Oil Seed Protein Isolate and Process for Production

An oil seed protein isolate extraction process comprising, step-wise:

• a. separating hulls, if present, from desolvented, de-oiled oil seed flour,
• b. alkaline hydration of hull-free, desolvented, de-oiled oil seed flour with an aqueous solution:
• i) at a pH of 7-11,
• ii) at a temperature of 5-62° C.,
• iii) optionally including Na and/or Ca and/or Mg salt,
• c. separation of solids from the solution, producing a liquid fraction,
• d. precipitation and separation of protein from liquid fraction:
• i) at pH 3-7.5
• ii) at a temperature of 5-62° C.,
• e. dilution of the protein to produce a slurry,
• f. homogenization and sterilization of protein slurry, and
• g. drying protein slurry.
