Abstract

Essential oil is a volatile solution with a specific odor, it usually is lighter than water and is not soluble in polar solutions [6]. All essential oils are labile and volatile compounds evaporate in the environment so they lose their biological effect [7]. A few methods are used to protect essential oil, for example, microencapsulation. Microencapsulation is usually a simple physical method and many excipients’ variations could be used [1,4,5]. The shell of microcapsules protects volatile compounds from oxidation, temperature, and moisture influence [2]. In this study, nutmeg essential oil was used and microcapsules with sodium alginate were prepared.
