Interpretive Summary:

Technical Abstract: Distiller’s grains and syrup are byproducts from ethanol dry mill processing. Ethanol production is increasing in Midwestern states and thus the availability of byproducts is also increasing. Confusion currently exists in industrial nomenclature regarding “solubles” in these materials. In our study, we considered dissolved solids as “solubles”, and developed a methodology to determine the soluble percentage in dried distillers' grains with solubles as well as in syrup. Mass balance method was initially used to determine the soluble content in these materials. The results from this method were not in good agreement with experimental data, however. This led to the development of a new method for determining the soluble percentage in distillers' grains and syrup, with results exhibiting R2 > 0.95.
