To understand what is natto food, it's essential to explore its production process. Natto is made by fermenting soybeans with a bacterium called Bacillus subtilis. The process begins with soaking and steaming soybeans until they’re soft. These are then inoculated with the bacteria and kept at a warm temperature for 24–48 hours to ferment.
In ancient times, this fermentation occurred naturally using rice straw, which contained the necessary bacteria. However, in modern production, the process is more controlled to ensure consistent quality. This fermentation results in natto’s characteristic stickiness and strong flavour.
