More details on typical manufacturing processes can be found elswhere in the ethanol manufacturing process (Figure ). There would appear to be numerous variables that could influence the production of EC such as substrates, heat, yeast source, fermenting time, etc. After distillation of the ethanol when whole stillage is processed (centrifuged) to distillers grains co-products plus thin stillage, the evaporation process of thin stillage to produce the condensed distillers soubles (CDS) may have a variable amount of EC present. Additionally, the amount of CDS added back into the WDGS and DDGS will determine the amount of EC present in the livestock feed products. Milo (sorghum) WDGS appears to have lower EC content. It is not known why or if this is a consistent finding. Though one sample was significantly higher this may have been due to corn CDS being added back into the milo WDGS (personal communication with the sorghum industry).
