Abstract
This study introduces an innovative approach, Ultrasonic Sonication Pretreatment Sparger-based Microwave Assisted Extraction (U Sp-MAE), designed to enhance lemongrass essential oil extraction. Addressing the challenge of maximizing yield and quality, our work systematically optimized key extraction parameters. Results demonstrated a significant improvement over conventional methods, with the highest yield of 1.89% achieved under specific conditions: a Sparger Flow rate of 4 L/min, Ultrasound Power of 700 W, Sonication Time of 5 min, and Liquid-to-Solid Ratio of 5 mL/g. This method not only advances essential oil extraction but holds promise for broader applications in society, showcasing its potential impact on sustainable and efficient resource utilization.
