Abstract
The purpose of this study was to attempt the encapsulation of lemongrass (Cymbopogon citratus) essential oil utilizing spray drying technique. An array of process parameters including concentration of wall (15–30%), type of wall materials (maltodextrin, maltodextrin and gum Arabic mixture), and concentration of essential oil (0.5–2.0%) were thoroughly investigated. The results show that the use of sole maltodextrin as encapsulant gave microcapsules characteristics comparable to that of powder produced using maltodextrin and gum Arabic mixture. The encapsulation process that was performed with maltodextrin at the concentration of 30% as wall material and lemongrass essential oil at the concentration of 1.5% as core material showed highest drying yield (84.49%), microencapsulation yield (89.31%) and microencapsulation efficiency (84.75%). Encapsulated essential oils retained most of their major constituents in comparison with the bare essential oils without any significant compromise in product quality.

Summary
Due to their benefits, have been extensively utilized in various industries, including manufacture of antimicrobial agents, medicines and food additives, to meet the recently emerging demand for products of natural origin [1,2]. The lemongrass essential oil accounts for more than. Lemongrass essential oils have been reported to play an important role in the treatment of different diseases such as oily skin, scabies, acne, antibacterial, and antimicrobial [6]. Among the biological activities exhibited by lemongrass essential oil, antimicrobial activity figures prominently, possibly due to the presence of geraniol and citral isomers. The highly volatile nature and degradable properties of the oil are the main disadvantages limiting the use of lemongrass essential oil in the food and pharmaceutical sectors [1]
