What is Sodium Nitrite?
Sodium nitrite is a not natural substance with the chemical formula of NaNO 2. It is a white to yellowish crystalline powder, very soluble in water and hygroscopic. From a commercial perspective, it is one of the most essential nitrite. It is the precursor of a range of organic compounds, such as medications, dyes as well as pesticides, however it is most likely best known as a food additive used in processed meat as well as (in some countries/regions) fish products.
Sodium nitrite is likewise made use of in the following areas: manufacturing of diazonium substance dyes, nitroso substances and other natural compounds; dyeing and whitening of coarse fabrics; photography; as an anti-corrosion representative in labs; as an additive in steel layers; Manufacturing of rubber. Its 10% aqueous solution is additionally made use of for electroplating. Salt nitrite is likewise made use of in vasodilators, bronchodilators, and also cyanide cleansing in humans or pets.
Sodium Nitrite Uses
Nitrite is part of the average person’s daily diet and is found in many vegetables. In 34 kinds of vegetables, including different kinds of cabbage, lettuce, spinach, coriander, and radish, the nitrite content was usually between 1.1 and 57 mg/kg. The process of cooking vegetables may cause the loss of nitrate, nitrous acid The loss of salt is not significant. Raw meat contains 0.4–0.5 mg/kg nitrite and 4–7 mg/kg nitrate, while cured meat contains 10–30 mg/kg nitrate.
The metabolite of nitrite in animal tissues is usually nitric oxide, an important neurotransmitter. Nitric oxide can be initially produced from arginine by nitric oxide synthase or from nitrate and nitrite absorbed by digestion. Early research on the negative effects of nitrite on the human body led people to recognize the important role of nitric oxide in human metabolism and to know that the human body itself produces nitric oxide endogenously.
As a food additive, sodium nitrite can not only dye and preserve fish and meat food, the principle is: nitrite decomposes under acidic conditions to produce nitroso (NO), which will quickly interact with myoglobin. The reaction produces stable, bright, bright red nitrosomyoglobin. Keeps meat products a consistent bright red color. Therefore, it is especially suitable for luncheon meat, ham sausages, etc., while canned braised meat, canned stewed pork, stewed elbows and other meat products use natural color, and generally do not add sodium nitrite as a color-preserving agent. The international food additive code (INS number) of sodium nitrite is 250, so some food labels indicate the use of No. 250 additive, which is the taboo name of sodium nitrite.
Sodium nitrite can also inhibit the growth of botulinum bacteria. The latter can produce botulinum toxin, which can cause food poisoning. Under the EU standard, sodium nitrite can only be mixed with edible salt in a content not higher than 0.6%, and its E code is E250. The standard for potassium nitrite is similar.
This compound can inhibit bacterial growth, and correspondingly, at relatively high levels, it is also significantly toxic to animals, including humans. The median lethal dose of sodium nitrite for rats is 180 mg/kg, and the lowest known lethal dose for humans is 71 mg/kg, which means that a person weighing 65 kg may be killed by a minimum of 4.615 g of this substance. To avoid accidental ingestion, sodium chloride mixed with sodium nitrite (used for non-dietary purposes) is often dyed a light red.
Recent studies have found that sodium nitrite has significant effects on dilating blood vessels and improving blood circulation, including application prospects for sickle cell disease, cyanide poisoning, myocardial infarction, cerebral aneurysm, and pulmonary hypertension, some of which are currently Can cause infant death. Intravenous sodium nitrite is now used in first aid for cyanide poisoning. (see cyanide #detoxification)
Sodium nitrite is used for the conversion of amines to diazonium compounds, and the N2 group has good leaving properties, and such reactions are used to replace amino groups in production applications.
In the laboratory, sodium nitrite is also used to treat excess sodium azide.
When sodium nitrite is heated to a higher temperature (above 330 °C), it can decompose to produce sodium oxide, reddish-brown nitrogen dioxide and nitric oxide.
Sodium oxide can absorb carbon dioxide to produce sodium carbonate, which may have prevented the crew of the first submarine from suffocating at high concentrations of carbon dioxide.

The Protector of Meat Food - Sodium Nitrite
Sodium nitrite is a well-known artificial additive, which is mostly utilized as a chemical and also color-preserving agent for meat items such as bacon, sauce meat, dried duck, pork, sausage, injections, and canned meat.
In the process of meat processing, including an appropriate amount of sodium nitrite can improve the look of meat items and also make them appear bright red.
It can also prevent the reproduction of specific bacteria, specifically the harmful Clostridium, reduce the speed of food spoilage, as well as avoid as well as regulate gastrointestinal disorder triggered by it.
It needs to be kept in mind that sodium nitrite is toxic to a particular extent. Excessive consumption of sodium nitrite by the human body can oxidize the nitrite in the blood that normally supplies the oxygen called for by different tissues to methemoglobin, making it lose its oxygen-carrying ability, thus creating the human body to lose its capability to carry oxygen. Hypoxia poisoning of different cells.
Consequently, in meat items, the usage as well as residues of salt nitrite have to be strictly controlled. According to GB 2760, the optimum quantity of salt nitrite made use of in meat products is 0.15 g/kg; the recurring amount of western-style pork (baked, smoked, and also cooked pork) food is ≤ 70mg/kg, et cetera of the enabled meat Type of food, deposit ≤ 30mg/kg.
Antidote Sodium Nitrite
Sodium nitrite is also an antidote, which can oxidize hemoglobin to methemoglobin, which is easily combined with cyanide ions to form non-toxic cyanide methemoglobin. . Its detoxification process is the same as that of methylene blue, its effect is stronger than that of methylene blue, and it lasts for a longer time. For the rescue of cyanide poisoning.
Cyanide has high affinity with the ferric iron (Fe3+) of mitochondrial cytochrome oxidase, which inactivates the enzyme after binding, inhibits cellular respiration, and leads to cellular lactic acidosis and hypoxia. This strain of oxidant can oxidize divalent iron (Fe2+) in hemoglobin to trivalent iron (Fe3+) to form methemoglobin.
The Fe3+ in the iron hemoglobin has a stronger binding force to cyanide (CN-) than the Fe3+ of cytochrome oxidase. Even CN- that has been bound to cytochrome oxidase can be released again and restore the activity of the enzyme. However, the cyanide methemoglobin formed after the combination of methemoglobin and CN- gradually dissociated after a few minutes, releasing CN-, and the toxicity of cyanide was reproduced again. Therefore, this product only temporarily delays the toxicity of cyanide poisoning. This product still has the effect of dilating blood vessels.
(1) If serious adverse reactions occur during injection, the drug should be discontinued immediately.
(2) In the treatment of cyanide poisoning, both this product and sodium thiosulfate can cause a drop in blood pressure, and attention should be paid to changes in blood pressure.
(3) The cyanosis of methemoglobin caused by injection of larger doses of this product can be reduced by methylene blue.
(4) This product only temporarily delays its toxicity to cyanide poisoning. Therefore, immediately after the application of this product, sodium thiosulfate should be injected through the original intravenous needle to combine with chloride and become less toxic thiocyanate to be excreted in urine.
(5) It must be used in the early stage of poisoning, and there is no detoxification effect if the poisoning time is slightly longer.
(6) When the drug is used, the dosage should not be too small, and the affected animal should be slightly bruised in order to detoxify quickly and effectively.
(7) If the dosage is too large, due to the formation of too much methemoglobin, hypoxia symptoms such as cyanosis and dyspnea may appear.
