Process for recovery of insoluble protein from steep water

摘要

An improved corn wet milling process is disclosed, in which gluten is recovered from steepwater by membrane filtration and is incorporated in a corn gluten meal product. The process can include the steps of steeping corn kernels in an aqueous solution, thereby producing steep water which contains gluten protein; membrane filtration of the steep water, thereby producing a retentate which has a higher concentration of the gluten protein than the original steep water; reducing the water content of the retentate; and incorporating the remaining retentate into a corn gluten meal product.
