What temperature do you dehydrate koji?

Your koji is ready for use immediately! We recommend using koji while it’s fresh. Alternatively, you can freeze it (after bringing it down to room temperature first and then chilling it in the fridge) for up to 6 months or dehydrate it at 95 F or below for longer term storage.

Make sure the internal temperature of the rice is at 165F or higher. If unsure, use a food thermometer.

To propagate koji from these rice, the easiest method is to blend or grind the rice and sieve the powdered koji rice onto fresh rice. 1g of koji spores should be enough to inoculate 1kg of rice. In Japan, koji is typically cultivated in cedar trays which are never washed and constantly reused.

Can you eat Koji? Koji can be eaten raw, but is at it’s best when added to other ingredients to create an umami flavour in the food.

Though it is possible to culture koji without a starter, it can be challenging for beginners to determine whether the cultured mold is the right species. If this is your first time making koji culture, it is safer to purchase a koji culture starter and get a feel for the mold before collecting your own spores.

Parboiling happens when you soak, steam, and dry rice while it’s still in its inedible outer husk. This turns the rice inside a slightly yellow hue. Parboiling rice makes it easier to remove the husk of the rice before eating it.

Use rice koji immediately, refrigerate or freeze in a sealed container, or slowly dry for 1-2 days for longer-term storage. Refrigerated koji will keep for 2-4 weeks, dry koji for 3-6 months, and frozen koji for up to 1 year.

Place in a steamer filled with cold water (the water should not be boiling when the rice is placed into the steamer). Turn on the heat to high, cover, and cook for 20 minutes. Turn off the heat, and let the rice sit in the steamer with the lid on for at least 5 more minutes.

If the incubation temperature is too low, the spores may take longer to colonize the rice, allowing the bad microbes to settle in first. On the other hand, if the temperature exceeds 35C (95F) for too long, the koji mould could die.

Koji is an aerobic mold, meaning oxygen must be available for it to colonize a substrate. Most incubators consist of an insulated box that controls the temperature and humidity via external devices. You’ll need to keep the temperatures between 80 and 95 degrees Fahrenheit, and the humidity around 85 to 90 percent.

Making miso without using koji malt So, traditionally, village people do not use koji to make miso in these villages. Instead of koji, they make misodama (miso ball) to harvest natural fungi in the room. This method can be seen Tohoku, or Shinshu areas, with heavy snow and earth oven in their houses.

Wrap the koji-rice mixture with the cloth tightly and incubate the mixture at 32-35C for 18-22 hrs. Having a bowl of water in the incubator ensures that the koji-rice does not dry out while fermenting. Wipe away any condensation on the lid to avoid water dripping onto the koji.

Do not leave rice to cool down in the rice cooker, steamer or pan. Once cooled to room temperature, cover the rice and store in the refrigerator at 8oC or below (preferably below 5oC). Only reheat rice if it has previously been cooled down safely and kept in the fridge until needed.

Is Koji Healthy? Like other fermented foods, it possesses a number of powerful health benefits. In particular, it acts as a great source of probiotics, a type of beneficial bacteria that helps improve gut health and enhance nutrient absorption.

For fresh koji at room temperature, you want to use it within the day you make it. It’s fine refrigerated for about a week, but if you want to keep it longer than that, you can freeze it, and it keeps for a pretty long time, about six months to a year. You can also dry it.
