An aqueous soya suspension is prepared by grinding soya beans in the presence of water at a temperature of from 90.degree. to 100.degree. C. to form a dispersion of particles of which the majority have dimensions of the order of 100 to 500.mu.; heating the dispersion by the injection of steam to a temperature of from 120.degree. to 160.degree. C. thereby destroying the antitrypsin factor; and grinding the dispersion to form a suspension containing corpuscules of protein and fat with dimensions of the order of 2 to 10.mu. and cell wall debris of which the largest dimension does not exceed substantially 40 to 300.mu.. The soya suspension may be consumed as such or used as a starting material for the production of foods such as cheese or used as a base for the production of beverages such as a cows' milk substitute.

Method of producing an aqueous soya suspension

A process for isolating a protein fraction from an aqueous solution or suspension containing the said fraction in admixture with other substances, which comprises subjecting the aqueous solution or suspension to ultrafiltration to obtain a retentate, diluting the retentate, subjecting the diluted retentate to at least one further ultrafiltration treatment and recovering a retentate containing the protein fraction.
