Sodium nitrite granular is a white to light yellow crystalline powder, a type of inorganic salt that is commonly used as a food preservative and color fixative. Its chemical formula is NaNO2 and it is highly soluble in water.
Sodium nitrite granular is widely used in the meat industry as a curing agent to prevent bacterial growth and to give processed meats such as bacon, hot dogs and deli meats their characteristic pink color. It also imparts a slightly salty and tangy flavor to the meat.
Apart from food industry, sodium nitrite granular is used in various industrial applications such as the manufacturing of dyes, bleaching agents, and corrosion inhibitors. It is also used in the production of nitric oxide which is used in medical applications such as the treatment of pulmonary hypertension and angina.
However, excessive consumption of sodium nitrite granular can be harmful to human health. It can react with amino acids in the stomach to form nitrosamines which may increase the risk of cancer. Therefore, its use in food products is strictly regulated by food safety agencies around the world.
