  • 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 ).
  • 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 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.
