PROBLEM TO BE SOLVED: To provide a method for producing frozen fermented soybeans by which frozen fermented soybeans packaged in small-sized packets in a frozen state can be practically produced as qualified fermented soybeans.SOLUTION: The method for producing frozen fermented soybeans includes: longitudinally stacking a plurality of layers of steamed soybeans into which natto bacillus is inoculated, layer by layer via porous sheets fermenting the stacked steamed soybeans and maturing the fermented steamed soybeans followed by freezing the matured fermented soybeans. Frozen fermented soybeans frozen one by one are produced by putting apart the frozen soybeans produced by the method into granules each in a frozen state.COPYRIGHT: (C)2009,JPO&INPIT【課題】冷凍した状態で小分けされている冷凍納豆を実生産が可能な製造方法で、なおかつ、品質の良い納豆として提供する。【解決手段】納豆菌が植菌されている蒸煮大豆を、有孔のシートを介して一層ずつ上下に複数層積層し、発酵、熟成を行なった後、冷凍する冷凍納豆の製造方法。前記方法で製造した冷凍納豆を冷凍状態でほぐして一粒ずつ冷凍されている状態の冷凍納豆を製造する。【選択図】図1
