  • 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.
  • Does cold pressed soybean oil scavenge radicals?
  • On the contrary, cold pressed soybean oil was characterized by remarkably lower 2,2-diphenyl-1-picrylhydrazyl (DPPH·) radical scavenging activity (17.4%) than cold pressed oils of hemp (76.2%), pumpkin seed (65.3%), rapeseed (51.2%), sunflower (23.8%), rice bran (23.7%), and flaxseed (19.3%) ( Siger et al., 2008 ).
  • Does cold pressed soybean oil contain trans fatty acids?
  • However, Brühl (1996) detected the presence of trans fatty acids (0.10%–0.15%) in cold pressed soybean oils. The author thus stated that trans fatty acids may occur due to high temperature drying of seeds before cold pressing and/or deodorization of cold pressed soybean oils or blending of cold pressed oils with refined ones.
  • 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.
  • 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 ).
  • How much phytosterol is in cold pressed soybean oil?
  • It is reported that the total phytosterol content of cold pressed soybean oil (3.2 mg/g) is close to that of cold pressed flaxseed (3.1 mg/g), and sunflower (3.2 mg/g) oils, and less than that of cold pressed corn (9.7 mg/g), and rapeseed (7.7 mg/g) oils ( Rudzińska et al., 2001 ).
