Effect Of Elusieve Fractionation On Physical Properties Of Distillers Dried Grains With Solubles (Ddgs), Kurt A. Rosentrater, Radhakrishnan Srinivasan Jun 2009

Effect Of Elusieve Fractionation On Physical Properties Of Distillers Dried Grains With Solubles (Ddgs), Kurt A. Rosentrater, Radhakrishnan Srinivasan

Kurt A. Rosentrater

The production of corn-based ethanol in the U.S. has been dramatically increasing in recent years, and consequently so has the quantity of coproduct materials generated from this processing sector. These streams are primarily utilized as livestock feed, and can partially offset the need for corn in feed rations. As the industry evolves, new technologies are being developed to improve the value proposition of the coproducts, especially distillers dried grains with solubles (DDGS). One of these is the Elusieve process, which combines sieving and air classification to accomplish fractionation of the DDGS into component-rich (i.e., protein, lipid, fiber) streams. Previous studies …

The production of corn-based ethanol in the U.S. has been dramatically increasing in recent years, and consequently so has the quantity of coproduct materials generated from this processing sector. These streams are primarily utilized as livestock feed, which partially offsets the need for corn in feed rations. Because of its use as an animal feed, considerable research has been conducted into the nutritional properties, and to some extent the physical properties, of commerciallyavailable distillers dried grains with solubles (DDGS). There are, however, occasions when the quality of coproducts is not consistent. Thus questions regarding the influence of production operations on …
