This invention discloses a method for removing beany odor substances from soybean protein based on sonochemical effects and synergistic protease-targeted enzymatic hydrolysis, belonging to the field of food processing technology. The method first integrates ultrasonic treatment into an "alkali dissolution and acid precipitation" process to prepare a soybean protein solution, which undergoes targeted enzymatic hydrolysis and vacuum degassing, and finally freeze-drying to obtain low-beany-odor soybean protein. This invention utilizes green, low-energy ultrasonic treatment, which effectively promotes protein structure unfolding through short-duration high shear and cavitation effects, exposing enzyme cleavage sites and increasing the contact opportunity between the substrate and the enzyme. Furthermore, by adding a complex protease to specifically hydrolyze the key peptide bonds binding soybean protein to beany odor substances, the dissociation and release of beany odor substances are promoted, achieving effective removal of the beany odor from the soybean protein.
