As an approach to the computer control of sake-making, an on-line measuring system for ethanol and sake meter in the mash were used, and powdered α-rice was used in the fermentation.1. Ethanol was measured by a tubing-sensor system using porous teflon tubin. The sake-meter was calculated from the density which was measured by an automatic density meter (Yokokawa-Hokushin Electric Co. Ltd., DM61). The on-line data analysed by a personal computer agreed well with the experimentally measured ones during the whole mashing period.2. The powdered α-rice had a big initial dissolution rate, and it was feasible to control the sake-meter in the mash. The mashing process, dissolution of materials, and production of ethanol, was simulated, using a fermentation model. The simulated data agreed with the observed ones, and suggested the feasibility of the powdered α-rice.
