  • 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 -carotene?
  • Cold pressed soybean oil is characterized by lower β-carotene content (0.3–27.0 mg/kg) than cold pressed oils of linseed (150 mg/kg), pumpkin seed (5.5–150.0 mg/kg), rapeseed (1.7–80.0 mg/kg), corn (0.9–35.0 mg/kg), and flaxseed (0.7 mg/kg) ( Rafalowski et al., 2008; 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 α-tocopherol by 37%, β-tocopherol by 56%, γ-tocopherol by 17%, and δ-tocopherol by 34% in solvent-extracted soybean oil.
