Abstract

Green extraction techniques have emerged as sustainable alternatives to conventional extraction methods, addressing environmental concerns and improving the efficiency of recovering bioactive compounds from natural sources. This review provides a comprehensive overview of major green extraction methods including supercritical fluid extraction (SFE), microwave-assisted extraction (MAE), ultrasound-assisted extraction (UAE), pressurized liquid extraction (PLE), enzyme-assisted extraction (EAE), and the use of green solvents such as deep eutectic solvents (DES). The principles, advantages, limitations, and industrial applications of each technique are discussed. A comparative analysis highlights the energy efficiency, environmental impact, and economic viability of these approaches. Finally, challenges and future directions are outlined to guide research and industrial adoption toward sustainable extraction processes.

Keywords: The principles, advantages, limitations, and industrial applications of each technique are discussed.
