Physical Properties Of Distillers Dried Grains With Solubles (Ddgs), Kurt A. Rosentrater
Physical Properties Of Distillers Dried Grains With Solubles (Ddgs), Kurt A. Rosentrater

The production of corn-based ethanol in the U.S. is dramatically increasing, and consequently so is the amount of coproduct materials generated from this processing sector. These streams are primarily utilized as livestock feed, which is a route that provides ethanol processors with a substantial revenue source and significantly increases the profitability of the production process. With the construction and operation of many new plants in recent years, these residuals do, however, have much potential for value-added processing and utilization in other sectors as well. Extensive research has been conducted into determining the nutritional properties of distillers dried grains with solubles …

The production of corn-based ethanol in the U.S. is dramatically increasing, and consequently so is the quantity of byproduct materials generated from this processing sector. These coproduct streams are currently solely utilized as livestock feed, which is a route that provides ethanol processors with a substantial revenue source and significantly increases the profitability of the production process. With the construction and operation of many new plants in recent years, these residuals do, however, have much potential for value-added processing and utilization in other sectors as well. This option holds the promise of economic benefit for corn processors, especially if the …

Corn, the most widely produced feed grain in the United States, accounts for more than 90% of the total value and production of feed grains. It is also used for food, industrial materials, and fuel ethanol production. Distillers grains, the major coproduct from ethanol manufacturing, are used as livestock feed. There are, however, other potential options, including value-added food, industrial, chemical, and energy applications. Fractionating distillers grains into concentrated streams of protein, fiber, and fat may be key to facilitating these types of utilization. Previous studies on other products have shown that fractionation is a promising mechanism for extracting valuable …
Methodology To Determine Soluble Content In Dry Grind Ethanol Coproduct Streams, Vykundeshwari Ganesan, Kurt A. Rosentrater, Kasiviswanathan Muthukumarappan
Methodology To Determine Soluble Content In Dry Grind Ethanol Coproduct Streams, Vykundeshwari Ganesan, Kurt A. Rosentrater, Kasiviswanathan Muthukumarappan

Distillers grains and syrup are coproducts from fuel ethanol dry grind processing. Ethanol manufacturing is dramatically increasing in the United States, primarily in Midwestern states, and thus the availability of these feed products is also growing. Confusion currently exists in industrial nomenclature regarding "solubles" in these streams because no standards are in place. In our study, dissolved materials were considered soluble matter. We developed a methodology to determine the dry basis soluble content in condensed distillers solubles (CDS) and distillers dried grains with solubles (DDGS). A mass balance analytical approach was initially used, but results were not in good agreement …

With the rapid growth in the fuel ethanol industry in recent years, considerable research is being devoted to determining distillers dried grains with solubles (DDGS) nutritional properties and to optimizing their inclusion in livestock diets; physical properties of these materials, however, have been largely ignored. Using standard laboratory methods, several physical properties for typical DDGS streams were determined, including moisture content, water activity, thermal properties (conductivity, resistivity, and diffusivity), bulk density, angle of repose, and color. The DDGS samples in this study were golden-brown in color and exhibited physical properties similar to other dry feed ingredients, such as hominy feed, …
