A process for producing concentrated shoyu which comprises adding and mixing a shoyu koji into the juice separated from a shoyu moromi in the early stage of brewing, used as a brewing water, and then carrying out fermentation and ageing according to the usual method.

Process for producing concentrated shoyu

In a method for producing a fermentation product which comprises inoculating a mold in a substrate and cultivating it, the improvement which comprises adding

Method of producing Koji products

An improved process for producing a salty seasoning by fermentation, wherein the improvement is characterized in that the feeding of raw materials, fermentation or ripening is carried out in the co-presence of potassium chloride and sodium chloride. As compared with the product obtained by a conventional process, the salty seasoning obtained by the above process has a better flavor and has a much lower sodium chloride content so that it is suitable for use in a low sodium diet.

Process for producing soy sauce or Miso

In a process for producing a solid koji for a fermented food product which comprises inoculating a koji mold in a modified koji substrate and cultivating it at a temperature of about 20.degree. C. to about 40.degree. C. for a time sufficient to produce a solid koji for fermented food products, the improvement wherein at a certain time during a period of about 10 hours to about 20 hours after the inoculation of the koji mold, the cultivation system is subjected to a drying treatment to adjust its water content to about 30.+-.5%.

Process for producing solid koji

In a process for producing koji for a fermented food product which comprises inoculating a koji mold in a modified koji substrate and cultivating it at a temperature of about 20.degree. C. to about 40.degree. C. for a time sufficient to produce koji for the fermented food product in the presence of a salt of an aliphatic carboxylic acid with up to 4 carbon atoms; the improvement wherein the cultivation is carried out in the presence of at least one added member selected from the group consisting of lactic acid bacteria and yeasts.

Process for producing koji for fermented food products

In a process for producing a fermented liquid food product by fermenting a moromi which comprises a koji for the fermented liquid food product, a moromi substrate and a liquid such as brine, alcohol and water at a temperature of about 10.degree. to about 40.degree. C for a time sufficient to produce the fermented liquid food product; the improvement wherein the fermentation is carried out in the presence of about 0.05 to about 10% by weight, based on the total weight of the koji and moromi substrate, of an added metal salt selected from the group consisting of potassium salts, sodium salts, calcium salts and magnesium salts of aliphatic carboxylic acids containing up to 4 carbon atoms.

Process for producing fermented liquid food products

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.degree. to 40.degree. 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.
