Corn-based ethanol production is exponentially growing in the U.S. As the use of ethanol as a fuel source increases, so does the need to find valuable uses for coproducts of the production process, such as distillers dried grains with solubles (DDGS). DDGS is a good source of nutrients, energy, and protein. Currently DDGS is sold by ethanol processors as livestock feed, thereby increasing profit for the production plants. As the industry continues to grow, there will be a growing need to find additional uses for DDGS. Physical and chemical properties of coproduct streams are becoming increasingly investigated, as these characteristics …

One of the fastest growing industries in the United States is the fuel ethanol industry. Since 2000 there has been an increase of more than 300%. There was production of 4.9 billion gallons of ethanol in 2006. The major coproducts from this industry include Distillers Dried Grains with Solubles (DDGS) and carbon dioxide. DDGS is used as a livestock feed since it contains high quantities of protein, fiber, amino acids, and other nutrients. The goal of this study was to quantify various chemical and physical properties of DDGS, Distillers Wet Grains (DWG), and Distillers Dried Grain (DDG) from several plants …
