Sodium nitrite (colloquial, correctly - sodium nitrate or sodium nitrite) is used in industry as a food additive (as a preservative). It has a carcinogenic effect (according to some representatives of medicine, it can provoke cancer). Sodium nitrite in sausage and some other (mostly meat) products is known as E-250.
Preservatives of this type have an index from E-200 to E-229. They prevent (or rather, significantly slow down) the reproduction of fungi and various kinds of bacteria. The substance is used not only in meat products, but also in winemaking - as a means of stopping the maturation of wine (disinfectant).
Sodium nitrite is a crystalline (from light yellow to white) powder. Hygroscopic, perfectly soluble in water. When exposed to oxygen (not hermetically sealed) gradually oxidizes to NaNO3 (sodium nitrate). A very strong reducing agent. Toxic.
As a result of research, it turned out: sodium nitrite,interacting with amino acids, when heated, it gives a carcinogen that can provoke the development of cancers, incl. bowel cancer and obstructive pulmonary disease.
Why, being so dangerous, is sodium nitrite present in products entering markets and stores? In industry, it is used for the following purposes:
- as an antioxidant that gives a "natural" color to meat and fish;
- to change the mode of cooking (instead of 100 ° C, processing at 72 ° C becomes sufficient - the savings are impressive);- as an antibacterial drug against Clostridium botulinum (the causative agent of botulism). By the way, the latter becomes the culprit of severe intoxication, leading to damage to the nervous system.
The absence of the additive will give the products ugly shades from greenish to brown-gray - colors that are clearly not appetizing. From such a “beauty”, not everyone would want to make a cut, and even more so p
offer it to guests. However, even this is not the main thing. No other drug here can stop the growth of harmful bacteria. It turns out that so far it is impossible to do without the E-250. How to be? Cook by yourself! What you cook yourself will be exactly fresh and definitely without additives. And the offered factory delicacies can be pampered only occasionally and in modest amounts. In this case, you don't have to worry about sodium nitrite being harmful to your he alth.
Sodium nitrite (GOST 19906-74, m OSCh 4-7-3)added to concrete and structures as an inhibitor of AK (atmospheric corrosion); used in organic synthesis; in demand in the pulp and paper, metallurgical, medical, chemical industries.
NaNO2 is present in diazo dyes, used in dyeing natural fabrics (including bleached ones), in the production of rubber, in phosphating (in metalworking), and for removing tin. Photographers who use antioxidants when developing pictures are very familiar with it. With a reasonable approach, sodium nitrite becomes an excellent drug that relieves intestinal spasms, dilates the bronchi (vasodilator, bronchodilator), acts as a laxative and at the same time is an antidote for cyanide poisoning.
