    Yeast is the main bacteria that are commonly used, and stinky tofu is no exception.

    As for its hygiene, of course, it should be eaten as soon as possible after opening a bottle, otherwise after a long time, other bacteria in the air will multiply on the stinky tofu, which will also produce a more unpleasant odor, and will produce toxins, so you can't eat it.

    As for the taste of stinky tofu, everyone's feelings are different, and most people's feelings are the same as what the landlord said: smelling stinky and eating fragrant. But there are also people who don't think it's fragrant anyway, and the landlord belongs to such people.

    There are also people who don't mind eating and smelling it, such as myself, hehe.

    There is a kind of toadstool called "Clostridium botulinum", which often multiplies with the production of stinky tofu, especially the local method, which generally divides pieces of tofu into several small pieces after cooking, and then places them in a container layer by layer, and then seals the seal. At this time, if it is sealed airtightly, it will cause a catastrophe: this "Clostridium botulinum" will take the opportunity to multiply.

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

    It is recommended that if you want to eat stinky tofu, it is best to buy it from a regular manufacturer; But don't eat more, because the reason why stinky tofu stinks is that its smell will have protein spoilage amines, which can react with nitrite to form 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 blocks the production of nitrosamines.

    Stinky tofu is a soy product and is rich in nutrients. Using high-quality soybeans as raw materials, the production process is more complicated. Soybeans go through ten processes, including screening, hulling, soaking, grinding, filtration, boiling, pulping, molding, scribing, and fermentation. Chenggong stinky tofu has a soft and smooth texture and exudes a peculiar fragrance.

    2. Stinky tofu smells stinky because in the process of fermentation, flooding and post-fermentation, the protein contained in it is decomposed under the action of protease, and the sulfur amino acids contained in it are also fully hydrolyzed to produce a compound called hydrogen sulfide (H2S), which has a pungent odor. That's why stinky tofu smells bad.

    From the perspective of traditional food, stinky tofu is a fermented product of beans like other soy products (such as soybean paste, tempeh, and various kinds of bean curd), which is a traditional food made by fermentation after inoculating with mold. After the action of microorganisms, this kind of food produces a variety of special aromatic organic acids, alcohols, fats, amino acids, etc., which are easy to digest and absorb, and also increase the content of vitamin B12. Vitamin B12 has the effect of promoting human hematopoiesis, which is very small in general foods.

    However, now, due to the interests of some people, regardless of 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 color, and with other odorous substances, it can become stinky tofu. This is quite dangerous, too much iron is very bad for the human liver, and its odorous substance may be caused by the decay of proteins, so it is possible that it is carcinogenic.

After ingestion and absorption of the toxin, the nervous system is damaged, causing symptoms such as dizziness, difficulty breathing, and muscle weakness.

    Stinky tofu is a street snack, and the production of unqualified stinky tofu is made using chemicals such as ferrous sulfate, which has a certain carcinogenic effect. Moreover, stinky tofu is too high in iron, which is not good for the body, especially the liver, which will increase the burden on the liver and slow down the metabolism of the liver.

    There is also unnaturally fermented stinky tofu that will produce proteins and produce carcinogenic harmful substances, such as botulinum toxin contamination, which may also cause botulinum toxin poisoning and even fatal danger.

    Some oils that are repeatedly used or oxidized in the processing of stinky tofu will produce some carcinogens such as heterocyclic amines and polycyclic aromatic hydrocarbons.

    Therefore, if you often eat stinky tofu, it may cause great harm to some livers in the body, and there are many carcinogens in stinky tofu, so it is recommended that you must pay attention to eating less stinky tofu as much as possible.

    Stinky tofu is made after a series of treatments such as fermentation and soaking in brine, such as fermented stinky tofu, which is fermented by microorganisms such as mold and lactic acid bacteria, and the smell mainly comes from sulfide and indole produced by microbial fermentation of proteins.

    Salt water immersion In the summer, a small amount of table salt is added to the boiled water that is boiled cold. Once the salt has melted completely, soak the fresh tofu in water in dilute salt water. Note that boiled water should not exceed tofu, that is, tofu should be immersed in water.

    Then put the salted water and tofu in the refrigerator. In this way, tofu can be preserved for at least three days.

    Cooking method Steam the washed tofu on the steamer for about 2 minutes, remove the tofu and cool it before storing it in the shade or refrigerator. After a few days, the taste of the tofu is still fresh.

    It smells bad and tastes good, which is the biggest feature of stinky tofu. When it comes to stinky tofu, most people think that stinky tofu is an unhealthy food, and that's because there are many "incriminating evidence" of stinky tofu. Specifically, the hazards of stinky tofu are as follows:

    1. The production process of stinky tofu is relatively complex, and it must go through several processes such as frying, marinating and fermentation. The whole production process must be carried out under natural conditions all the time, and the requirements for temperature and humidity are also very high during production, once the control is not good, it may be contaminated by harmful bacteria, which will cause gastrointestinal diseases in the human body, and will also lead to the multiplication of Clostridium botulinum in large numbers.

    Clostridium botulinum is extremely virulent, and after eating stinky tofu with this toadstool, you may experience symptoms of poisoning such as general weakness, headache, loss of appetite, and blurred vision. This germ often multiplies with the production of stinky tofu. In particular, in the local method, the tofu is generally cooked and divided into several small pieces, and then placed in a container layer by layer, and then sealed.

    At this time, if it is sealed airtightly, Clostridium botulinum will take the opportunity to multiply.

    2. Studies have proved that amines such as methylamine, putrescine, tryptamine and hydrogen sulfide will be produced during the fermentation process of soy products. Among them, if the amine substance is stored for a long time, it may also react with nitrite to form nitrosamines, a strong carcinogen.

    3. Due to the complexity of the production process of stinky tofu, many people use chemical means to make stinky tofu in order to save trouble. For example, using ferrous sulfate to dye tofu black, etc. These substances are harmful to the human body and not beneficial.

    Of course, stinky tofu is not useless, but if you want to eat stinky tofu, you should pay attention to buying regular stinky tofu and control the amount of food.
