Some scientists believe that it was used earlier than 206 BC. The touchi products were found in the western Hunan province.

In the tombs where the Han dynasty artefacts were also left. The use of douchi further spread in other parts of Asia like Japan, Malaysia and Philippines.

The douchi was produced by either straining the fungal or bacteria. Currently, douchi is made by the normal and natural fermentation.

Douchi could be salted or unsalted where the unsalted douchi was used for medicinal purposes according to Li shih chen.

  • Depending on the taste you are reaching for you may soaking the fermented beans for 1/2hour before use. Fermented beans are salty, therefore soaking is necessary to reduce the excess salt. Nevertheless, some people will choose a brand that has reduced salt instead of soaking.
  • The common method of use is coarsely chopping or cutting it first before cooking.
  • You may sprinkle the fermented beans over food before cooking, mash it and use as wet rub on meat or seafood, make it as a sauce, or when frying add on your oil before the frying process begins.
  • Remember, they have a powerful flavour, therefore, you only use a small portion. To be precise, a tablespoon per recipe is fine.
  • Don’t add a lot of salt to the meal whenever you use the fermented beans. Because the condiment itself is extra salty.


The sauce is distinctly flavoured that substituting it with any other sauce is hard. Never confuse the fact that fermented black beans aren’t the regular black beans. Neither are they black turtle beans that are from Central and South America. In fact, you can’t use them as substitutes.

Though not an ultimate cut off best substitute, you may use soy sauce or black bean sauce and sometimes even soybeans work perfectly.


  • The fermented beans like other beans and sauces can last up to a year if stored properly. If you made yours at home ensure you store it in a sealed container and place it in a refrigerator. Alternatively, store it in a sealable fridge bag and into the fridge.
  • If you are buying your beans, keep them in a sealed container too. This will help the beans to avoid drying. Nonetheless, when you realize that your beans are beginning to dry up, add some neutral oil drops for them to regain the original texture.
  • There are those who don’t bother refrigerating the beans. This is mostly the case when you bought the beans in a cardboard container. They prefer to fold the container in a way that retains the odour within beans.


The fermented black beans help to lower the blood sugar levels which makes it suitable for those with diabetes. The beans help in the formation of insulin and the stimulation of the same to fight the low blood sugar.

It works to reduce hypertension (blood pressure in the arteries going too high). The effects of high blood pressure are dire and may include chest pain and difficulty in breathing. The sodium in the fermented beans can fight hypertension.

It’s an antioxidant. The antioxidant feature of the fermented black beans will help you reduce stress and fatigue. It will act as your great anti-aging product as well.

The fibre content of the beans helps your body with digestion. It cleans your stomach by absorbing any other non-digestive item that would otherwise stick in your intestine.

The fermented black beans contain good bacteria that help to reduce the body fat. The beans contain protein and fibre and if the body contains no excess carbs and sugars it gets easy to reduce fat. However, for you to realise the benefits, use the fermented beans with limitation.

Here’s to a great immunity booster. It has good bacteria’s in your system to fight diseases. Since most diseases come from your gut they are normally dealt with at the gut level. This reduces the chances of getting ill.

Other benefits of using fermented black beans include:

Fermentation acts as a preservation method which means your food has a longer shelf life. In the earlier years before the existence of refrigerator fermentation was the best way to make sure your food stayed longer.

Fermented foods like the black beans although loved in the Asian community are not appreciated globally as they should.

They are healthy, functional, therapeutic and yet the force of urbanization and civilization makes it hard to penetrate other markets.

You see even those who consume the fermented foods find them in stores or supermarkets but not making them at home. This means that the method of production is slowly getting altered.

This is the one way to maintain our traditional methods of cooking. Traditions practices give us a sense of belonging and there’s no better way to practice it than with the delicious meals.


With all the above said, you realize that you should start using the douchi to reap both the health benefits and flavors it adds to your meal. If you love to buy the ready prepped douchi then, in my opinion, go for yang jiang fermented beans.

They are the best because they feature soybeans from Yangjiang China.
