Sodium nitrate is used in food primarily as a preservative and color fixative in cured meats and poultry. It helps prevent the growth of bacteria, particularly Clostridium botulinum which causes botulism, and helps maintain the pinkish-red color of meats, making them more appealing and marketable. Additionally, it acts as an antioxidant, slowing down the rancidity of fats that can affect the flavor and safety of the meat products. While it's regarded as safe in limited quantities, it's also important to consume such products in moderation.
