The invention belongs to the field of food component separation and preparation, and particularly relates to a method for synchronously separating olive kernel oil and preparing antioxidant peptide. The method is characterized in that neutral protease is used, the dosage of the protease is 0.5-1.0%, and when the reaction temperature is 30-40 DEG C, the enzymolysis reaction time is 30-60 min, the centrifugal rotating speed is 10000 rpm, the centrifugal time is 10-15 min, the olive oil separation rate can reach 90%, the protein hydrolysis degree can reach 80%, and the hydroxyl radical inhibitionrate can reach 70%. According to the method, olive kernels are comprehensively developed and utilized, the quality of the obtained olive kernel oil is good, the oxidation resistance of polypeptide liquid is good, and the additional value of agricultural products is increased.
