The invention discloses a novel preparation method of crosslinking modified starch microspheres. The novel preparation method of the crosslinking modified starch microspheres comprises the following steps: firstly, using modified starch as a raw material, and preparing a modified starch solution with the concentration of 5 to 30 percent g/ml; secondly, adding a certain amount of polyvinyl alcohol solution as a modifier, adding the prepared modified starch solution into an oil phase containing an emulsifier; thirdly, carrying out high speed emulsification by a shearing machine, wherein the emulsifying speed is 500 to 2000rpm and the time is 10 to 20 minutes, and the like. According to the novel preparation method disclosed by the invention, a unique cross-linking agent which is divinyl sulfone (DVS) or sodium tetraborate decahydrate is adopted and the existing cross-linking problems are greatly improved, thereby obtaining a more stable and rapid crosslinking reaction and better product performance.
