2. Put the tofu neatly on a clean steamer, and pay attention to a certain gap between the tofu. Cover it with a layer of gauze to prevent dust (or newspapers, straw, etc.), so that it can naturally ferment in the bad environment of about 15 degrees Celsius. When a layer of yellowish fimbriae grows on the surface of tofu, you can enter the next step. If the hair on the surface of tofu is black or green, it means that the production failed;

3. Preparation of bittern soup: Boil spices such as pepper, cinnamon, ginger, star anise and pepper with water, cool and pour some yellow wine.

What are the hazards of tofu milk?

1. Induced hypertension

Problems of salt content in sufu. A piece of10g sufu (calculated by the salt content of 6%) contains 0.6g of salt, which is not high. So as long as you eat reasonably, although it is not a big problem for ordinary normal people. But for people with high blood pressure, we should pay attention to the amount of tofu milk.

2. Increase the burden on the kidneys

Under normal circumstances, protein, a plant that people eat in the body, is metabolized, and most of it is finally decomposed into nitrogen waste, which is excreted by the kidneys.

However, the renal function of most elderly people has declined. If you eat a lot of tofu milk, a large amount of amine metabolic waste and sodium salt content will increase the burden on the kidneys.

3. Accelerate arteriosclerosis

Soybean products are rich in methionine, which can be converted into cysteine under the action of enzymes. Cysteine can damage endothelial cells in arterial wall, and it is easy to deposit cholesterol and triglyceride on arterial wall, thus promoting the formation of arteriosclerosis.

4. Lead to iodine deficiency diseases.

The beans in making tofu milk contain a substance called saponin, which can promote the excretion of iodine in human body. If you eat tofu milk in large quantities for a long time, it will lead to iodine deficiency.

5. Induce gout

Tofu milk contains more purines, and gout is a disease caused by purine metabolism disorder, which makes uric acid involved. Therefore, eating tofu milk for gout patients will aggravate the degree of gout.
