The invention discloses a double Pickering emulsion and a preparation method thereof. Preparing a soybean water-insoluble aggregate into a peptide dispersion liquid by adopting ultrapure water, and performing ultrasonic treatment to obtain a soybean water-insoluble aggregate solution; preparing chitosan into a solution by adopting an acetic acid aqueous solution to obtain a chitosan solution; slowly dripping the chitosan solution into the soybean water-insoluble aggregate solution which is continuously stirred, and shearing and homogenizing to obtain a composite colloid system; and adjusting the pH value of the composite colloidal particle system to 3-5, mixing with grease, and shearing and emulsifying to obtain the product. The double emulsion has high stability, can be stored for more than four months without demulsification and oil leakage, has a double structure capable of keeping more than one month, has good rheological and digestive properties, and effectively improves the green sustainable application of soybean protein enzymolysis products. |
