Abstract： In this paper， Pickering emulsion was prepared by coating cinnamon essential oil with soy protein isolate/gum arabic as wallmaterial，andadded to chitosan/guar gum film to make the film have sustained release antibacterial properties.It was determined by particle size and polydispersity index that the emulsionsystem was the most stable when the mass ratio of soy protein isolate/gum arabic was 1：1 .When the amount of emulsion added is 8% ，the barrier properties and optical properties of the film are the best.The pork preservation experiment shows that the composite film containing Pickering emulsion can extend the preservation time by at least 4 d.
