| Summary: | Due to the expanding world's population and the associated rise in demand for food, the global food supply chain is under a lot of pressure to keep up with demand while preserving food quality, preventing waste, avoiding deforestation, and lowering carbon footprints (FSC). Due of speedy computational capabilities and the availability of data, block chain technology has emerged as a feasible strategy that might help create a safe and secure FSC. According to the large body of literature that has been written on this subject over the last several years, block chain has garnered significant interest among experts all over the globe. The authors of this paper want to illustrate the tremendous potential and usefulness of block chain in FSCs by reviewing and assessing the existing studies. This study provides a review of block chain's use in FSCs and discusses adoption issues such as scalability, interoperability, and high cost. Additionally, it offers several possible fixes for these issues. A bibliometric analysis is also provided to help scholars and practitioners understand the framework and current direction of this field's study. The study found that the majority of the research has focused on using block chain in finance, logistics, and product authenticity. Additionally, block chain is ready to take center stage as a technology for enhancing FSC traceability and transparency, reducing risk, and - most importantly - increasing trust between multiple stakeholders. © 2022 IEEE.
