Abstract:
1. A method of producing a biofuel, the method comprising: a) compressing sugar beet plant material to provide a compressed plant material; b) vacuum extruding the compressed plant material wherein the vacuum extruding comprises subjecting the compressed plant material to a reduction in pressure of between about 3 kPa to about 100 kPa to produce an extruded brei; c) fermenting the extruded brei of b) to provide a fermented mixture; and d) producing said biofuel, wherein the biofuel is ethanol, wherein at least about 19% to about 25% more ethanol is produced compared to conventional sugar beet plant-to-ethanol processes, wherein the conventional plant-to-ethanol process is performed in the absence of a vacuum extruding step.
