Nitrites, particularly sodium nitrite, are another critical group of antimicrobial preservatives, especially in cured meats. They not only prevent the growth of Clostridium botulinum, the bacterium responsible for botulism, but also contribute to the distinctive flavor and color of cured products. However, their use has come under scrutiny due to concerns about the formation of nitrosamines, potentially harmful compounds that can occur during cooking. As a result, regulatory agencies have established strict limits on nitrite levels in food, ensuring that their benefits can be enjoyed while minimizing potential health risks.
