Abstract
The potential applications of essential oils are limited by their natures as they are oxidized easily by light, heat, and other environmental factors. Essential oil impediments and their short shelf life promote the development and application of essential oil nanoencapsulation. Nanoencapsualtion techniques employed in formulation of essential oil nanocapsules are diverse. Therefore this paper present the review of nanoencapsulation technology applied on essential oil as well as the analysis of the bibliometric on term of essential oil nanoencapsulation technology. The review was conducted by investigate and study the literatures available on nanotechnology applied on essential oil. The bibliometric analysis was conducted by using Vos Viewer program in order to analyze the journals and articles published in scopus database. The search was performed on keywords of essential oil, nanoencapsulation, and nanoencapsulation specific techniques. Based on the direction of the size of the nanomaterial formulation, nanoencapsulation is classified into top down and bottom up technique. Nanoemulsion and liposomal entrapment are two top down methods that gain wide interest from researchers, while ionic gelation is the bottom up methods widely applied in essential oil nanoencapsulation. The bibiometric analysis of the publication on essential oil nanoencapsulation based on nanoemulsion and ionic gelation methods show that the trend of the essential oil nanoencapsulation performed via top down and bottom up techniques are mostly intended to investigate the pharmacological activities of the bioactive compounds of the essential oil as well as investigated for their application as drugs release system.
