Quantifying Total And Sustainable Agricultural Biomass Resources In South Dakota—A Preliminary Assessment, Kurt A. Rosentrater, Dennis Todey, Russell Persyn

Conversion of biomass is considered the next major advance in biorenewable fuels, energy, and products. Wholesale conversion to biomass utilization could result in removal of current crop residues from agricultural fields (on prime agricultural lands) or even implementation of different crops and cropping strategies (i.e., switchgrass on marginal lands). To date, the driver for biomass processing has been economics and limitations on the conversion of the lignocellulose. Over the last forty years significant investments and resultant changes in management practices in the agricultural sector have focused on soil and water conservation. One of the major efforts has focused on conservation-till …

The production of corn-based ethanol in the United States is dramatically increasing, and consequently, so is the quantity of generated coproducts, all of which are currently fed to livestock. Distillers Wet Grain (DWG) is one of these coproduct feeds. Many studies have investigated the nutritional properties of DWG and the response of livestock (primarily beef and dairy) to inclusion of these ingredients in their diets. To date, physical properties have been largely ignored, but they are needed for the design of storage facilities and equipment. The objective of this research was to quantify physical and chemical property values for typical …

The ethanol industry is booming. And extensive research is currently 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. previous research has shown promising avenues for the use of DDG and DDGS in human foods. The low starch, high protein and high fiber grains seem ideally suited for medical conditions such as diabetes and Celiac's disease. Processing methods need to be investigated to create functional flours that can be used effectively. Refining aspects such as …

Corn-based ethanol production is exponentially growing in the U.S. As the use of ethanol as a fuel source increases, so does the need to find valuable uses for coproducts of the production process, such as distillers dried grains with solubles (DDGS). DDGS is a good source of nutrients, energy, and protein. Currently DDGS is sold by ethanol processors as livestock feed, thereby increasing profit for the production plants. As the industry continues to grow, there will be a growing need to find additional uses for DDGS. Physical and chemical properties of coproduct streams are becoming increasingly investigated, as these characteristics …

One of the fastest growing industries in the United States is the fuel ethanol industry. Since 2000 there has been an increase of more than 300%. There was production of 4.9 billion gallons of ethanol in 2006. The major coproducts from this industry include Distillers Dried Grains with Solubles (DDGS) and carbon dioxide. DDGS is used as a livestock feed since it contains high quantities of protein, fiber, amino acids, and other nutrients. The goal of this study was to quantify various chemical and physical properties of DDGS, Distillers Wet Grains (DWG), and Distillers Dried Grain (DDG) from several plants …

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

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, …
