Is Potassium Nitrate Dairy Free?

Potassium nitrate is a chemical compound with the formula KNO3. It occurs naturally in mineral deposits and is commonly used in the food industry as a preservative and curing agent, particularly in processed meats like bacon and ham. It helps prevent the growth of bacteria and maintains the red color of meats by stabilizing myoglobin. While it can be derived from natural sources, potassium nitrate is sometimes synthesized using animal-derived products, which may concern some vegans.
