摘要： The development of stable water-in-oil-in-water (W/O/W) emulsions for edible preservation coatings and films, utilizing their properties, deserves scientific attention. In this study, oregano essential oil and D-sodium erythorbate were simultaneously loaded into W/O/W emulsions, and the homogenization conditions of the W/ O/W emulsions were optimized. The structure and interactions of gum Arabic (GA) and whey protein isolate (WPI) as the outer phase were analyzed. Stable W1/O/W2 emulsions with excellent antimicrobial and antioxidant activities could be produced under the conditions of GA: WPI at 1:1 and W2: W1/O at 5:5. The diphenyl-1picrylhydrazyl radical (DPPH) and 2,2 '-azinobis-(3-ethylbenzenthiazoline-6-sulphonic acid) (ABTS) radical scavenging rates were 86.35 % and 89.35 %, and the inhibition zone diameters for S. aureus and E. coli were 14.03 +/- 0.42 mm and 14.17 +/- 0.70 mm, respectively. Finally, the W1/O/W2 emulsions were successfully applied to prepare chitosan-based films. This study has the potential to promote the application of W/O/W emulsions in food preservation, emphasizing the need for advancements for real-world adaptability.
