ABSTRACT
Clove essential oil (CEO) exhibited potent antibacterial efficacy and are obtained from Eugenia caryophyllata tree flower buds. Herein, CEO nanoemulsions were prepared using various concentrations of casein protein treated with ultrasound for different time interval. The study demonstrated that CEO nanoemulsions with 5% casein protein subjected to ultrasound for 10 min displayed the most minimal particle size. The pullulansodium alginate film incorporated with nanoemulsions treated with ultrasound exhibited enhanced physico-mechanical characteristics. Based on the structural analysis, the application of ultrasonic treatment improved intermolecular compatibility and organized molecular structure by strengthening hydrogen bonds. Furthermore, the composite film displayed remarkable efficacy against E. coli and S. aureus as well as longer retention of essential oils. The use of the developed films to protect cherry fruits and mushrooms produced promising results, emphasizing their potential in food packaging applications.
