Abstract: To further understand the global status and current trends of the research on anaerobic digestion of food waste， the Web of Science citation database was used. The food waste anaerobic digestion was taken as the subject search terms， and the relevant literature collected in this database from 1994 to 2018 was analyzed quantitatively. The results indicated that in the statistical time range， China was in the top of the list of published articles and the number of published papers was the fastest growth. Among the research institutes， Tsinghua University， Chinese Academy of Sciences， and Tongji University ranked top three in terms of their total publications. Environmental Sciences & Ecology， Engineering and Energy & Fuels were the main fields which had the largest amount of publications of food waste anaerobic digestion. Through the analysis of key words， methane production， co-digestion， microbial community， volatile fatty acids， life cycle assessment and pretreatment would be continued to become research hotspots in the future research.
