Bioethanol: Testing for Saccharide Contamination

Efficient fermentation (the conversion of sugars to ethanol) is critical to the success of bulk fuel ethanol producers. Optimized fermentation leads to increased ethanol yields and profitability. Residual sugars left unfermented not only lower ethanol concentration, they also damage automotive engine components. Consequently, bulk fuel ethanol producers continually monitor the fermentation broth for the presence of unfermented sugars, also known as saccharides.
