solvent extraction of oil from soybeans in ethiopias
FACT SHEET
In the 1930s, soybeans were mechanically processed using hydraulic or screw presses (often known in the industry as expellers), which squeezed out the oil of the heated or cooked soybeans. In the late 1940s and early 1950s, most of the industry converted to the solvent-extraction process, which removes more oil from the soybean.
