What is Japanese Koji Rice?

Koji rice is steamed rice inoculated with the Aspergillus oryzae fungus. It is used to make miso, Shio Koji, Amazake etc. by fermentation. This product is a dried version.

Aspergillus oryzae is a fungus whose enzymes (amylases, lipases, proteases, pectinases) convert starch into sugar and proteins into amino acids during the fermentation process. Converting starch into sugar creates sweetness. The breakdown of proteins leads to the famous umami taste.



Use of Koji Rice

This dried koji rice is a kind of starter culture for various fermented products. The fermentation can result in miso if, for example, soybeans, salt and water are added.

Mixed with salt and water and short-time fermentation you get Shio Koji, an ingredient that was rediscovered a few years ago in Japan as a marinade for softening vegetables and fish, but also as an ingredient in sauces. Shio Koji can be enriched with other ingredients such as soy sauces, which in this combination results in a very umami-rich product.
