摘要： The invention relates to a method of combined cell digestion and extraction of oil-containing seeds having an oil content of > 30% by mass, wherein production of a slurry from the oilseeds and ethanol is followed by a combination of cell digestion with a subsequent ethanolic extraction, wherein the smaller portion of the oil present in the seed cells of the oilseed and the alcohol-soluble constituents present therein are transferred to the ethanol in accordance with the dissolution capacity of the ethanol for the oil and the alcohol-soluble constituents, and another, greater portion of the oil is displaced from the seed cells of the oilseed by the ethanol, forming a free oil phase in the ethanol. The free oil phase is removed and, according to the invention, has semi-raffinate quality. The complexity of refining that has been reduced thereby is a result and an advantage of the method of the invention.
