Method for preparing high-stability Pickering emulsion based on cyclodextrin emulsifying property regulation and control

The invention belongs to the technical field of Pickering emulsion preparation, and particularly relates to a method for preparing a high-stability Pickering emulsion based on cyclodextrin emulsifying property regulation and control. The method comprises the following steps: firstly, dissolving cyclodextrin and modified molecules in a solvent, heating and stirring to obtain a solid stable particle solution; wherein the modified molecules are polysaccharide, protein macromolecular substances or amphiphilic micromolecules; then mixing the solid stable particle solution with vegetable oil, and carrying out homogenization treatment to obtain a Pickering emulsion; according to the present invention, the modified molecules are coated with the cyclodextrin or embedded into the cyclodextrin cavity, such that the property of the stable particles on the oil-water interface can be effectively adjusted so as to control the stability of the two-phase interface, such that the property of the Pickering emulsion can be adjus
