Used as a preservative and antimicrobial agent in food products, particularly in processed meats and poultry, to extend shelf life by inhibiting the growth of bacteria such as Listeria. It helps maintain freshness and safety while also acting as a humectant to retain moisture. Commonly found in ready-to-eat meals, sausages, and deli meats. Also used in some cosmetic and personal care formulations for pH control and moisturizing properties.
