Disclosed is a hydrolyzed oilseed protein concentrate having a protein content of about 65% to about 90% (w/w) and having a protein dispersibility index of at least 95.0% and wherein a 1.0% solution (w/w) of the hydrolyzed oilseed protein concentrate has a visible light transmittance of least 90.0%. Further disclosed is a process for the production of a hydrolyzed protein concentrate from an oilseed meal, comprising: i) mixing the oilseed meal with a blending solvent, optionally water, to form a first mixture； ii) optionally adjusting the pH of the first mixture to a pH of about 7.0 to about 10.0； iii) separating the first mixture to remove fiber from the first mixture and form a protein slurry and an insoluble fiber fraction, wherein the protein slurry comprises a soluble protein fraction and an insoluble protein fraction and the insoluble fiber fraction comprises insoluble fiber and a second insoluble protein fraction； iv) mixing the insoluble fiber fraction with a second blending solvent, optionally water, to form a washed insoluble fiber fraction and an extract； v) separating the washed insoluble fiber fraction from the extract； vi) mixing the washed insoluble fiber fraction with a third blending solvent, optionally water, to form a second mixture； vii) optionally adjusting the pH of the second mixture to a pH suitable for enzymatic activity； viii) mixing the second mixture with at least one protease to form a hydrolyzed protein extract； ix) separating the hydrolyzed protein extract from the second mixture to form the hydrolyzed protein concentrate and a second insoluble fiber fraction； and x) optionally drying the hydrolyzed protein concentrate.
