Storage of Cereal Grains and Their Products

Dr. Kurt Rosentrater is an Associate Professor in the Departments of Agricultural and Biosystems Engineering as well as Food Science and Human Nutrition at Iowa State University. He also serves as Executive Director of the Distillers Grains Technology Council, which is an organization focused on education and outreach to improve the use of beverage and fuel alcohol coproducts in animal feeds. He is actively pursuing a research program to improve the sustainability of the grain-based alcohol industry. His research is focused on developing processes to add value to, and more effectively utilize cereal-based fermentation coproducts. He is developing sustainable, economical materials and products from distillers grains, such as enhanced feeds, foods, bioplastics, biocomposites, industrial intermediates, additional biofuels, and bioenergy. Over the last several years, his work has helped advance the capabilities of ethanol plants to produce, transport, store, and utilize coproducts, which has led to improved utility for livestock producers and increased economic values for ethanol manufacturers. His expertise is in value-added coproduct development, alternative recycling and reprocessing strategies for biofuel coproduct streams, improvements in processing efficiencies, life cycle assessment, techno-economic analysis, modeling and simulation of processing systems, plant layout, and process design. He attended Iowa State University where he received his BS, MS, and PhD in Agricultural and Biosystems Engineering. He is a member of the American Society of Agricultural and Biological Engineers, the American Association of Cereal Chemists, the Institute of Food Technologists, the American Society for Engineering Education, the American Physical Society, and Sigma Xi Honorary Research Society.
