The invention relates to a preparation method and application of a food antibacterial nanofiber membrane, and belongs to the technical field of food intelligent packaging membranes. The preparation method comprises the following steps: dissolving Arabic gum, polyvinyl alcohol and polyoxyethylene in deionized water to obtain a solution marked as a solution A; dissolving pullulan in deionized water to obtain a solution, and recording the solution as a solution B; inoculating a probiotic strain into the MRS bouillon culture medium, and culturing to obtain a probiotic solution; mixing the solution A, the solution B and the probiotic solution, and stirring to obtain a spinning solution; spinning by adopting an electrostatic spinning technology, injecting the spinning solution into an injector, setting corresponding parameters for spinning, taking tin foil paper as a receiving base material, and collecting through a rotary drum to finally obtain a nanofiber membrane, namely the edible antibacterial nanofiber membra
