食品安全快速检测技术的专利文献计量研究

目前，食品安全快速检测技术得到了飞速发展和广泛应用，也是食品安全领域的研究重点，但是对食品安全快速检测技术的专利文献情报研究几乎空白。本文基于德温特专利数据库和德温特专利分析平台对食品安全快速检测技术领域相关专利进行分析，客观揭示技术发展态势、分析主要原创技术的全球专利布局、挖掘前沿研究热点等；并通过分析在华专利，深度透视我国在食品安全快速检测技术领域实施技术创新所面临的国内外形势和存在的问题。我国为食品安全快速检测技术最大的专利申请国，但是我国专利授权比例有待提高。我国在专利布局战略方面倾向于本土专利布局。结合国际专利分类号分析出我国主要的专利技术领域集中在利用光学、单克隆抗体、核酸和遗传工程等方法和手段进行食品安全快速检测。本文还通过专利地图洞悉全球食品安全快速检测技术领域技术布局变迁及当前热点领域，为食品科研工作者提供参考。

Bibliometric Study of Patents on Rapid Food Safety Detection Technologies

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.
