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 parameters of cold press extraction process?

Cold press extraction process parameters were flow rate (c onstant) and rotational rate 40 rpm. Se eds moistu r e an d oil contents w er e determined. Also, to tal oil contents dete rmined by th e so lvent extraction m ethod. Obtained oils fatty acids analyzed w ith two commercial oils of Iran (COI) and Turkey (COT).

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 ).

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.
