Homemade natto

Introduction:

"Natto is a very healthy food, suitable for all ages. In fact, it's very easy to make natto at home. Let's have a look!"

Production steps:

Step 1: first, wash the soybean and soak it in water for 12 hours. Add 2G sugar and 1g monosodium glutamate to the soaked soybeans, mix them well and steam them thoroughly in the pressure cooker. I use the beans from the electric pressure cooker.

Step 2: take out the steamed soybeans and cool them to about 45 ℃, then inoculate them with natto

Step 3: take out natto capsule

Step 4: open natto capsule, pick out 1 mm * 1 mm natto powder with toothpick, and mix it with 2 ml purified water to form bacteria liquid

Step 5: mix the bacteria liquid with the steamed soybeans and start fermentation. I use the natto machine. If there is no natto machine, I can use a breathable container covered with a layer of gauze to ferment in a warm environment

Step 6: the temperature is high in this season, and the first fermentation is completed after 10 hours. You can see a white film on the surface of soybean. Stir the soybean with a spoon to see the obvious silk drawing, and you can smell the aroma of fermented soybean.

Step 7: the first fermented natto should be put in the refrigerator for secondary fermentation for 12 hours. Find a clean large container, seal the bowl with plastic film, and then prick some small holes on the plastic film with toothpick (to provide oxygen for secondary fermentation, natto bacteria are nutritious bacteria)

Step 8: after the second fermentation, the white film on the surface of natto becomes transparent, the drawing is more obvious, and you can obviously feel that the drawing becomes very strong! Then you can find a sealed container to keep it. You can take it when you eat it. It can be kept for about a week.

Note: natto is a very good beauty and health products, but also when eating skills Oh! Nattokinase, which plays a role in natto, will be inactivated in acidic environment, so try not to eat it on an empty stomach to prevent gastric acid from damaging it. In addition, try not to heat it to ensure the best health care effect
