ABSTRACT
Because corn (maize, Zea mays) is the predominant feedstock for fuel ethanol in the United States and in many other countries, most of the chapters in this book focus on ethanol production and DDGS composition from corn. However, corn is not the only starch-rich crop that has been used as a feedstock for fuel ethanol. This chapter will describe eleven other starch-rich crops that have been used or have potentials to be used as feedstock for fuel ethanol. A useful website that includes information and references comparing various types of DDGS is hosted by the University of Minnesota (University of Minnesota, 2009). Another recent chapter described the commercial development of fuel ethanol plants using starch-rich and cellulosic feedstocks (Nghiem, 2008).
