You may be interested to know how grain quality affects ethanol production and DDGs. If so, then you would interested in Leland McKinney’s presentation at the Corn Utilization and Technology Conference, held recently in Atlanta. I spoke with him to learn about his research on this topic. Leland is Extension State Leader in the Dept. of Grain Science at Kansas State University.

To start with he says that getting information presented a challenge since there’s not a lot of it publicly available. So, without much data to work with he visited personally with industry representatives to find out their thoughts and put together an overview presentation on the subject. He says moisture and how it impacts grinding efficiency and water balance in an ethanol plant were mentioned as well as quality attributes like fermentable starch and test weight. When it comes to the DDGs he says mycotoxins came up frequently as a concern. The bottom line though is that research is needed on how grain quality effects the production of ethanol. Hopefully that will be done before another CUTC!
