The invention discloses a preparation method of an antibacterial Pickering emulsion and an application of the antibacterial Pickering emulsion. According to the preparation method disclosed by the invention, firstly, thymol-loaded zein-pectin composite nanoparticles are prepared by utilizing an anti-solvent anti-precipitation method, and the nanoparticles are uniform in form and size and have a certain antibacterial effect. Secondly, in order to improve the antibacterial effect, thymol and star anise essential oil are combined, the star anise essential oil is stabilized by using the zein-pectin composite nanoparticles loaded with thymol, and the oil-in-water type Pickering emulsion is prepared. According to the preparation method, the preparation process is optimized, the optimal parameters are obtained, and the prepared Pickering emulsion is small in droplet particle size, uniform in distribution and long-term in stability. Finally, the prepared Pickering emulsion is applied to the snakehead fish fillets, an
