The method comprises steps as follows: (1) raw material treatment: soybean is put into a drying oven to be dried, then crushed, dehulled, crushed again and screened with a standard sieve for standby use, and the water content rate of the soybean is determined; (2) conditioning: drinking water is added to the soybean raw material, so that the mass content of moisture is adjusted to be 12%-20%; (3) treatment and addition of enzymes: the enzymes are weighed in a certain mass proportion, water is added, the mixture is mixed uniformly and preheated in a water bath at the temperature of 42-45 DEG C, the soybean raw material obtained in the step (2) is added, and the mixture is stirred uniformly and left to stand for 4-8 h for standby use; (4) enzymic-method cold pressing: the soybean raw material is put into a cold-pressing expeller, the pressing temperature as well as the rotation speed and the pressure of a screw rod is set, pressing is repeated 2-3 times, pressed oil is collected, and a finished product, namely, soybean oil, is obtained after precipitation. The method has the advantages that the oil extraction rate is increased, the problem of solvent residues in traditional oil extraction is solved, and the safe and nutritional edible oil can be prepared.
