Efficient and reliable management of the business operations within the food supply chain is crucial to ensure the quality, safety, traceability, and security of food products. Streamlining different food supply chain management operations by utilizing cutting-edge technologies such as Cloud computing and the Internet of Things (IoT) has gained enough attention in recent years. Most of the systems developed for streamlining food supply chain management operations are centralized and offer limited traceability, reliability, transparency, immutability, provenance, and consumer trust in food products. Furthermore, such systems are prone to single-point failure, as well as data tampering and alteration. Blockchain is a decentralized technology that follows a distributed peer-to-peer (P2P) architecture for storing and processing data. It offers several benefits to participants of the food supply chain in terms of improved data provenance, transparency, traceability, security, and immutability. This article discusses blockchain technology’s potential role and opportunities in transforming food supply chain processes. It identifies and discusses key requirements of food supply chain participants that blockchain technology must meet to efficiently manage the business processes involved in the food supply chain. It explores case studies and research projects in the food sector that are based on blockchain technology, aiming to highlight the applicability of blockchain in the food supply chain. Finally, it identifies and discusses open research issues and challenges in the food industry.

Purpose: The purpose of this research is to study and analyze the literature that integrates Lean Six Sigma (LSS) approach with blockchain technology in different sectors for improved quality management.Design/methodology/approach: This study presents a scoping review on the application of integrated LSS and blockchain technology in the manufacturing and healthcare sector. Further, the authors examined existing blockchain-based solutions on a variety of dimensions, including application area, technical approach, methodology, application scenario, various blockchain platforms, purpose, and monitoring parameters. The authors study LSS approaches in detail, as well as the key benefits that blockchain technology can enable. Finally, the authors discuss significant research problems to be addressed in order to develop a highly efficient, resilient, and secure quality management framework using blockchain technology.Findings: It has been observed that the adoption of blockchain technology for quality management and assurance is influenced by several factors such as transaction execution speed, throughput, latency. Also, prior blockchain-based solutions have neglected to leverage the benefits of LSS methodologies for effective quality management.Originality/value: This is the first study to explores the influence of blockchain technology on quality management and assurance in manufacturing and healthcare industry. Furthermore, prior research has not examined how integrating the LSS methodology with blockchain technology can aid in the control of product quality management.
