Lesson plan
sequestrant
A sequestrant is a food additive which improves the quality and stability of foods. A sequestrant forms chelate complexes with polyvalent metal ions, especially copper, iron and nickel. This can prevent the oxidation of the fats in the food. Sequestrants are therefore a type of preservative. The name comes from Latin and means "to withdraw from use". Common sequestrants are: * Calcium chloride (E509) * Calcium acetate (E263) * Calcium disodium ethylene diamine tetra-acetate (E385) * Glucono delta-lactone (E575) * Sodium gluconate (E576) * Potassium gluconate (E577) * Sodium tripolyphosphate (E451) * Sodium hexametaphosphate (E452i) Sodium and calcium salts of EDTA are also commonly used in many foods and beverages.
