concerns, and technological limitations must be addressed. Future research directions are also discussed to further explore the potential of blockchain in ensuring food safety.
