The invention discloses a method for carrying out enzymatic hydrolysis. The method comprises the following steps: adding water into protein, evenly stirring, transferring the mixture to an electrophoresis tank, carrying out electrophoresis under a voltage of 80 to 120 V, collecting the protein solution after electrophoresis, dissolving the protein by an enzymatic hydrolysis buffer solution containing trifluoroethanol, subjecting the protein to reduction and alkylation treatments, adjusting the pH value of processed protein to 7.5-8.5, then adding trypsase accounting for 90 to 98% of the protein solution, and carrying out enzymatic hydrolysis to obtain polypeptide; wherein the work electrode in the electrophoresis tank is modified by oxidation-reduction enzyme and Zn-Al layered double hydroxides. The provided method can obtain peptides suitable for liquid chromatogram-mass spectrum (LS-MS) analysis, and provides stable and reliable samples for proteomics analysis.
