A process of producing a peanut oil, comprising a first stage of immersing peanut seeds cleared of the skins in hot water for a predetermined period of time, cooking the resultant peanut seeds in an equal volume of hot water at a predetermined temperature under a predetermined pressure for a predetermined period of time, grinding the cooked peanut seeds into the form of slurry, diluting the slurry with an equal volume of hot water, and mechanically fractionating the diluted slurry into a liquid fraction and a solid fraction; a second stage of mechanically fractionating the liquid fraction into a water fraction, an oil fraction and a residual solid fraction; and a third stage of adding an aqueous solution of salt to the liquid fraction obtained in the second stage for forming a layer of peanut oil over a layer of solid constituents, and separating the layer of the peanut oil from the layer of the solid constituents. |
