Sodium benzoate is the sodium salt of benzoic acid and is naturally found in various fruits, including cranberries, prunes, and cinnamon. When used in foods and beverages, it acts as a preservative by converting to benzoic acid in acidic environments (pH below 7). The compound is particularly effective in products with a low pH, making it ideal for acidic foods such as pickles, sauces, and soft drinks.
Ethylenediamine finds extensive applications in several sectors, including pharmaceuticals, agriculture, and polymer production. In the pharmaceutical industry, it serves as a precursor for various drugs and can be used to create different chemical structures that have therapeutic effects. Ethylenediamine derivatives are often utilized in the synthesis of antihistamines, antibiotics, and other pharmaceutical agents.

Health Considerations
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.
