What is lobster sauce?
Douchi is a traditional condiment for fermented bean products in China. Douchi is made by using black beans or soybeans as the main raw materials, decomposing soybean protein with Mucor, Aspergillus or bacterial protease, adding salt, wine and drying to inhibit the activity of enzymes and delay the fermentation process.

There are many kinds of lobster sauce, which can be divided into black lobster sauce and yellow lobster sauce according to processing raw materials, and salty lobster sauce, light lobster sauce, dry lobster sauce and water lobster sauce according to taste.

According to records, the production of Douchi was first spread in Taihe County, Jiangxi Province, and then spread overseas through continuous development and improvement. The Japanese once called lobster sauce "Nachi", and later referred to sugar natto invented in Japan. Douchi is also widely eaten in Southeast Asian countries, but it is not so popular in Europe and America.

Extended data:

1, Douchi is a fermented food, which contains protein, calcium, phosphorus, iron, cobalt, selenium, molybdenum, thiamine, riboflavin, nicotinic acid and so on, and is extremely rich in nutrition. Douchi is a "longevity bean" for the elderly. Regular consumption can not only stimulate appetite and digestion, dispel wind and cold, but also prevent cerebral thrombosis.

2. Douchi can stimulate appetite and digestion, dispel wind and cold, and treat acclimatization. In recent years, it has been found that the cobalt content in douchi is 40 times that of wheat, which has a good effect on preventing coronary heart disease. In addition, Douchi can also improve the blood flow of the brain and effectively prevent the formation of cerebral thrombosis.

3. Douchi is good, but the elderly can't eat more, and it is appropriate to eat less than 50 grams a day. A lot of salt will be added in the processing of douchi. If lobster sauce is added to the dishes, the amount of salt should be reduced to avoid excessive salt intake.
