Food safety has emerged as the topmost priority in the current fast-paced food industry era. According to the World Health Organization, around 600 million people, approximately 1 in 10 individuals worldwide, experience illness due to contaminated food consumption, resulting in nearly 0.42 million fatalities annually. The recent development in software and hardware sectors has created opportunities to improve the safety concerns in the food supply chain. The objective of this review is to explain the fundamentals of blockchain and its integration into the supply chain of various food commodities to enhance food safety. This paper presents the analysis of 31 conceptual works, 10 implementation works, 39 case studies, and other investigations in blockchain-based food supply chain from a total of 80 published papers. In this paper, the significance of adapting conceptual ideas into practical applications for effectively tracing food commodities throughout the supply chain has been discussed. This paper also describes the transformative role of blockchain platforms in the food industry, providing a decentralized and transparent ledger to access real-time and immutable records of a product's journey. In addition, both the positive impacts and challenges associated with implementing blockchain technology in the food supply chain have been evaluated. In summary, the blockchain-based food supply chains offer greater transparency, traceability, and trust, ultimately resulting in higher standards of food safety and quality.
食品安全已成为当前快节奏食品工业时代的首要关注点。世界卫生组织的数据显示，全球约有 6 亿人，即约十分之一的人因食用受污染的食物而患病，每年导致近 42 万人死亡。软件和硬件领域的最新发展为改善食品供应链中的安全问题创造了机会。本次综述的目的是解释区块链的基本原理及其在各种食品商品供应链中的整合，以提高食品安全。本文从已发表的 80 篇论文中，分析了 31 篇概念性工作、10 篇实施性工作、39 个案例研究和其他关于基于区块链的食品供应链的研究。本文讨论了将概念性理念应用于实际应用中的重要性，以有效地追踪整个供应链中的食品商品。本文还介绍了区块链平台在食品行业中的变革性作用，为产品的旅程提供了一个去中心化和透明的账本，以访问实时和不可变的记录。此外，还评估了在食品供应链中实施区块链技术的积极影响和挑战。总之，基于区块链的食品供应链提供了更高的透明度、可追溯性和信任度，最终实现了更高的食品安全和质量标准。
