Food preservatives
Sodium nitrite is most often used as a stabilizer and additive in the food industry. It is antibacterial and inhibits the growth of harmful pathogens and disease-causing bacteria. Food preservatives such as smoked fish and lunch meat use sodium nitrite. It prevents meat products from causing botulism, a serious disease caused by the bacteria botulinum in food. Currently, the US Drug and Food Administration has stipulated that the amount of sodium nitrite used in food should not exceed 200 parts per million.
Disease treatment
In addition to food processing, sodium nitrite also has certain uses in the medical field. The American Heart, Lung and Blood Association found that low concentrations of sodium nitrite can be used to treat disease. A report by the National Academy of Sciences claims that long-term low-dose sodium nitrite can restore blood circulation in the hindlimbs of rats. The study also suggests that low-level dietary sodium nitrite combined with sodium nitrate can treat cardiovascular disease by strengthening or repairing damaged blood vessels.
Pigments and Dyes
Sodium nitrite is also used as a bleach and dye. It can be used to produce basic dyes, acid dyes, direct dyes, sulfur dyes, diazo and azo dyes. Sodium nitrite dye can irritate the respiratory system, eyes, and skin, so handle with caution. Ingestion of this compound is toxic and heating with flammable materials can cause an explosion.
Other uses
Other uses of sodium nitrite include the production of herbicides, organic pesticides, printing on cast iron and steel, as a polymer inhibitor, antifreeze, lubricants, rubber processing, pulp and paper, industrial and household cleaners, and raw materials for the production of saccharin, etc.
