The invention relates to an enzyme method ultrasonic extraction method of walnut oil and walnut protein, which belongs to the food and the functional food field. Water is added into walnut kernel or walnut powder to be grinded into paste, protease or compound protease are added into to be performed hydrolization, and simultaneously ultrasonic processing is performed, then the walnut kernel or walnut powder is agitated to perform enzymatic extraction, and then centrifugal separation oil phase, protein peptide oil water phase and residual solid phase are performed; walnut oil is acquired by refining the obtained oil phase, which meets the requirements of green foods; the protein peptide aqueous solution can be directly used to produce degreased walnut protein nutrient milk, or to prepare walnut antioxidation peptide after performed nanofiltration, which is used in health products, food additives, cosmetics or daily chemical articles, or to produce nutrient condensed milk after being performed low temperature co
