Fermentation in Dried Fish

Mold fermentation breaks down fish fat and removes moisture. This creates a complex aged aroma like cheese.

Fermentation in Dried Fish

Core Concept

Fermentation transforms fish protein and fat into pure umami and aged aroma.

Did You Know?

The fish becomes as hard as wood. It is one of the hardest foods in the world.

How mold changes the fish

Mold grows on the dried bonito. It pulls water out from deep inside. This dries the fish completely.

Building the cheese aroma

The mold also breaks down fish fats. It turns them into new flavor compounds. These smell exactly like aged parmesan cheese.

Ryota says:

Standard katsuobushi skips this mold step. It smells smokier and much sharper.
