Rosentrater Co-editor of Distillers Grains Book

Kurt Rosentrater, assistant professor in agricultural and biosystems engineering and Center for Crops Utilization Research affiliate, co-edited Distillers Grains: Production, Properties and Utilization, which was published last summer. The book is a comprehensive collection of information on distillers grains and serves as a resource for anyone connected with the ethanol and distillers grains industry. Along with Rosentrater, the book was co-edited by KeShun Liu, a research chemist with the USDA Agricultural Research Service.

The idea for the book came from discussions between Rosentrater and Liu revolving around the fact that the industry lacked a solid resource on distillers grains. In recent years there has been a dramatic increase in grain-based fuel ethanol production in North America and elsewhere. Millions of tons of non-fermented residues are 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 DDGS for various end uses, especially livestock feeds. More than 35 experts contributed to the book in order to have as many people involved in the industry from every facet, beginning with the corn kernel, to new production processes and products.

The book includes research summaries on the use of DDGS in beef, dairy, swine, and poultry, as well as uses in pet foods and other types of livestock feeding, including aquaculture. The book also provides information on the physical and chemical properties of DDGS, methodologies for composition analyses, chemical changes during ethanol processing, and factors causing variations in the compositional, nutritional, and physical values of DDGS.

The book highlights several new and emerging uses, such as feedstocks for cellulosic ethanol and biodiesel production, and substrates for food and other industrial uses. The book also includes information on new enzymes used in ethanol production, and the impact of fractionation, as well as extraction of DDGS lipids.
