Sodium citrate is a salt derived from citric acid, commonly used in the food industry as a preservative, flavor enhancer, and emulsifier. It plays a vital role in balancing acidity, stabilizing certain ingredients, and preventing the formation of crystals in processed foods. Found in beverages, cheeses, and even in medical products, sodium citrate helps maintain a smooth texture and extend shelf life, making it a key ingredient in both the culinary and pharmaceutical industries. Its mild, tangy taste also contributes to the flavor profile of various products.
