Hemp seed protein pickering particles and a method for preparing hemp seed pickering emulsion

A method for preparing hemp seed protein-containing Pickering emulsion, comprising:

• (1) crushing hemp seeds, removing oil from the hemp seeds by n-hexane solvent extraction and collecting a remaining solid part, and then performing alkali-soluble acid precipitation treatment on the remaining solid part to obtain a hemp seed protein powder;
• (2) dissolving the hemp seed protein powder in a formic acid solution to prepare a hemp seed protein stock solution, and then adding the hemp seed protein stock solution dropwise into deionized water under stirring conditions to form a suspension;
• (3) centrifuging the suspension, removing a bottom precipitate and then adjusting pH value, precipitating hemp seed protein nanoparticles, and then carrying out suction filtration to obtain a protein particle precipitate;
• and freeze-drying the protein particle precipitate to obtain dried hemp seed protein Pickering particles;
• and
• (4) adding the hemp seed protein Pickering particles, maltodextrin, and corn syrup solids into water for fully dissolving to form a homogeneous suspension, adding vegetable oil into the suspension prepared, and then mixing well to obtain Pickering emulsion;
• wherein the n-hexane has a ratio to the hemp seeds crushed of (5:1)-(10:1) (w/w).
