Bibliometric Analysis and Literature Review of Ultrasound- Assisted Extraction

The challenges of the chemical industry to achieve green chemical products motivate strategies to increase strength, and safety, and reduce energy consumption, and cost. Ultrasound as a technique that is clean, efficient, inexpensive, and highly safe has become a research trend in extraction methods. Therefore, it is important to review research developments and trends in these emerging techniques. This article analyzes bibliometric ultrasound-assisted extraction data from the VOSviewer application. Bibliometric data was collected from 2021 to 2023 in a total of 1,312 articles. Research hotspots and future research directions are predicted through co-occurrence and co-authorship analysis. The featured category is Chemistry with 500 articles. The journal with the most dominant productivity is Ultrasonic Sonochemistry. China is ranked first in the article publication. The top author is Parag Gogatei. Collaboration is carried out between researchers, research groups, and countries. Ultrasound-assisted extraction has high efficiency so it can reduce process costs and achieve green chemistry. In addition, ultrasound is widely used to maintain essential oil content and has been tested for safety with low cytotoxicity. The use of solvents is used in the ultrasound-assisted extraction process to increase process efficiency. In the last stage, ultrasound-assisted extraction became a research hotspot.
