The invention discloses a
soybean oil production method. The method comprises the following steps that 1, soybeans are cleaned, and water is added for stirring and
fermentation; 2, the fermented soybeans are broken and peeled through a breaker, the broken soybeans are pressed into blanks,
ultraviolet light sterilization is conducted, and secondary
fermentation is conducted after sterilization is conducted; 3, high temperature
steaming is conducted after second
fermentation of the soybeans is completed till the soybeans are completely well-cooked, and the well-cooked soybeans are pressed into a cake to be put into a hydraulic
machine, squeezing is conducted, and the oil is obtained; 4,
filtration is conducted on squeezed thick oil, hydration and deodorization are conducted, vacuum
filtration is conducted, and product oil is obtained. The
soybean oil production method has the advantages that high-quality soybeans are adopted, pure physical squeezing is conducted,
preservative and additives are not contained, other blend oil materials do not exist,
solvent residues and alkaline substance residues do not exist, original
flavor of the soybeans is kept, the nutritional components of the soybeans are not destroyed, the technology is reasonable, the steps are simple,
energy consumption is low, the produced product oil is green, pure natural and healthy, and the requirements of people are met.
