What is Sodium Citrate?
Sodium Citrate (Na₃C₆H₅O₇), also known as Trisodium Citrate, is the sodium salt of citric acid. It is a white, crystalline powder with a slightly salty and sour taste. It is widely used as a food additive, buffering agent, emulsifier, and preservative in food and beverage applications, as well as in pharmaceutical formulations and industrial processes.
Polychem Industries supplies Sodium Citrate in food grade and pharmaceutical grade to manufacturers, food processors, beverage companies, and pharmaceutical formulators across India and internationally. It is one of the most widely consumed food additives globally and is approved by FSSAI, FDA, and international food safety authorities.
