Nitrate

Nitrates are naturally occurring compounds found in soil, water, and plants. In food production, they are often added as sodium nitrate or potassium nitrate. These salts are manufactured through chemical processes.

Nitrates are used as preservatives in cured meats and some cheeses. They help prevent the growth of harmful bacteria like Clostridium botulinum, which causes botulism. They also contribute to the pinkish-red color and distinct flavor of cured meats.

Sodium nitrate and potassium nitrate are permitted food additives in the US. The FDA considers them safe when used as intended. Some research has explored a link between high intake of nitrates, particularly from processed meats, and potential health concerns, but the evidence is mixed and not conclusive. JECFA has evaluated nitrates and set acceptable daily intakes.
