Abstract: Purpose/Significance During traceability in food supply chains, there exist lots of problems like the difficulty to share and exchange information with each other, non-standardization of the process and standards. Blockchain can provide the technical application guarantee for traceability in food supply chains based on its technology properties. Design/Methodology The samples for reference are selected in Web of Science and CNKI. The software of Citespace6.1R6, the hot issues and development trends in food supply chains using blockchain technology. Further, the current reviews of the references are given from three dimensions about solving the defects of traditional traceability, the design of tracing process and performance evaluations by application of blockchain technology. Conclusions/Findings The relative researches on this field are at the initial stage of development, and all papers are paid more attentions to the establishment of theory frame and case explorations. There are few results about the empirical tests to the specific cases and the deep analysis of theory.
