摘要

PURPOSE:To improve the utilization of the raw material for the brewing of Japanese sake, and to enable the brewing of high-quality sake having high alcoholic content and good body, by using gelatinized liquid of polished rice as the raw material. CONSTITUTION:Highly polished rice is crushed in the presence of water, and the resultant milky slurry is used as the refined rice for the brewing of Japanese sake. As an alternative method, rice is crushed in the presence of water, the resultant milky slurry is centrifuged, and the precipitate rich in rice starch is used as the refined rice. The refined rice is added with a heat-resistant alpha-amylase preparation without drying the rice, and heated at the optimum temperature of alpha-amylase to obtain gelatinized liquid of refined rice. The liquid is used as a raw material for the Japanese sake, and the whole amount of the liquid, the malted rice, and water is added to the yeast, and fermented to obtain the objective Japanese sake.
