Interpretive Summary:

Technical Abstract: Ethanol production is projected to increase through the next decade. Associated with this increase will be a proportionate increase in byproducts, including distillers dried grains with solubles (DDGS). Because of high fiber content and low market value, DDGS are normally included in ruminant animal diets. In order to increase its economical viability, the fuel ethanol industry is developing added-value from the byproducts and implementing new pre-fermentation fractionation technologies to improve process efficiencies and develop high-value co-products. Mycotoxin contamination of grain and byproducts is a major issue affecting both production and utilization. Limited data suggests that mycotoxins are concentrated three-fold in by-products of the conventional dry-grind ethanol production process. This concentrating effect severely limits using mycotoxin-contaminated DDGS in non-ruminant animal diets. This presentation will examine the effect of the dry fractionation processes on the distribution of mycotoxins in pre-fermentation co-products, including germ, bran and degermed, debranned corn (DDC).
