A Bibliometric Analysis and Visualization of Research Trends in Green Extraction: A Novel Strategy for Anthocyanins Extraction Using Natural Deep Eutectic Solvents (NADES)

This article contributes to the bibliometric evaluation of the natural deep eutectic solvents and the study of the extraction of bioactive compounds, especially anthocyanins. Bibliometric analysis is the statistical analysis of published articles by researchers at a particular time and place, with the relation among these articles. The data were pre-processed and analyzed with the Vos Viewer and Bibliometrics, the professional mapping tools. 14 years of publication (from 2011 to 2024) were included in this evaluation process. VOS Viewer software has been used to classify the different keywords, according to their co-citation, following clustering techniques. Based on the results of a bibliometric analysis, from 2011 to 2024 have were 746 studies related to post-harvest extraction anthocyanins using natural deep eutectic solvents from ScienceDirect. From this study, it was found that research trends related to post-harvest natural deep eutectic solvents increased from 2011 until 2024. In this study, it was also found that the most natural deep eutectic solvents article publication titles in food chemistry. So natural deep eutectic solvents have a good impact on the use of solvents that can replace conventional organic solvents.
