Abstract

Essential oils (EOs) are volatile aromatic compounds derived from spice plants and fragrant animals. Its insecticidal, antioxidant, and antibacterial properties, among others, have a significant research value. However, the unstable components severely restrict the applications of essential oils. Therefore, selecting the appropriate encapsulating material and the controlled-release mechanism is crucial to provide the best bioavailability and stability of essential oils. At present, it has been reported that several encapsulating materials are being employed to release essential oils to alleviate the issue of instability and volatility. This study will summarize the frequently utilized encapsulating materials and controlled-release methods for essential oils in recent years and give insight into the further design of encapsulating systems, development of bioactivity, and expansion of essential oil application sectors.

Novelty impact statement

  1. Mesoporous silica and zeolites are being studied for use as encapsulating materials for essential oils.
  2. Natural encapsulating materials have applicability in the food industry.
  3. Light and temperature-stimulating responses are suitable for sustained controlled-release for essential oils.
