  • 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.
  • 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 ).
  • 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.
  • Can a press cake be used for soybean seeds?
  • Although it is not used for soybean, the mechanical press process is applied today for seeds with high oil content like sunflower, rapeseed etc., in general for pre-pressed purpose; the intermediate residual oil content in press cake is about 20%.
