In a process for producing koji which comprises inoculating a koji mold in a modified koji substrate and cultivating it at a temperature of 20 DEG to 40 DEG C. for a time sufficient to produce koji, the improvement wherein the cultivation is carried out in the presence of 0.05 to 8% by weight, based on the total weight of the unmodified koji substrate, of a sodium or potassium salt of an aliphatic carboxylic acid containing up to 4 carbon atoms. The improved process makes it possible to inhibit bacterial contamination of the cultivation system, and provides good quality koji which exhibits high ratios of nitrogen and sugar utilization in the manufacture of fermented food products such as soy sauce, miso and mirin. |
