The invention discloses an extraction method of soybean proteins extracted from soybeans. The extraction method comprises the steps of soaking the soybeans in water and ethanol, then performing crushing and homogenizing, and then baking the homogenized soybeans to obtain soybean protein coarse powder; performing a mixing reaction on the soybean protein coarse powder, water, an alkaline solution and lipases, and performing ultrasonic centrifuging to obtain soybean protein fine powder; and finally performing sterilization so as to obtain the soybean proteins. Through a soybean protein extractiontechnology disclosed by the invention, the dissolution rate of the soybean proteins can be notably increased, so that the extraction rate of the soybean proteins can be increased; through treatment of ultrasonic waves on soybean powder mixed liquor, cavitation effects on soybean powder can be achieved, separation of the soybean proteins can be effectively promoted, and the purity of the soybean proteins can be further in
