Lemongrass essential oil micro‐ and nanoencapsulation for industrial application: Production techniques and potential applications

Abstract Due to its characteristic aroma and diverse therapeutic properties, lemongrass essential oil (LEO) has garnered increased attention in the pharmaceutical, food, and cosmetic industries. However, LEO's volatile nature, low chemical stability, and limited solubility in water limits its applications in the industry. Micro‐ and nanoencapsulation technologies emerge as a promising solution to overcome these challenges. A systematic methodology involving keyword searches in databases was employed to gather relevant literature on LEO micro‐ and nanoencapsulation, providing an extensive overview of techniques, processes, encapsulating materials, and possible applications. Beyond established methods, emerging techniques were explored. This review highlights the critical role of encapsulation in enhancing the thermal and chemical stability, applicability, bioavailability, and controlled release of LEO.
