Abstract Food supply chains are benefiting from blockchain technology, as it establishes a shared, secure record of information flows, thus reducing food safety risks, increasing consumers’ trust in products’ provenance and enhancing supply chain efficiency. However, despite some embryonic applications, systematic literature review reports very few investigation studies. This article proposes a potential design and update frequency of relevant data to be stored in the Ethereum blockchain for monitoring and traceability purposes and explores the cost connected to every transaction in the case of a fresh milk processing industry and supply chain, from dairy farms to the end consumers. Results show that (i) investments are limited for the supply chain actors; (ii) the benefits of a blockchain-enabled supply chain can be achieved with a minimal impact on the product’s consumer price, and (iii) the costs of operating the blockchain increases as we move down along the tiers of the supply chain.

估计区块链采用对食品加工业和供应链的影响

摘要 食品供应链正受益于区块链技术，因为它建立了一个共享、安全的信息流记录，从而降低了食品安全风险，增加了消费者对产品来源的信任，提高了供应链效率。然而，尽管有一些胚胎应用，系统文献综述报告的调查研究很少。本文提出了存储在以太坊区块链中的相关数据的潜在设计和更新频率，以用于监控和可追溯性目的，并探讨了在鲜奶加工业和供应链的情况下，从奶牛场到奶牛场的每笔交易的相关成本。最终消费者。结果表明：(i) 对供应链参与者的投资有限；
