Applications

Sodium citrate is non-toxic, has pH regulation performance and good stability, so it can be used as feed additive and food additive with the largest demand. It is mainly used as seasoning agent, buffer, emulsifier, expansion agent, stabilizer and preservative.
Sodium citrate injection, like potassium salt, is used to correct the acidity of blood, body fluid and urine, as diuretics, expectorants, etc. Sodium citrate combined with other reagents can be used to purify animal liver RNA.
