METAL ION ISSUES IN FOOD PRODUCTS?

    Metal ions are a naturally occurring problem to food products that use water and water-soluble ingredients. These metal ions can degrade your product stability; that can lower shelf-life, degrade color retention, and cause rancidity.

DOW VERSENE™ IS THE ANSWER

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.

ADVANTAGES OF DOW VERSENE™

    Strong Compatibility
     

    VERSENE™ works well across a wide range of temperatures, light and pH level

    Exceptional Regulatory Approval
     

    VERSENE™ CA and NA are cleared by U.S. Food and Drug Administration for use in direct food and beverage applications

    Sustained Quality
     

    Dow provides unsurpassed quality and consistency 

    Colorless, Odorless, Tasteless
     

    VERSENE™ is a white powder readily dissolvable in water and causes no change to odor, taste or color
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.
