该文基于文献计量学,应用VOSviewer 1。6。20软件,对1990-2023年中国知网(CNKI)数据库、Web of Science(WOS)数据库中辐照杀菌在食品科学领域141篇中文文献和1 337篇英文文献进行计量统计和可视化分析,并借助专利搜索工具SooPAT及商业查询平台天眼查对辐照杀菌专利申请状况及企业发展现状进行分析。结果表明,辐照杀菌领域发文量自2000年后基本呈逐年上升趋势;美国、中国、英国为主要发文国家;《核农学报》、《Applied and Environmental Microbiology》发文量较多;中国国家自然科学基金为扶持力度最大的基金项目;中文核心作者朱佳廷、冯敏、刘春泉之间联系紧密,WOS数据库发文量最多的作者为THAYER DW;关键词共现分析发现辐照剂量及辐照杀菌应用是研究热点。辐照杀菌领域的申请、发明专利分别为1 997件、1 367件;目前国内现存辐照杀菌相关公司23家。
Research progress and industry development status of irradiation sterilization based on bibliometrics
Based on bibliometrics and VOSviewer 1.6.20 software,metrological statistics and visual analysis of 141 Chinese and 1 337 English documents on radiation sterilization in the field of food science in China Knowledge Network(CNKI)and Web of Science(WOS)databases from 1990-2023 were carried out,and the status of irradiation sterilization patent applications and the development status of enterprises were analyzed by means of the patent search tool SooPAT and commercial search platform Tianyecha.The results showed that the number of published articles in the field of radia-tion sterilization had been increasing year by year since 2000,and the United States,China,and the United Kingdom were the main issuing countries.The Journal of Nuclear Agricultural Sciences and Journal of Nuclear Agriculture and Applied and Environmental Microbiology had more published articles,and the National Natural Science Foundation of China was the most supportive fund project.The Chinese core authors ZHU J T,FENG M and LIU C Q were closely connected with each other,and the author with the most publications in WOS database was THAYER D W.The co-occur-rence analysis of keywords found that irradiation dosage and the application of radiation sterilization were the research hotspots.The number of appli-cations and invention patents in the field of radiation sterilisation were 1 997 and 1 367 respectively.At present,there are 23 radiation sterilisation re-lated companies existing in China.
