Abstract
A method of treating ethanol production byproduct is provided by treating wet distillers grain or stillage with a solution containing at least one α-hydroxysulfonic acid to produce at least one fermentable sugar containing product. Fermentable sugar useful for the production of biofuels or ethanol can be produced from such methods. The α-hydroxysulfonic acid can be easily removed from the product and recycled.
