ABSTRACT
Distillers dried grains with solubles (DDGS) is a major type of distillers grains in the current market. By de„nition, distillers grains are cereal coproducts of the distillation process. There are two main sources of distillers grains. The traditional source is from brewers where beverage ethanol, such as beer or spirits, is produced, and a growing source is from fuel ethanol plants. Fuel ethanol can be produced from sugary, starchy, or cellulosic materials and has been highly concentrated to remove water and blended with other compounds to render the alcohol undrinkable. There are two major industrial methods for producing fuel ethanol from grains: wet milling and dry grind.
