Claim:
1. A process for separating components of a source stream containing fibers, water, protein and oil, said process comprising: (a) passing a source stream comprising water, oil, protein and fibers through a plate separator producing a fiber slurry comprising predominantly fibers and a first liquid fraction comprising predominantly a mixture of water, oil, and protein; (b) separating the fiber slurry into a fiber stream and a second liquid fraction containing predominantly a mixture of water, oil and protein by pressing the fiber slurry with a first press; (c) separating the first liquid fraction into (i) an oil stream containing predominantly oil, (ii) a protein stream comprising predominantly protein, and (iii) an aqueous stream containing predominantly water, said separating the first liquid fraction comprises treating the first liquid fraction with a demulsifying composition to cause the protein to solidify, said demulsifying composition being added to the first liquid fraction at a level of about at least about 5 ppm on a dry weight basis.
