  • Is cold pressed soybean oil linoleic?
  • One of these studies revealed that cold pressed soybean oil consists of linoleic (50.8%), oleic (24.6%), palmitic (10.2%), linolenic (7.6%), stearic (3.7%), and vaccenic (1.5%) acids, and trace amounts of myristic, palmitoleic, heptadecanoic, arachidic, eicosenoic, behenic, erucic, and lignoceric acids ( Tuberoso et al., 2007 ).
  • Does solvent extraction reduce -tocopherol in soybean oil?
  • Kania et al. (2004) reported that solvent extraction of soybean oil yielded higher total tocopherols content (1448 mg/kg) than cold pressing (1358 mg/kg), and the refining process led to the loss of ¦Á-tocopherol by 37%, ¦Â-tocopherol by 56%, ¦Ã-tocopherol by 17%, and ¦Ä-tocopherol by 34% in solvent-extracted soybean oil.
  • Are cold pressed soybean oils solvent-extracted?
  • Commercial soybean oils are commonly solvent-extracted and refined due to their high phosphatides contents. Hence, few studies exist on characterization of cold pressed soybean oils in the literature.
  • What are the problems of cold pressed soybean oil?
  • The fundamental problem of cold pressed soybean oils is the lack of deactivation step of lipoxygenase isoenzymes, which impair the stability and quality of the oil. Therefore, Engeseth, Klein, and Warner (1987) suggested to apply tempering procedure to soybeans before oil extraction.
