Abstract

Aiming to grasp the progress and hotspots of theaflavin research and objectively reflect the influence of different countries, authors, research institutions and journals in this field, bibliometrics and CiteSpace.5.7.R5W visualization analysis software were used in this study to analyze 725 and 391 Theaflavin/Theaflavins (TF/TFs) literatures collected by Web of Science (WOS) and China National Knowledge Infrastructure (CNKI) from 1964 to 2021. It was found that China, India, the United States and Japan were the countries with the most research on theaflavin. Tanaka of Nagasaki University in Japan had the most researches. The catechin oxidation products related to theaflavins had been reported the most. Liu Zhonghua, Jiang Heyuan and Tu Youying were the leaders of theaflavins research in China. Food Science Technology and Journal of Tea Science were the English and Chinese journals with the highest publication volume of theaflavin. Keyword analysis showed that Chinese literature mainly focused on the preparation and separation of theaflavins and their effects on the quality of black tea. English literature focused on the pharmacological research of theaflavins, and the preparation and pharmacological effects of theaflavins were still the research hotspots in the future.
