A method for debranning grain, such as corn, involves treating the grain with hot water, followed by (1) treating the grain with an aqueous solution of a strong base and (2) detaching pericarp from the grain. Ethanol may be produced by hydrolyzing debranned grain produced by this method to sugars, and fermenting the sugars to ethanol. Alternatively, chemically or enzymatically modifying grain involves treating the grain with water to create a permeability barrier in the endosperm of the grain, and chemically or enzymatically modifying the portion of the grain outside the permeability barrier.
