Louis François Trisodium Citrate (E331) is a versatile, food-grade additive widely used in the culinary and food processing industries. This odorless, white crystalline powder serves multiple functions, including acting as an acidity regulator, emulsifier, flavor enhancer, and preservative. In dairy products, it prevents the separation of fats, ensuring smooth and creamy textures in cheeses and sauces. As a buffering agent, it helps maintain optimal pH levels in beverages, jams, and processed foods, enhancing flavor stability and extending shelf life. Additionally, Trisodium Citrate chelates metal ions, preventing oxidation and preserving the quality of fats and oils.
