Abstract: Rapid food safety detection technologies have currently seen rapid development and wide applications and have become a research priority. However, there is a lacuna of bibliometric studies on rapid food safety detection technologies in the literature. This article presents an analysis of patents on rapid food safety detection technologies based on the Derwent Innovations Index Database and the Derwent Innovation Patent Analysis Platform with the aim of revealing the technology trends, understanding the worldwide patent portfolio of the main original technologies and finding hot topics of frontier research. Also, this article provides insights into the domestic and international situation China faces in implementing technical innovations for rapid food safety detection and existing problems in this area. China is the world’s largest applicant for patents on rapid detection food safety technologies, but the proportion of patent grants in the country still needs to be improved. There is a trend that Chinese inventors prefer to apply for patents in their own country. According to the international patent classification number, the major technical fields in China are focused on the use of optical methods, monoclonal antibody, nucleic acid and genetic engineering for rapid food safety detection. Through the patent map, this article provides a thorough understanding of the technical layout change of rapid food safety detection worldwide and the current hot topics, which will provide useful information for food researchers.
