| abstract |
The protein/starch bond is broken mechanically by wet attrition milling rather than by cooking or with chemicals alone. The grain particles are milled to a particle size sufficiently small to break the bond between starch and protein and sufficiently large to retain substantially all of the starch granules intact. The protein is then extracted with ethanol and alkali solvents, separated and dried to form protein and/or protein isolate. The intact starch granules are cleaned and dried. |
