While taste and price remain top priorities, more consumers are starting to consider the safety and sustainability of ingredients when dining out—a challenge that restaurants are working to address.
To support this shift, researchers at the University of Missouri are investigating how a revolutionary technology that could allow consumers to track ingredients all along the supply chain will affect their decision-making processes.
“Customers have become increasingly concerned about where their food is coming from, whether it’s sustainably sourced and how safe it is to eat,” Pei Liu, an associate professor of hospitality management in the College of Agriculture, Food and Natural Resources, said.
Many diners find it difficult to verify that information because restaurants rarely publicize how their food is sourced in a clear or consistent way. This lack of information breeds uncertainty for the customers. But Liu and her team have found a potential solution: blockchain.
Blockchain uses a decentralized, secure and transparent method of recording transactions across multiple computers. Once validated, each transaction is cryptographically linked to the one before it, making the data extremely resistant to tampering or unauthorized changes. This immutability helps promote trust and transparency in shared systems.
When restaurants use blockchain to give consumers greater visibility into their supply chains—a practice known as food traceability—it builds trust in sustainable foods, researchers found. That trust not only enhances the overall dining experience but also strengthens the restaurant’s reputation. In fact, the study found that consumers are more willing to pay premium prices when blockchain transparency reduces their concerns about food safety. Because food safety was the most influential factor in their decision making, this increased confidence could ultimately boost restaurant revenue.
