摘要

Treatment of oleaginous and proteinic vegetable substances by adding a tannin-containing substance thereto, submitting the vegetable substance to mechanical pressure and friction forces in the presence of water at a temperature higher than normal ambient temperature while adjusting the amount of water such that it corresponds to a moisture content of about 10-15 percent of the vegetable substance, and separating the oily constituents from the proteinic constituents.
