PURPOSE:To prepare a freezable fermented food, by preliminarily fermenting a mixture of beans, grains, etc., adjusting the pH and the water-content of the mixture to specific levels under heating, inoculating a microbial strain belonging to Rhizopus genus, and fermenting the mixture. CONSTITUTION:Beans, grains, nuts, or their mixture are ground with a grinder, etc., added with water, and boiled. After discharging the water, the boiled beans, etc. are washed with water, added again with water, and subjected to the preliminary fermentation. The product is heated again, and the pH is adjusted to 3.0-7.5 during the heating process. As an alternative method, the preliminary fermentation is omitted, and the boiled beans, etc. is adjusted to the above pH range with an acid during the heating process. The water-content of the product is adjusted to 30-75% either by removing water or by adding water to the product. The objective fermented food can be prepared by inoculating a microbial strain belonging to Rhizopus genus [e.g. Rhizopus oryzae (IFO 4746) excluding Rhizopus oligosporus] and fermenting at 20-40 deg.C. |
