Oil extraction research on scopus from 2016 to 2024, a bibliometric overview

Concerns about sustainable food production, renewable energy, and environmental preservation have made vegetable oil extraction technology more and more significant. 235 publications were obtained from the Scopus database using keywords like “vegetable oil extraction,” “solvent extraction,” “green extraction,” and “biosolvent.” This study provides a bibliometric overview of research on vegetable oil extraction from 2016 to 2024. China contributed 50.6% of the 87% growth in research production, followed by the USA, Brazil, Italy, and Spain. Zhejiang University, Indian Institute of Technology, and Islamic Azad University were the most productive universities. With 53 publications, Food Chemistry was the most popular journal. Journal of Chromatography A came in second with 24 and Journal of Oleo Science third with 15. Additional noteworthy journals were Food Analytical Methods (8), Molecules and Talanta (9 each), Journal of Separation Science (10), and Ultrasonics Sonochemistry (13). Supercritical CO₂, ultrasound, and microwave-assisted extraction are examples of advanced techniques that are being used more and more in conjunction with traditional methods. These techniques preserve over 85% of bioactive compounds, improve yields by 15–40%, and use less solvent by 30–50%. The data demonstrates a global trend toward the production of high-quality, ecological, and energy-efficient vegetable oils.
