Disodium EDTA is a food additive. Disodium EDTA is abbreviated as disodium EDTA, and its chemical formula is C 10H 14N2Na2O8. It is a food additive. It is a white crystalline powder, odorless, tasteless and easily soluble in water. Disodium EDTA is often used as stabilizer, coagulant, antioxidant and preservative in food industry. It can form a stable complex with metal ions (such as calcium ions and magnesium ions), thus preventing metal ions from precipitating or crystallizing in food and maintaining the stability and texture of food. In addition, it can prolong the shelf life of food and prevent oxidative corruption.
