Stinky tofu: Stinky tofu is easily contaminated by microorganisms during fermentation, and at the same time, it will volatilize a lot of basic nitrogen.

It is not easy to eat more!

Smells bad and tastes good, which is the characteristic of stinky tofu. Old people often eat stinky tofu, which can increase appetite and play a role in disease prevention and health care.

It was found that the B vitamins in tofu fermented by edible mold increased greatly, which was beneficial to the prevention and treatment of B vitamin deficiency. Because soybean contains substances that inhibit nitrosamine synthesis, it also has a preventive effect on cancer.

Besides meat, eggs, milk, fish, shrimp and other animal foods contain more vitamin B 12, fermented bean products can also produce a lot of vitamin B 12. Lack of vitamin B 12 will accelerate the process of brain aging and cause Alzheimer's disease. Eating stinky tofu regularly can prevent Alzheimer's disease.

Here is a way to eat stinky tofu, called meat pie stinky tofu. Use a proper amount of fresh minced meat, add a little seasoning such as yellow wine, refined salt, sugar, monosodium glutamate, etc., mix into cakes and spread them at the bottom of the bowl, then cut the whole stinky tofu into four pieces, spread them evenly on the patties, sprinkle a little minced onion and ginger, and steam on the pot for 20 minutes, which is both meat and vegetables and has more nutritional value.

But there is another saying:

Stinky tofu is delicious, but you must be careful of stinky tofu poisoning when you eat it with relish.

There used to be a kind of poisonous bacteria called Botox, which often multiplied with the production of stinky tofu, especially the indigenous method. Generally, the tofu block is cooked and divided into several small pieces, then placed in a container layer by layer and then sealed. At this time, if it is sealed tightly, it will cause catastrophe: this "Botox" will take the opportunity to breed.

After eating such stinky tofu, there will be poisoning symptoms such as general weakness, headache, loss of appetite and blurred vision.

From the point of view of traditional food, stinky tofu, like other bean products (such as soybean paste, fermented soybean, all kinds of fermented bean curd), is a traditional food fermented by inoculating mold. This kind of food is easily digested and absorbed by microorganisms, such as organic acids, alcohols, fats, amino acids, etc., and it also increases the content of vitamin B 12. Vitamin B 12 has the function of promoting human hematopoiesis, which is rarely contained in general food.

But at present, because some people are obsessed with interests and ignore the interests and health of consumers, they have changed the traditional production methods and adopted some chemical methods to simulate stinky tofu. If ferrous sulfate is used, it can produce black, and together with other odorous substances, it can become stinky tofu. This is quite dangerous. Too much iron does great harm to human liver. Its smell may be caused by corruption in protein, so it may be said that it is carcinogenic.

There is no denying that its smell will contain protein's corrupt substances-amines, which can react with nitrite to generate nitrosamines (strong carcinogens); When eating stinky tofu, it is best to eat more fresh vegetables and fruits, because fresh vegetables and fruits are rich in vitamins, especially vitamin C, which can block the generation of nitrosamines.
