Koji is prepared by adding koji mold to steamed grains (rice, barley,soybeans, etc.).It is then carefully cultured in warm, humid conditions that promotepropagation.Koji mold spores are just 3 to 10 μｍ (micrometers) in size.* 1 μｍ = 0.001mm.
Koji mold is certified as the "National Mold" of Japan!
In 2006, the Brewing Society of Japan designated koji as "a valuable asset carefully nurtured and used by our ancestors," and certified koji as Japan's "national mold". Ancient people recognized koji mold from among various molds as valuable, and used it for miso, soy sauce, Japanese sake, etc.
Types of Aspergillus
Rice Miso
(Aspergillus oryzae, Aspergillus sojae)
Mainly used in the production of miso, soy sauce, and refined sake. The spores are yellow, light green, or yellowish brown.
White koji mold
(Aspergillus kawachii)
Mainly used in the production of shochu. The spores are brown.
Black koji mold
(Aspergillus iuchuensis)
Mainly used in the production of “awamori” (Okinawa liquor). The spores are blackish brown.
Red koji mold
(Monascus genus)
Used in the production of tofu-yo, Chinese red wine, and Shaoxing wine. This mold produces bright red koji.
Bonito mold
(Aspergillus glaucus)
Use in the production of katsuobushi (dried bonito). This mold absorbs residue moisture from the katsuobushi, produces umami components, and breaks down fats and oils.

How to make rice koji
What are Enzymes?
IKoji contains many enzymes. The role of enzymes is to break down the nutrition in food, and aid in digestion and absorption. They also help in converting absorbed nutrition into energy. Koji is said to contain more than 30 types of enzymes including amylase, protease, lipase, and pectinase. Koji is a treasure trove of enzymes. Since it can generate vitamins beneficial for women and aids in digestion, it has gained popularity in the beauty and health fields.
Enzyme of Koji and its function
Breaking DownNutrients
Enzymes break down nutrients so they can be easily digested and absorbed. They create amino acids that produce umami, and aids in the tenderizing of food.
Aids Digestion
Amylases found in koji breaks down starch into glucose, and proteases break down protein into amino acids. Foods are eaten after the nutrients have been partially broken down by the enzymes, so nutrients are easily digested and absorbed in the body.
Drink Lactic AcidBacteriafor Energy!
Good bacteria, such as lactic acid, love
the oligosaccharides and dietary fiber*
produced by koji enzymes. They
consume these substances and
produce more good bacteria.
*Dietary fiber is a component originally
found in the koji.
Vitamin Production
As the bacteria metabolizes, it releases vitamins necessary for skin metabolism, such as vitamin B1, B2, B6, niacin, biotin, pantothenic acid, and inositol.
Why does koji make meat tender?
The pressure required to cut pieces of chicken, beef, and pork that have been marinated in shio koji for 30 minutes at 86F was measured using a stress rupture test. Compared to meat that had not been marinated in shio koji, the pressure required to cut the chicken and beef was 38% less, and 18% less for pork.
* Stress rupture test ... Measurement of pressure needed to cut meat.
Fluffy Marinated Fish
Approx. 1 tbsp. per slice of fish
Lightly coat the fish with shio koji, and
let marinate for 30 minutes to
overnight. Lightly wipe off the shio koji
before cooking.
Tender and Juicy Meat
Approx. 10g per 3.5 ounce of meat
Lightly coat the meat with shio koji, and
let marinate for 20 to 30 minutes.
Lightly wipe off the shio koji before
cooking.
Rub Vegetables with Kojifor Quick Pickles
1 to 2 tbsp. per 3.5 ounce of vegetables
For cucumber pickles, rub koji all over
the cut vegetable for approx. 15
minutes.
Shio koji burn easily.
Carefully wipe off the koji grains, and cook over low heat to prevent burning.
