Abstract

A process for extracting oil and protein from vegetable oleaginous material comprises comminuting the material, grinding to a slurry in an aqueous alkaline solution of a pH such that substantially optimum solubility of protein is obtained, lowering the pH without precipitating the protein, heating to a temperature of from 25 to 80 DEG C., thereafter separating the material into concentrated oil emulsion, protein solution, and solids, treating the protein solution with acid to precipitate the protein, treating said concentrated oil emulsion to control the pH thereof according to the moisture content thereof so as to maintain the moisture-pH relationship within the region of emulsion breaking, and then mechanically breaking said oil emulsion to recover the oil. The oleaginous material may comprise (i) peanuts, the grinding being effected in an aqueous alkaline solution of pH 7,5 to 10 followed by adjustment to pH 7,5 to 7,75; (ii) tung nuts, the grinding being effected in an aqueous alkaline solution of pH 7,5 to 12 followed by adjustment to pH 10 to 12; (iii) cotton seed, the grinding being effected in an aqueous alkaline solution of pH 9 to 12 followed by adjustment to pH 9 to 11 ; (iv) soybeans.ALSO:A process for extracting oil from vegetable oleaginous material comprises comminuting the material, grinding to a slurry in an aqueous alkaline solution of pH such that substantially optimum solubility of protein is obtained, lowering the pH without precipitating the protein, heating to a temperature of from 25 to 80 DEG C., thereafter separating the material into concentrated oil emulsion, protein solution, and solids, treating said concentrated oil emulsion to control the pH thereof according to the moisture content thereof so as to maintain the moisture-pH relationship within the region of emulsion breaking, and then mechanically breaking said oil emulsion to recover the oil.
