“…The optimal solution to this problem is the simultaneous preparation of soy protein and oil using an enzyme-assisted aqueous extraction method, and there have been numerous studies ( 19 , 20 ). Moreover, the proteins prepared using this method have significant physiological functionality ( 21 ). The failure of the enzyme-assisted aqueous extraction method to replace the traditional process for the preparation of soybean oil is mainly attributed to the high cost of the enzymes used and the instability of the conditions after scale-up production.…”
