“…During the homogenisation process, the stirring speed was 500 rpm, referring to the research of Pujiastuti and the authors in 2017, which explained that the stirring speed affects the particles' size. The greater the speed, the smaller the resulting particle size will be (Pujiastuti et al, 2017). However, Sirojuddin and the authors in 2015 argued that increasing the stirring speed increases the strength and frequency of collisions between particles, causing the breakdown of the coating material and the release of the core substance into the solvent (Sirojuddin et al, 2015).…”

Background: The way to improve the stability of jeringau rhizome essential oils is microencapsulation using β-cyclodextrin. Objective: To determine the efficiency of coating the jeringau rhizome essential oil with β-cyclodextrin and examine its thermostability. Method: The microencapsulation method used was freeze-drying with a ratio of 1:20 and 1:30. Results: The microcapsule efficiency at the ratio of 1:20 and 1:30 was 81.67% and 60.70%, respectively. The thermostability test results showed that the degradation constant of 1:20 microcapsule at 50oC and ambient temperature was 0.0054 and 0.0029, respectively, with a half-life of 128.33 hours and 238.97 hours. Meanwhile, the degradation constant of 1:30 microcapsule was 0.0182 and 0.0080, with a half-life of 38.07 hours and 86.63 hours. Conclusion: The highest efficiency is in the ratio of 1:20 with a percentage of 81.67%. In the thermostability test, the 1:20 microcapsule was better protected and had a longer half-life than the 1:30 microcapsule.

“…When an inclusion complex is formed with highly volatile compounds as 'guest' molecules, it enables the slow and gradual release of the volatile compounds, due to which BCD has been used in a variety of applications such as in the formation of inclusion complexes of BCD and citronella oil that perform successful repellent activity against A. aegypti, and the inclusion of permethrin in BCD molecules that are grafted in cotton fabric, to obtain effective residual insect repellent activity against A. aegypti and Anopheles stephensi (Songkro et al, 2012). Pujiastuti et al (2017) have encapsulated citronellal, which is an active repellent compound, in BCD using the emulsion-based method followed by freeze drying of the complex. The best controlled release properties were exhibited by the complex consisting of 1:1 weight-based ratio of the active _________________________________________________ *Correspondence: sdmchin@sjp.ac.lk © University of Sri Jayewardenepura compound and BCD (Pujiastuti et al, 2017).…”

The necessity of developing insect repellents with highly effective sustained release properties has attracted more attention due to the vast spread of arthropod-borne diseases such as dengue and malaria, which must be controlled with proper measures, and also due to the devastating damage caused by severe infestation of insect pests on crops and stored food. Natural and synthetic insect repellents are used against insect vectors and insect pests. Topical insect repellent formulations should be less toxic, less irritant, and less skin permeable. Irrespective of the type and form of the repellent, the mechanism of action depends on the formation of a vapour barrier/ odour barrier, that would deviate the insect from reaching the host. Synthetic insect repellents are highly efficient but due to their high toxicity, degradation resistance, and bio accumulation, they raise environmental and ecological issues. Due to the adverse effects caused by synthetic insect repellents, more attention is given to insect repellents consisting of natural products.Essential oils are among the widely used natural insect repellents available due to their biocompatibility and non-toxicity. High volatility of essential oils is the major problem that hampers the application of essential oils as insect repellent agents. The high volatility that reduces the length of application, and its activity can be successfully addressed by the formulation of slow-release insect repellent composites by incorporating essential oils into adsorbing or encapsulating matrices. Zeolites, montmorillonite, β-cyclodextrin, polymeric materials, and electrospun nanomaterials are commonly used to develop slow-release formulations with essential oils. Among these, polymeric microcapsules are the most extensively studied and developed slow-release insect repellent systems that are based on natural and synthetic active compounds.

Essential oils (EOs) are known as any aromatic oily organic substances which are naturally synthesized in plants. Exhibiting a broad range of biological activities, EOs have played a key role in numerous industries for ages, including pharmaceutical, textile, and food. However, the volatility and high sensitivity to environmental influences pose challenges to the application of EOs on industrial scale. Microencapsulation via the spray-drying method is one of the promising techniques to overcome these challenges, thanks to the presence of wall materials that properly protect the core EOs from oxidation and evaporation. By optimization of key factors related to the infeed emulsion properties and spray-drying process, the encapsulation efficiency and retention of encapsulated EOs could be significantly improved, thus allowing a wide range of EO applications. This review attempts to discuss on different determining factors of the spray-drying process to develop an effective encapsulation formula for EOs. Furthermore, recent applications of encapsulated EOs in the fields of foods, pharmaceuticals, and textile industries are also thoroughly addressed.
