BROOKINGS, S.D. (AP)--South Dakota State University researchers are trying to turn a byproduct of ethanol production into a flour rich in fiber and protein.
The researchers are working with dried distillers grains, which typically are used for cattle feed. The process they're trying to perfect involves washing the grain, grinding it into powder, sterilizing it, heating it in a vacuum and removing its color, taste and smell.
Graduate student Sowmya Arra says if it works, it could help feed the world.
South Dakota Corn Growers director Lisa Richardson says that group also has looked into the possibility of turning distillers grains into flour. She says the group thinks the livestock market is likely to be more profitable, and that there are other questions including the potential market for the flour.
