Abstract:
A method for producing an oilseed protein product comprising:extracting oilseed material with an aqueous solution to form a suspension of particulate matter in an oilseed extract; passing the extract through a filtration system including a microporous membrane to produce a first permeate and a protein-enriched retentate, wherein the microporous membrane has an MWCO of at least 25,000 and a filtering surface with a contact angle of no more than 30 degrees; diafiltering the protein-enriched retentate through the filtration system to produce a diafiltration rententate and a diafiltration permeate, wherein the diafiltration retentate includes protein-enriched dissolved solids; combining the first permeate and the diafiltration permeate to form a combined permeate; and separating the combined permeate with a reverse osmosis membrane into an RO retentate and an RO permeate.
