Potential Bleaching Techniques For Corn Distillers Grains, Jessica A. Saunders, Kurt A. Rosentrater, P. G. Krishnan Jan 2008

Potential Bleaching Techniques For Corn Distillers Grains, Jessica A. Saunders, Kurt A. Rosentrater, P. G. Krishnan

The ethanol industry is booming and extensive research is now being pursued to develop alternative uses for Distillers Dried Grains (DDG) and Distillers Dried Grains with Solubles (DDGS), coproducts of the ethanol production process. Currently, DDG and DDGS are used exclusively as livestock feed. The low starch, high protein and high fiber coproducts appear to be ideally suited for diets treating medical conditions such as diabetes and Celiac’s disease by virtue of their chemical composition. Processing methods need to be investigated to create flours that can be used effectively. Modifying aspects such as color, odor and baking functionality may eventually …

Distillers Dried Grains with Solubles (DDGS) is widely recognized as a highly nutritious animal feed ingredient. With the exponential growth of the fuel ethanol industry in the past several years, significant quantities of distillers grains are now being produced. To effectively utilize these feeds in the domestic market, these coproduct streams have to be transported greater distances, and must be stored in various structures until final use. Unfortunately, DDGS flow is often problematic, as it frequently becomes restricted by caking and bridging during storage and transport. This issue may arise from a number of factors, including storage moisture, temperature, relative …

A field study was conducted to examine the fate of E. coli and enterococci transport from three bare soil types receiving cowpat treatments and develop relationships between bacterial partitioning and phosphorous and carbon transport. Particles sizes to which cells preferentially associated were also identified.
