Eucalyptus essential oil possesses significant antibacterial properties, but its fast evaporation and low stability hinder its practical applications. In this study, we developed a method to microencapsulate eucalyptus essential oil within a fish gelatin gel to improve its controlled release and antibacterial effects. The prepared microcapsules were characterized, and their antibacterial activities against selected bacteria were evaluated. Our findings indicate that fish gelatin gel can effectively encapsulate eucalyptus essential oil and enhance its controlled release properties. Moreover, the microencapsulated eucalyptus essential oil exhibited superior antibacterial effects compared to the non-encapsulated form. This research provides valuable insights into the potential use of fish gelatin gel as a carrier for essential oils, opening up new avenues for the development of natural antimicrobial agents. 1.
