Background: Food and pharmaceutical supply chains face similar issues, such as product counterfeits allowing low-quality products to enter the market and supply chain inefficiencies. Applying blockchain technology could increase transparency and efficiency in the supply chains. However, the technology is still relatively young and, thus, has barely been implemented. Scope and Approach: This work aims to provide an overview of blockchain applications in food and pharmaceutical supply chains. Following the PRISMA method, the systematic literature review analyzes 78 applications in 74 publications. Deriving from the results, a general framework for blockchain applications in food and pharmaceutical supply chains is proposed, which should support practitioners in implementing blockchains and researchers in identifying research challenges. Key Findings and Conclusions: The literature review reveals that permissioned and private blockchain networks are most commonly applied, using Ethereum and Hyperledger Fabric as leading platforms. Many applications stored data off the blockchain and implemented different techniques to restrict access to confidential data. Smart contracts are crucial for improving supply chain management as they enable automatization. The general framework recommends a permissioned consortium network using the Hyperledger Fabric platform and Proof-of-Authority consensus protocol for supply chains. Challenges like regulations, standardization, and infrastructure must be solved to foster technology adoption in operations. • Review of blockchain technology applied in food and pharmaceutical supply chains. • Following a structure literature review, we reviewed 78 applications in detail. • Permissioned and private blockchain networks are applied most. • We propose a framework to foster blockchain implementation in these supply chains. • Challenges like regulations, standardization, and infrastructure as current hurdles.
