KELTROL 521 is a food-grade xanthan gum suitable for use in food preparations and personal care applications. KELTROL 521 is a free-flowing powder, with low dusting characteristics, designed to hydrate more effectively than conventional food-grade xanthan products under typical plant mixing conditions. It provides excellent suspension for insoluble solids and oil droplets in food applications. KELTROL 521 exhibits low viscosity while processing and fully recovers viscosity after shearing, reducing dust exposure and improving general housekeeping. It is compatible with and stable in solutions containing high salt concentrations and soluble and stable in both acid and alkaline conditions. KELTROL 521 exhibits synergistic increase in viscosity when used with other gums, providing freeze-thaw stability and stability in food products.
