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.
Claims22
An oilseed protein hydrolyzate having a protein content of about 65% to about 90% and having a protein dispersibility index of at least 95.0% and wherein a 1.0% solution (w/w) of the protein hydrolyzate has a visible light transmittance of least 90.0%.
A process for the production of a hydrolyzed protein concentrate from seed meals selected from the group consisting of canola seed meal and rapeseed meal, said seed meals comprising fiber, soluble protein and insoluble protein, comprising the steps of:
- i) mixing the seed meal with a blending solvent, optionally water, to form a first mixture;
- ii) adjusting the pH of the first mixture to about 7.0 to about 10.0;
- iii) separating a protein slurry from the first mixture to form an insoluble fiber fraction, wherein the protein slurry comprises:
- a) a soluble protein fraction;
- and
- b) an insoluble protein fraction;
- and wherein the insoluble fiber fraction comprises:
- a) insoluble fiber, and
- b) a second insoluble protein fraction;
- wherein the protein is substantially in the protein slurry and the fiber is substantially in the fiber fraction;
- iv) optionally mixing the predominantly 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.
