Disclosed is a processing method of a self-reinforced starch-based multifunctional material, and belongs to the technical field of starch deep processing. The processing method takes bulk starch as a base material, including the following steps: firstly reacting starch nanoparticles with an organic acid anhydride reagent and adding a bacteriostatic agent to prepare composite nanoparticles, then mixing the composite nanoparticles with the bulk starch, an etherifying agent, a crosslinking agent, a plasticizer and the like, and finally preparing a starch-based multifunctional material by dry extrusion modification combined with a starch-based nanoparticle assembly and reinforcement technology. The method of the disclosure is simple and convenient in step, mild and controllable in reaction, and continuous and green in production. The obtained product has good mechanical properties, high barrier properties and high antibacterial properties, can be applied to many fields such as food, textiles, daily chemicals and medicine, and has a broad market prospect.
