Method of removing pericarp from grain in recoverable form
First Claim
1. A method for debranning grain comprising treating the grain with hot water, followed by treating the grain with an aqueous solution of a strong base;
- and detaching pericarp from the grain to yield debranned grain.

Abstract
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.

32. The method of claim 32, in which potassium content of the grain is increased by no more than 0.15% by weight.

33. A method of debranning grain using aqueous base in which pH of un-neutralized endosperm is not appreciably increased.

34. A method of chemically or enzymatically modifying a grain, comprising treating the grain with water to create a permeability barrier in the endosperm of the grain between a portion of the grain outside the permeability barrier and a portion of the grain inside the permeability barrier;
- and chemically or enzymatically modifying the portion of the grain outside the permeability barrier, without modifying the portion of the grain inside the permeability barrier.
