What Fermentation Process Is Used For Miso? (Solved)

Miso manufacturing is a two-stage fermentation process in which a mold, such as Aspergillus oryzae, is inoculated onto a substrate to produce koji, and then the koji is fermented. When the koji is added to a salt and soybean mash, a second fermentation starts, this time including bacteria and yeast, and the miso is allowed to ferment for up to two years.

  • Fermentation is a process that takes place in a fermentation vessel. Miso is made by fermenting a starter called koji, which is often comprised of the fungal microbe Aspergillus oryzae, however it is also possible to make miso using other cultures, such as a yeast known as Saccharomyces rouxii.

What is koji fermentation?

When cooked rice and/or soya beans are infected with the fermentation culture Aspergillus oryzae, the result is a dish known as Koji. It is utilized in the preparation of popular dishes such as soy sauce, miso, mirin, and sake. The preparation of the koji is the initial stage in the production of these items.

How is barley miso made?

Mild Barley Miso is a dark barley miso that is produced from soy and barley and seasoned with sea salt to taste. It goes through a traditional fermenting process that lasts between 12 and 20 months.

You can’t create miso unless you have koji. Miso is not a fermentation in the traditional sense; rather, it is made from enzymes produced by the mold Aspergillus oryzae, which is cultivated on rice to produce koji. Those enzymes are utilized to break down the proteins and starches found in soybeans, which results in the production of miso.
