In contrast, some advanced technologies such as enzyme-assisted, supercritical fluids, deep eutectic solvent, and ionic liquids seem less efficient than ordinary processes using hexane for soybean oil extraction. The best alternatives for replacing hexane seem to be ethanol, ethyl acetate, the terpenes, 2-MeTHF, and CPME.
How does hexane extraction work?
As the solvent (usually hexane) passes down through the bed of oil-bearing material, the oil is dissolved in the solvent and carried away. When properly carried out with stages of extraction (as will be described), the extraction process results in a very good separation of the edible oil from the solids or nutritious meal fraction.
What solvent is used in soybean extraction?
In solvent extraction, flaked soybeans are washed with hot solvent, typically hexane, to separate the solids from the fats. Multiple washes dissolve the oil and carry it away. This oil solvent combination is also known as the miscella. The remaining material is the wet meal and solvent, also known as the marc.
How is soybean oil extracted?
Yet, some operators overlook a critical step in their soybean oil extraction process to save significant time and energy. In solvent extraction, flaked soybeans are washed with hot solvent, typically hexane, to separate the solids from the fats. Multiple washes dissolve the oil and carry it away.
