Abstract:

This study presents an analysis of the research of purple corn anthocyanins based on 217 relevant literature from the Web of Science core collection from 1997 to 2023. The data was visualized using CiteSpace software to explore the annual publication trends, keywords, countries/regions, and institutions. The findings indicate a significant increase in the number of publications in the field of purple corn anthocyanins. The main research topics in this field include the functional activities, chemical composition, stability, and extraction methods of purple corn anthocyanins. The current research frontiers in this field encompass four aspects: the effect of purple corn on reducing or preventing diseases, the new extraction technology, the stability of anthocyanins and the application of animal husbandry. The top five research institutions in this field are from the United States, China and Thailand. The United States focuses on traditional research areas such as functional activities, stability, and extraction process, while China and Thailand concentrate on the emerging field of applied research in animal husbandry. The application of purple corn anthocyanins in livestock farming may become a future research focus.
