Improving the corn to ethanol fermentation process with near-infrared spectroscopy (NIRS)
17 Dec 2021In this white paper, Metrohm describes the capabilities of the modern analytical method near-infrared (NIR) spectroscopy for monitoring and improving the fermentation process of corn to ethanol. Analysis time of in-process fermentation samples is reduced from one hour to five minutes—nearly 90% Additional time savings by close monitoring of the fermentation process with NIRS also allows ethanol producers the ability to increase their manufacturing capacity by up to 10%.

Near Infrared SpectroscopyNear-infrared (NIR) spectroscopy measures the interaction of near-infrared light with a sample, including transmission, reflectance and absorbance, facilitating the identification of analytes. Measurements can be conducted using a Fourier-transform near infrared (FT-NIR) spectrometer, while there are also UV-Vis- NIR spectrophotometers that measure a broader spectrum of wavelengths.

Biological materials used include cells, enzymes and organisms. Usually bioprocessing requires a batch or continuous bioreactor such as a fermentor or cell culture system. The advantages of using a reactor include high productivity, easy configuration, adjustable values and automation.EthanolNIRS
