Title: RAW SUGAR AND ETHANOL PRODUCTION METHOD USING SELECTIVE FERMENTATION
Abstract:
The present invention addresses the issue of providing a raw sugar and ethanol production method whereby sucrose does not readily decompose during fermentation of a sugar solution, the raw sugar yield is high, and the ethanol yield is also high. A solution to said issue is a raw sugar and ethanol production method including: a step in which a plant-derived sugar solution is heated and refined; a step in which the refined sugar solution is condensed to a Brix value of 15-50%; a step in which the condensed sugar solution is cooled to fermentation temperature; a step in which the non-sucrose sugar content in the condensed sugar solution is selectively converted to ethanol by fermenting the condensed sugar solution; and a step in which the fermentation liquid is condensed.
