Cultures for Natto (Kin)

Characteristic white strands of protein and polysaccharides in Natto


Natto (納豆) is a traditional Japanese food made from soy beans that have been fermented with Bacillus subtilis var. natto. It is often served as a breakfast food together served with Japanese mustard, soy sauce, and spring onions over rice. Traditionally, natto was made by wrapping boiled soybeans in rice straw, which naturally contains the bacteria Bacillus subtilis on its surface. 
Doing so allowed the bacteria to ferment the sugars present in the beans, eventually producing natto. Natto is often considered an acquired taste because of its strong flavor and sticky, viscous texture.
Our friends in Japan love it as it is slurp-worthy in rice and noodles, but did you know that viscous foods containing polysaccharides and produced by gut bacteria  minimize infections and could potentially ward of cancer?
Consumers in Japan also believe it can ward off pneumonia from the COVID-19 virus (unproven)! Love it or not, Natto is a superfood consumed for its health benefits and are more nutritious than regular unfermented soy beans:
