ABSTRACT:
A process for the extraction of oilseeds which comprises steps for extracting oil from oilseeds by contacting the seeds in a presoaking zone with an isopropanol-based presoak solvent to obtain presoaked seeds, extracting the presoaked seeds by contact with an isopropanol-based extraction solvent in a multi-stage countercurrent extraction zone to obtain an extraction miscella and an extracted seed meal, and recovering oil from the extraction miscella. Processing efficiency is enhanced by the presoaking contact step when the relative water content of the presoak solvent is less than that of the extraction miscella.
