Chelating/sequestering agents inhibit undesirable reactions in foods by complexing metal ions. The resulting structure (chelate) immobilizes the metal ion and prevents it from reacting with other components in the system. EDTA (ethylenediaminetetraacetate) forms highly stable complexes with metal ions and is a cost-effective solution due to its effectiveness at remarkably low concentrations. 

Dow produces two food-grade products that help stop those pesky metal ions from degrading the value of your food products. Refer to our application table to see which grade of Dow VERSENE™ is appropriate for your food product.

Although citric acid, phosphates, and lactates are sometimes promoted as metal ion control agents in food applications, these graphs show that these materials are nowhere near as strong as EDTA in the typical food pH range and are particularly ineffective for copper and iron—the metals which can cause most degradation problems. The data shows why EDTA is clearly the only effective solution to metals problems.
