Abstract

A method for preparing the high protein product from oilseed-based material is described. The high protein product provided by the process can be utilized in a wide variety of applications, including the preparation of food products for human consumption. The high protein product typically includes at least 85 wt. % protein (dry solids basis). The product is produced by a process which includes purifying an aqueous protein-containing extract through passage over a microporous membrane. The membrane generally has an MWCO of at least 25,000 and a filtering surface with a contact angle of no more than 30 degrees.
