Nitrates and Nitrites

Nitrates and nitrites are chemical compounds often used in food preservation particularly in processed meats such as sausages and bacon. They help prevent the growth of bacteria including Clostridium botulinum a dangerous microbe that can cause severe food poisoning. Nitrites react with myoglobin a protein found in muscles to give processed meats their attractive pink color. However when consumed in excess nitrites can turn into potentially harmful substances. It is therefore crucial to regulate their use to protect health while maintaining food quality.
