Abstract:
1. A process of preparing a canola protein isolate from canola oil seed meal, which comprises: (a) extracting the canola oil seed meal to cause solubilization of the protein in the canola oil seed meal to form an aqueous protein solution having a pH about 5 to about 6.8, (b) separating the aqueous protein solution from residual oil seed meal, (c) increasing the protein concentration of said aqueous protein solution while maintaining the ionic strength substantially constant by effecting ultrafiltration of the aqueous protein solution to provide a concentrated protein solution, (d) subjecting the concentrated protein solution to diafiltration, (e) diluting the diafiltered protein solution into chilled water having a temperature below 15° C. to cause the formation of discrete protein micelles in the aqueous phase, (f) settling the protein micelles to form an amorphous, sticky, gelatinous, gluten-like protein micellar mass, and (g) recovering the protein micellar mass from supernatant as said canola protein isolate, the protein micellar mass having a protein content of at least 90 wt % (N×6.25) on a dry weight basis.
