It is a white powder of synthetic origin.

It is used as a preservative and antioxidant in food production.   Slows down the development of pathogenic bacteria and inhibits oxidation.

The use of this additive is allowed in Russia and the CIS countries and the European Union.

Characteristic

E223 is produced by reacting sulfur dioxide with wet sodium carbonate.

The resulting substance is highly soluble in water, almost insoluble in alcohol, does not dissolve in oil substances at all. When burned, toxic gas emits sulfur dioxide.

Sodium pyrosulfite is used in many areas of production. In industry, it is used to prevent spoilage of products and in pharmaceuticals, as a filler for tablets, as part of disinfectants and as painkillers.

Effect on the body

Is food supplement E 223 dangerous or not? E223 practically does not harm the body, since sodium pyrosulfite is completely excreted by the liver.   However, large amounts of E223 can cause severe allergies and even Quincke's edema.

E222 powder

E222 - sodium hydrosulfite.

Available in the form of powder from small crystals or granules of a yellowish color.

It acts as a preservative, stabilizes the color, has the functions of an antioxidant and whitening.

The use of sodium hydrosulfite is prohibited in all countries of the world, except Russia and Ukraine.

Component Overview

E 222 is highly soluble in water, slightly soluble in ethanol and insoluble in oily substances.   Flammable. Upon contact with water in an oxygen-saturated environment, it releases sulfur.

The release process is accompanied by a large heat release, which can cause a fire. Sodium hydrosulfite is used in food, textile, chemical and light industries.

Human health effects

E222 is a strong poison.   In large doses, it can cause allergies. It provokes diseases of the gastrointestinal tract. Destroys vitamin B1.

Inhalation of formaldehyde vapor causes leukemia and diseases of the nasopharynx.

IMPORTANT!   Avoid food with this label!

E251

Allows you to restore the color of meat after its processing.

Its preservative properties are much weaker than that of other additives in this group. Permitted in Russia, Ukraine, EU countries and the USA.

Specific features

Sodium nitrate is a white powder, odorless. The powder tastes like ordinary table salt. Easily soluble in water.

It is used in the food industry, mainly in the manufacture of meat products.   It is an explosive substance.

Effect on the body

Sodium nitrate has a negative effect on the body as a whole.

It can cause dysbiosis, allergic reactions and provoke cholecystitis.

It has carcinogenic properties, can contribute to the formation of cancer.

High doses of the substance cause severe abdominal pain, cramps, dizziness, and fainting.

Where do they meet?

Already so firmly entered into our lives that to avoid their use completely is no longer possible. Yes, and do not be afraid of any inscription with the name of the food supplement. They are used in almost all food products.

Not all of them are harmful. You just need to learn how to choose products with the lowest content of harmful additives.

In the food industry, various preservatives are abundantly added to increase food safety. One of them is E251, which is added during the preparation of meat products, in the manufacture of cheeses, fish sprats, smoked fish. It serves the purpose of preserving goods, but contributes to the synthesis of nitrosamines in the human body, and this leads to cancer.

What is sodium nitrate?

Sodium nitrate is a chemical food supplement to increase its shelf life; it is responsible for the color quality of meat products. The substance is a sodium salt of nitrous acid from crystals that have a colorless color and is a powder without aroma; it tastes like salt. The Latin name of the substance is Sodium nitrate, the chemical formula is NaNO3 (molar mass 84.993 g / mol). To obtain it, sodium hydroxide with nitric acid or ammonium nitrate is used. A similar reaction occurs in the formula for a mixture of edible salt with silver nitrate.

The use of sodium nitrate

Options for the use of sodium nitrate:

1. Sodium nitrate gives sausage products a pleasant pink hue, prevents bacteria from multiplying, which has a positive effect on the shelf life of food. Without this substance, all sausages and sausages would be the color of boiled meat, that is, unappetizing grayish.
2. Similarly, it is used to preserve fish, so it is added to smoked and canned fishery products.
3. Production uses nitrites so that in large frosts concrete does not become ice.
4. When developing a photo, sodium nitrate (another name) acts as a reagent.
5. When fabrics are created, Sodium nitrate serves for their high-quality coloring: directly or using stencils.
6. A few more areas of use of the NaNO3 formula are the processing of metal products, the manufacture of pyrotechnics and glass, and the creation of rubber.

Sodium nitrate in medicine

It was not without sodium nitrate in medicine, because it is already initially synthesized by the human body in small volumes. Plus, the protective effect of the drug in the fight against microbes is important here. It is taken for the production of vasodilators, it helps against constipation, helps to expand the bronchi, and saves if a person is poisoned with cyanide. Its research is being carried out for the treatment of heart diseases, anemia, brain aneurysm.

Sodium nitrate supplement

Preservative E251, or Chilean nitrate, is added to meat products to form a bright pink color. He also is in cheese. Here, the additive prevents the development of certain types of bacteria. To prevent the product from expanding, cracks do not appear, E251 in cheese is a must. With a very low concentration (0.01-0.02%), it is added to milk, it is no longer needed, otherwise it will change the color of the product.

E-251 Sodium nitrate   - food preservative.

Sodium nitrate   used as a preservative, color fixative. Externally E-251   - it is transparent, colorless crystals or white powder, hygroscopic, does not have a pronounced aroma. It is well soluble in water, difficult in alcohols. Sodium nitrate   also called sodium or sodium nitrate. The chemical compound is obtained as a result of exposure to sodium. Also, food preservative E-251   formed as a result of the interaction of salt and silver nitrate. Sodium nitrate it tastes like ordinary table salt. Nitrates without impurities, the human body can tolerate in large quantities: 60% of nitrates is excreted in the urine, about 5% enter the saliva. Only nitrites or toxic and carcinogenic products formed from them are harmful to health. The amount of nitrates used as food additives is insignificant in comparison with the amount of nitrates that enter the body along with cultivated plants (improperly fertilized) and drinking water. In the small intestine and in the slightly acidic environment of the stomach of infants (but not in the strongly acidic stomach of adults), nitrates can partially recover to nitrites, which explains the greater sensitivity of infants to nitrates.

Despite the fact that the preservative E-251   it has a negative effect on the human body as a whole, the food supplement is still being used in the production process of the food group of goods. Nowadays, no type of sausage products can do without the content of sodium nitrate in the chemical composition sodium nitrate   - 5 mg / kg of body weight per day, it is not recommended to use in baby food. In Russia, it is allowed as a preservative and color fixer (colorant) in sausages and meat products (salted, boiled, smoked, canned meat in an amount of up to 250 mg / kg) individually or in combination with potassium nitrate in terms of sodium nitrate   ; hard, semi-hard, soft cheeses; milk-based cheese analogues, goose liver products in an amount up to 50 mg / kg individually or in combination with potassium nitrate in terms of sodium nitrate; in herring, salted sprats and in marinade in an amount up to 200 mg / kg. Food preservative E-251 Sodium nitrate helps sausages and meat products to acquire their characteristic "meat color". The nitrates themselves in the concentrations used in the manufacture of food products are ineffective against microbes and are not harmful to humans and animals. Their preservative effect is limited to the bactericidal of nitrites formed as a result and a decrease in water activity. These chemical reactions occur in foods only under the influence of bacteria. To activate microorganisms, salting is often added with saltpeter (a nutrient for bacteria). Nitrites exhibit antimicrobial activity in meat products, and also contribute to the appearance of a characteristic color and specific aroma. They can be used dry or as a solution. With dry salting, the meat is rubbed with a mixture of saltpeter, salt and sugar, with wet - the meat is placed in a brine consisting of the same components. In meat products sodium nitrate   has the same effect as the nitrite curing mixture, although the effective amount of nitrite is more difficult to regulate here. Therefore, in a number of countries, nitrates are prohibited in meat products, and only nitrites are allowed. In cheeses, nitrate or the nitrite formed from it inhibits certain types of bacteria of the genera Clostridium and Coli, thus preventing cracking and rupture of hard cheese circles. Sodium nitrate   or potassium is added to milk at a concentration of 0.01-0.02%. Higher concentrations are undesirable, as they can cause a discoloration of the cheese.

Other applications: as a fertilizer, an oxidizing agent in glass production, as a component of liquid salt refrigerants (saltpeter mixture), a component of quenching baths in the metalworking industry and in rocket fuel.

There is a list of contraindications for sodium nitrate. Harmful food preservative E-251 Sodium nitrate   can be especially significant if a person suffers from ^

• hypertension
• liver disease;
• intestines;
• also a vegetovascular system. In addition, a food preservative E-251 Sodium nitrate   can provoke dysbiosis, cholecystitis, as well as severe allergic reactions. It is worth noting that when a food preservative is ingested E-251 Sodium nitrate   into the human body, the chemical properties and characteristics of nitrate change. Biologically active substance sodium nitrate, which is contained in the chemical composition of the preservative, is converted to a carcinogen. Carcinogens, in turn, are considered dangerous compounds, as they can provoke the onset and development of malignant cancers. With an overdose of sodium nitrate, the following symptoms appear:
• sharp abdominal pain;
• cramps
• impaired coordination of movements;
• fainting
• dizziness and general weakness.

Food preservative E251 Sodium nitrate is also called sodium nitrate or sodium nitrate. A chemical compound is obtained by exposure to nitric acid. In addition, the food preservative E251 Sodium nitrate is formed as a result of the interaction of food salt and silver nitrate. The biologically active substance sodium nitrate, which is part of the food preservative E251, is obtained in a powdery state of aggregation. Moreover, sodium nitrate does not have a pronounced aroma.

On the palate, the food preservative E251 Sodium nitrate is similar to ordinary table salt. Most often, the food preservative E251 Sodium nitrate is used for the manufacture of canned meat products or frozen processed foods. Sodium nitrate can restore the color of processed meat. We can say that it is the food preservative E251 Sodium nitrate that helps sausages and meat products to acquire their characteristic "meat color".

Interestingly, the antimicrobial properties of the food preservative E251 Sodium nitrate are significantly inferior to other food additives, which are classified as preservative chemicals. Typically, the food preservative E251 Sodium nitrate is used as a color stabilizer or dye. However, the E251 preservative can help prevent the onset and development of anaerobic microorganisms. Perhaps the useful properties of the preservative end there.

Harm food preservative E251 Sodium nitrate

Despite the fact that the preservative E251 has a negative effect on the human body as a whole, the nutritional supplement is still continued to be used in the production process of the food group of goods. Nowadays, no type of sausage products can do without the content of sodium nitrate in the chemical composition. As a result of scientific research and laboratory experiments, the harm of the food preservative E251 Sodium nitrate to the normal functioning of the human body was identified.
