Interpretive Summary: In recent years, there has been a dramatic increase in grain-based fuel ethanol production in North America and around the world. Whether such production will result in a net energy gain or whether this is sustainable in the long term is under debate, but undoubtedly millions of tons of non-fermented residues are now produced annually for global trade in the form of distillers dried grains with solubles (DDGS). Consequently, in a short period of time a tremendous amount of research has been conducted to determine the suitability of ethanol co-products for various end uses. Distillers Grains: Production, Properties and Utilization (2011, by CRC Press, Baca Raton, FL) is the first book of its kind to provide in-depth and up-to-date coverage of 1) Historical and current status of the fuel ethanol industry in the U.S. Processing methods, scientific principles, and innovations for making fuel ethanol using grains as feedstock; 2) Physical and chemical properties of DDGS, assay methodologies for compositional analyses, and mycotoxin occurrence in DDGS; 3) Changes during processing (from grains to DDGS) and analysis of factors causing variations in compositional, nutritional, and physical values; and 4) Various traditional, new, and emerging uses for DDGS (including feed for cattle, swine, poultry, fish, and other animals, feedstocks for cellulosic ethanol, biodiesel, and other bio-energy production, and substrates for food and industrial uses. Appealing to all who have an interest in fuel ethanol production, distillers grains, and their uses, this comprehensive reference sharpens the readers’ understanding of distillers grains and will promote better utilization of ethanol co-products. Animal and food scientists, feed and food technologists, ethanol plant managers and technicians, nutritionists, academic and governmental professionals, and college students will find the book most useful.

Technical Abstract: The book, Distillers Grains: Production, Properties and Utilization, brings together cutting edge information on many aspects of DDGS. It consists of six major sections, having 26 chapters in total. Section 1 has six chapters and covers introduction, perspectives, history, structure and composition of raw grains, and manufacturing processes from corn as well as other grains. Section 2 deals with physical characteristics, chemical composition, and methodologies for analysis of DDGS; additionally, two chapters provide in depth discussions of DDGS lipids and mycotoxin occurrence. Section 3 consists of four chapters, and covers traditional use of DDGS as livestock feed (beef cattle, dairy cattle, swine, and poultry). Section 4 has three chapters and discusses further uses of DDGS, including feed for fish, feed for other animals, as well as food ingredients for human consumption. Some emerging opportunities are covered in Section 5, including use of DDGS in bioplastics and as feedstocks for bioenergy (thermochemical conversion, anaerobic digestion, pretreatment for cellulosic ethanol production, and extraction and use of DDGS lipids for biodiesel production). The last section covers process improvements, including new and improved enzymes for fuel ethanol production, and fractionation of DDGS. It ends with a chapter of concluding thoughts. The 26 chapters were authored and co-authored by over 34 scientists with specific expertise in their respective fields. To ensure high quality, each chapter was peer reviewed by at least two external professionals who are experts in their fields. Furthermore, extensive lists of references in each chapter should be helpful to readers who wish additional information for a specific topic. Therefore, the book is a comprehensive compilation and discussion of distillers grains for both the scientific and technical communities, including the feed and ethanol industries brings together cutting edge information on many aspects of DDGS.
