And Koji Culture

Koji culture is a starter culture made from a grain, typically rice or soybeans, that has been inoculated with the mold Aspergillus oryzae. This mold is a key ingredient in the fermentation of many traditional East Asian foods. The mold breaks down starches and proteins into sugars and amino acids, creating unique flavors and aromas.

Koji is used as a fermentation starter for products like soy sauce, miso, sake, and rice vinegar. It acts as a natural flavor enhancer, tenderizer, and can contribute to the umami taste in foods. It is most commonly found in fermented sauces and pastes, particularly those with an Asian or ethnic profile.

Koji culture is generally recognized as safe (GRAS) by the FDA for use in food. It is a natural product of fermentation and is a staple in many diets. Regulatory bodies like EFSA have evaluated fermentation processes and ingredients. While generally considered safe, like any fermented food, it can be a source of beneficial compounds.
