Abstract
Abstract Producing koji for fermented food products by modifying an unmodified koji-substrate composed of a vegetable protein material and a vegetable carbohydrate material, inoculating a koji mold in the resulting modified koji-substrate, and cultivating it, wherein said cultivation is carried out in the presence of 0.1 to 1.2% by weight, based on the water content of the modified koji-substrate, of acetic acid added. This process is suitable for use in the manufacture of fermented foods such as soy sauce, miso, or sake.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
99 words
A process for producing koji for fermented food products which comprises inoculating a koji mold in a modified koji-substrate composed of a vegetable protein material and a vegetable carbohydrate material and selected from the group consisting of steamed koji-substrate, puffed koji-substrate and roasted koji-substrate, and cultivating the koji mold in the presence of 0.1 to 1.2% by weight, based on the water content of the modified koji-substrate of acetic acid at a pH of about 4 to 7.5, a temperature of about 20° to about 40° C and for a time sufficient to produce koji for fermented food products.
Claim 2
Dependent Claim
