The present disclosure provides systems and methods for the recovery of protein species from wet mill grain process streams. Systems and methods of the present disclosure may be integrated with a wet mill grain process to separate out protein species that may limit efficiency of the grain process and produce one or more product streams comprising these separated protein species. A feed stream may be fractionated by at least two membranes into retentate and permeate streams. Removing larger proteins through the membrane fractionation may allow previously soluble prolamin products in the permeate stream(s) to precipitate. The recovered protein species may include prolamin, such as zein from a corn grain feed.
