Abstract:
Background: Essential oils are utilized in various food applications and are a rich source
of naturally occurring volatile components. The extraction of essential oils has used conventional
techniques for several years, but these methods require a long duration of time, more solvent, and
high energy. However, recent advancements have led to novel and eco-friendly techniques that significantly
enhance the essential oil yield while minimizing the use of resources.
Method: This study describes the recent research on the extraction of essential oils and their components,
focusing on microwave-assisted extraction (MAE) and ultrasound-assisted extraction (UAE).
Result: This review explores the instrumentation, mechanism, and applications behind MAE and
UAE. It also describes the emerging technologies for the extraction of essential oils, along with their
optimized conditions.
Conclusion: These techniques represent a more sustainable and efficient approach for the extraction
of essential oil from various plant sources, aligning with the principles of green chemistry.
