Soy sauce is a seasoning commonly used in our daily life. It is often used in cooking. However, as people's health awareness becomes stronger and stronger, many people also find that soy sauce also has certain risks.
Because some health programs mentioned that if you often eat foods containing sodium benzoate, you will increase the risk of cancer, and some soy sauces we usually use contain sodium benzoate.
01
Sodium benzoate is a kind of preservative, which is also widely found in nature. For example, we often see prunes, cinnamon, cloves and other items that contain this substance.
If you want 100 formic acid to play a role, you need to be in a state of no dissociation, and if you want to maintain a dissociated state, you need corresponding acidic conditions. The data shows that the most suitable pH value of sodium benzoate is 2.5~4.
Undissociated sodium benzoate has relatively strong lipophilicity, which allows sodium benzoate to enter the cell through the cell membrane smoothly, and will interfere with the permeability of the cell membrane of some microorganisms such as mold and bacteria.
When the permeability of microbial cell membranes decreases, the ability to absorb amino acids will gradually decrease, and the benzoic acid molecules entering the cells can also acidify the cells, which will inhibit the activity of respiratory enzymes in microbial cells and play a role in anti- corrosion Effect.
Through relevant data research, it is found that if the intake of sodium benzoate is less than 0.5mg/kg, it will not cause any harm to humans and animals.
When sodium benzoate enters the stomach, it will be converted into benzoic acid under the diversion of gastric acid. This substance is toxic to a certain extent. According to animal experiments, it can be found that if mice take sodium benzoate for a long time, they will lose weight. Phenomena, accompanied by diarrhea, bleeding and even death.
Under normal circumstances, if a person's weight is 70 kg, then there will be corresponding problems with a one-time intake of 35 grams of sodium benzoate, and under normal circumstances, the content of food additives is very small.
The capacity of a bottle of soy sauce is about 500 ml, but the content of sodium benzoate is only 0.5 grams , so it takes 70 bottles of soy sauce to pose a threat.

Are food additives really useless? the truth is coming
When many people talk about food additives, they think it is very scary, and they think it will cause great harm to the body, and negative news about food additives has always been very common.
The reason why food additives appear is because consumers have needs in this regard. Many people like to eat food that is very beautiful, fresh, tasty and nutritious. It contains a lot of ingredients, and the output is very large . , it will deteriorate without anti-corrosion treatment.
Or there will be a great shortage of vegetables and fruits, and additives can prevent this situation. Food additives have made the food industry, and there are various packaged foods in supermarkets.
Under normal circumstances, if food additives are added in accordance with the relevant national standards, there will be no harm to the body, because under the current circumstances, we cannot avoid the intake of food additives.
It is undeniable that food additives will indeed bring some safety hazards to the body, because everyone's physical condition is different, and excessive intake of food additives will also cause harm to the body.
What kind of harm will it cause to the human body has not been done very authoritative research, so the answer is not clear. When we usually buy food, we try to choose some food with fewer additives, which is better for the body.
The reason why there are many food safety incidents is that many cases are actually caused by the use of illegal food additives, such as clenbuterol and melamine. These additives are illegal, but because many businesses want to earn high profits , so this additive was chosen.
