Sequential Extraction could get more value from a bushel of corn

This story is about sequential extraction--a method of extracting valuable proteins and other useful substances from corn kernels in which the ethanol is extracted as a by-product of the extraction of these potentially more valuable substances. This makes a lot of economic and environmental sense if they can make it work. -- Jeff Goettemoeller
Sequential Extraction Process Could Provide Many High-Value Ethanol Co-Products: Iowa State Professor: "'You have to think like a protein company,' Johnson said. 'Ethanol becomes a co-product. Zein is more valuable on a per pound basis. Oil is more valuable on a per pound basis. The other food-grade protein fraction is more valuable. We envision that being used for food purposes for human consumption.'"
