| dc.description.abstract | This dissertation aims to provide a state-of-the-art overview of blockchain’s ability to enhance traceability and transparency. It focuses on combating food fraud and identifying the key barriers to its widespread adoption in the food supply chain. The review applies a qualitative approach, utilizing a systematic literature review methodology to address two research questions: “How can blockchain technology enhance transparency and traceability in the food supply chain to combat food fraud?” and “What are the key barriers to adopting blockchain technology in the food supply chain?". This SLR collected data from Web of Science and Scopus, yielding 96 publications based on keywords such as "blockchain," "distributed ledger," "food fraud," "food supply chain," "transparency," and "traceability." Following PRISMA 2020 guidelines and predefined inclusion and exclusion criteria, along with minimum quality assessment criteria, a final sample of 36 publications was included in the review. Thematic analysis and the Technological-Organizational-Environmental framework were employed to synthesize the data. The findings revealed that blockchain technology, as a decentralized, immutable, and distributed ledger system, provides a better traceability system and enhances transparency in the food supply chain compared to traditional systems with centralized databases. They are often vulnerable to single points of failure and information asymmetry due to centralized databases. Additionally, the review identified 14 barriers to its widespread adoption, spanning technological, organizational, and environmental dimensions. Overall, blockchain technology can significantly increase supply chain transparency, mitigating food fraud by facilitating better information flow among stakeholders. It enables a more robust traceability system that goes beyond the current EU Reg. 178/2002 "one step forward, one step backward" approach. As this review focuses on the state of the art of blockchain technology in the food supply chain to combat food fraud, to the best of the author's knowledge, it is one of the few studies that examine blockchain’s advancements in this domain. The insights from this dissertation apply to other industries and can be harnessed by researchers and industry stakeholders to develop a more efficient and resilient food supply chain, as well as inform and elevate purchase decisions among consumers. | pt_PT |
