Abstract: Protein concentrates and protein isolates, in addition to processes for the production of protein concentrates hydrolyzates thereof and protein isolates, are disclosed. In particular, the disclosure relates to a process for removing fiber from an oilseed meal, comprising: i) mixing an oilseed meal with a blending solvent, optionally water, saline solution, polysaccharide solution or protein containing solution, to form a mixture; ii) optionally adjusting the pH of the protein slurry to a pH of about 2 to about 10; iii) separating the mixture to form a protein slurry comprising soluble and insoluble proteins and an insoluble fiber fraction, and iv) hydrolyzing the insoluble proteins.

Abstract: Disclosed is an aqueous process for the preparation of a protein isolate and a hydrolyzed protein concentrate from an oilseed meal, comprising: 1) mixing an oilseed meal with an aqueous solvent to form a slurry; 1a) optionally treating the slurry with phytase; 2) separating the slurry with a solid/liquid separation to form a liquid phase comprising the aqueous solvent, soluble protein and oil; and a solid phase comprising insoluble protein; 3) separating the liquid phase to form an oil phase and an aqueous protein phase; 4) subjecting the aqueous protein phase to membrane filtration to obtain a protein solution and drying the protein solution to obtain the protein isolate, subjecting the insoluble protein to enzymatic hydrolysis, and 5) subjecting the hydrolyzed protein to membrane filtration to obtain an amino acid and peptide solution; and drying the amino acid and peptide solution to obtain the hydrolyzed protein concentrate.

Abstract: Protein concentrates and protein isolates, in addition to processes for the production of protein concentrates and protein isolates, are disclosed. In particular, the disclosure relates to the removal of fiber from an oilseed meal using low g-force centrifugation.
