PURPOSE:To prepare a solid koji having low contamination of bacterium and high enzymatic titer, by sprinkling previously part of a carbohydrate raw material on the piling bottom plate of a production unit for koji, piling a solid koji raw material into which a mold is inoculated, preparing the koji. CONSTITUTION:Part of a carbohydrate raw material to be used in a solid koji raw material, for example, 0.1-25wt%, preferably 2-10wt% carbohydrate raw material is uniformly sprinkled on a piling bottom plate of a production unit for koji, a solid koji raw material inoculated with a mold, which is obtained by inoculating the mold into the solid koji raw material consisting of the remaining carbohydrate raw material and a protein raw material, is piled on the above-mentioned carbohydrate raw material, and koji is then prepared by a conventional procedure. |
