Research Trends of Microplastic in Food in China based on Social Network Analysis
Abstract
(SNA) based on academic literature published in the past 10 years. The research focused on papers related to microplastics
in food published between June 2013 and June 2023, using the search terms “microplastics” and “food”. Keyword frequency
analysis, node degree analysis, and SNA were used. The results showed that degree centrality of “microplastics”, “pollution”,
“toxicity”, “source and distribution” and “ecological effect” were above 0.700, indicating that over 70% of the existing
Chinese papers on microplastics are focused on the pollution and toxic effects of microplastics on the ecosystem, which is
currently the main research direction, providing reference value for improving China's food safety status and decision-making.
