Technical Abstract: About 4 million tons of corn fiber are produced each year by current wet milling operations in North America (Renewable Fuels Association, 2003). All of the corn fiber currently produced is mixed with steepwater solids to produce "corn gluten feed" (CGF), a 19% protein animal feed that is high in fiber. CGF currently sells for about $0.03 per pound and is mostly included in ruminant rations. Current dry-grind ethanol plants are now producing more than 1 million additional tons (Renewable Fuels Association, 2003) of corn fiber, contained in the coproduct, Distiller's Dried Grains with Solubles (DDGS). New processes in development for modified dry grind operations, biobased product manufacture, and new enzymatic milling processes, will generate more and different types of fiber in the future. Rather than treating this fibrous material as the lowest value byproduct from corn milling, our research program has chosen to look at fiber as one of our most abundant, and currently available and as a renewable feedstock for the production of biobased industrial products, nutraceuticals, functional food ingredients, and biofuels. Examples of potential products derived from fiber include corn fiber gum, corn fiber oil, L-arabinose, polyamine conjugates, cellulose/arabinoxylan products and fuel ethanol.
