Patent ID: 7989017

Claim:
A method of forming a food composition, which comprises: extracting a canola oil seed meal with an aqueous salt solution to form an aqueous protein solution, reducing the volume of the aqueous protein solution using ultrafiltration membranes to provide a concentrated protein solution having a protein content in excess of about 200 g/L, diluting the concentrated protein solution into chilled water having a temperature of below about 15° C. to form a cloud of protein micelles, allowing the protein micelles to settle to form a viscous, sticky mass and a supernatant, concentrating the supernatant, mixing the concentrated supernatant with the viscous, sticky mass, drying the resulting mixture to provide a substantially undenatured canola protein isolate having a protein content of at least about 90 wt %, and providing a food composition comprising a foodstuff and said substantially undenatured canola protein isolate as a component providing functionality in said food composition.
