The processing technology for extracting soybean oil is the 'physical pressing method'. The production process requires careful selection of raw materials. The oilseeds go through steps of impurity removal and stone removal before being crushed, steamed, and pressed to separate the oil from the oilseeds. This method retains the original flavor of the soybeans, resulting in a rich aroma, a long shelf life, and contains no additives, solvent residues, or soap content.
