PURPOSE: Rice unsuitable for making SAKE such as long-stored rice is made into a pure rice starch, which is made using a liquefying enzyme into liquefied starch to remove the odor of old-stored rice, thus making SAKE utilizing rice unsuitable for making sake.

CONSTITUTION: Long-stored rice, crushed rice or unripen rice or other rice unsuitable for making SAKE is used to collect starch by removing proteins and other foreign substances therefrom. A liquefying amylase is made to act on the collected starch to prepare liquefied rice starch. Separately, rice for making SAKE of 75W85% polishing grade is used as a raw material to prepare MOROMI (fermentation mash) and the above liquefied starch is added by 10W 50% based on the rice for making SAKE before or after RYUTEN to produce SAKE.
