Abstract:
A method for producing raw sugar and ethanol which includes the steps of: heating and clarifying a plant origin sugar juice; concentrating the clear sugar juice so that the Brix value of the clear sugar juice is 15 to 50%; cooling the syrup to a fermentation temperature; fermenting the syrup, thereby selectively converting the saccharide components other than sucrose in the syrup into ethanol; and concentrating the fermented solution.
