Main Article Content
Most of volatile aroma compounds, which are characteristics of each plant essential oil, are not stable and can be volatilized during processing or long time storage. In addition, the essential oils show poor solubility property. Encapsulation techniques can enhance essential oil stability. Encapsulation of essential oils by cyclodextrins (CDs) can form inclusion complex, which helps increasing stability and solubility of essential oils. Preparation of inclusion complex depends on essential oil properties and CDs types. After inclusion complex between essential oils and CDs is formed, the thermal and irradiation stability can be improved as well as anti-oxidation property, antimicrobial property, and solubility. Moreover, the release of volatile aroma compounds in essential oils can be controlled by inclusion complex. With these unique properties of CDs inclusion complex, it can be applied into various food and medical industries.
