Patent-family-89663174

The present invention relates to a process for reducing syrup viscosity at the backend of a process for producing a fermentation product (e.g., ethanol from corn), comprising adding an oxidoreductase after the fermenting step, before whole stillage is subject to separation, to decrease the quantity of particles in the thin stillage by increasing the size of 5 particles in the whole stillage, thereby reducing the viscosity of syrup produced by evaporating the thin stillage.
