Analysis of research status and trend of food safety standards based on bibliometrics and knowledge graph in China

Abstract

ObjectiveTo analyze the current situation and development trend of food safety standards research in China from a bibliometric perspective.MethodsA total of 1 727 related articles from China National Knowledge Infrastructure were retrieved， screened， and analyzed based on institutions， authors， funds， journals， and keywords. VOSviewer and CiteSpace software were used to conduct a multidimensional knowledge graph visualization and metrological analysis of food safety standards related articles in China.ResultsChina’s food safety standards research had generally shown a growth trend， having gone through three stages of development： A start-up period， a period of rapid development， and a period of fluctuating development from 1993 to 2021. Food safety standards research was concentrated in three institutions： the National Center for Food Safety Risk Assessment （CFSA）， the Chinese Academy of Agricultural Sciences， and Renmin University of China. There were four major author networks， mainly represented by researchers from the CFSA. The first source of literature on food standards was the Chinese Journal of Food Hygiene， with 103 articles， accounting for 5.96% of the total number of articles published. The most frequent keywords were food additives （91 times）， national food safety standards （85 times） and food safety law （66 times）， forming 8 categories of research themes， which mainly centered on food safety standards. Keyword analysis revealed that hot topics of research emerging from 2016 to 2021 included tracking and evaluation， vitamins， nutrients， heavy metals， physical and chemical indicators， food labeling， and national standards.ConclusionThis study provides a reference for understanding the overall research status and development trend in the field of food safety standards in China.
