  • Hemp seed protein pickering particles and a method for preparing hemp seed pickering emulsion
    Patent number: 12679862
    Abstract: Disclosed are hemp seed protein Pickering particles as well as a preparation method and application thereof, belonging to the field of multi-component restructured foods. The preparation of Pickering emulsion based on hemp seed protein Pickering nanoparticles includes: preparing hemp seed protein Pickering particles by using an anti-solvent precipitation method under the condition of taking hemp seed protein as a raw material, formic acid and water as solvents; then, adding the prepared hemp seed protein Pickering particles into water together with maltodextrin and corn syrup solids for fully dissolving to form a homogeneous suspension; and adding vegetable oil into the suspension and mixing well to obtain the Pickering emulsion. The Pickering emulsion is high in stability, and powdered oil constructed by using same has the advantages of being environmentally-friendly, cost-saving, and easy to achieve high stability and high unsaturation, thus having wide application value in food and medicine fields.
