Optimization of pectin extraction using response surface methodology: A bibliometric analysis

In this study, 209 articles have been surveyed on the Pectin Extraction via Response Surface Methodology (RSM) that have been collected from Web of Science(C) and Scopus(C), and analyzed by using Bibliometrix, an RStudio package for science mapping analysis. Trends in the optimization and extraction methods of pectin via RSM have been pointed out, which may be useful for further research. Results shown that publications on Pectin Extraction via RSM have started for more than 20 years, with a growing trend, more than triplicating in the last 10 years. Based on such set of papers, China has been the most active country in local productions, whereas Iran, Brazil, India, and the United Kingdom have contributed with international-wide collaborative publications in optimization pectin extraction through RSM. Assisted extraction categories, physical and functional properties of pectin have taken on more relevance by 2012, especially with consolidation of microwave-assisted and ultrasound-assisted extraction techniques.

Automated summary

This study analyzed 209 articles on pectin extraction via response surface methodology (RSM) collected from Web of Science(C) and Scopus(C), using Bibliometrix for science mapping analysis. The trends in optimization and extraction methods of pectin via RSM were identified. The results showed that China was the most active country in terms of local productions, while Iran, Brazil, India, and the United Kingdom contributed to international collaborative publications.
