Product Introduction:

Sodium citrate, also known as trisodium citrate, is a versatile compound derived from citric acid. It is a white crystalline solid that is highly soluble in water and is commonly used as a food additive, pH buffering agent, and in various industrial and medical applications.


In the food industry, sodium citrate is used as an acidity regulator, stabilizer, and emulsifying agent. It is often found in products like soft drinks, candies, and processed fruits, where it helps maintain the desired pH level and prevents spoilage. It also enhances the flavor and texture of certain foods.


In the medical field, sodium citrate is used as an anticoagulant in blood transfusions and as a component in some medications. It is also used in the treatment of certain types of metabolic disorders.


In the laboratory, sodium citrate serves as a buffering agent in various biochemical tests and as a component in bacterial culture media. Its ability to chelate metal ions makes it useful in analytical chemistry and in the preparation of pharmaceuticals.


Regarding safety, sodium citrate is generally recognized as safe (GRAS) for use in food products. However, like all substances, it should be handled with care, especially in concentrated forms, to prevent irritation to the skin and eyes.


For storage, sodium citrate should be kept in a cool, dry place to prevent deliquescence. It is important to store it away from moisture and in a well-sealed container to maintain its quality and effectiveness for various applications.
