Description and Uses
Carboxymethylcellulose(CMC) is a gum that is water-soluble cellulose ether manufactured by reacting sodium monochloroacetate with alkali cellulose to form sodium . It dissolves in hot or cold water and is fairly stable over a pH range of 5.0–10.0, but acidification below pH 5.0 will reduce the viscosity and stability except in a special acid-stable type of CMC. A variety of types are available which differ in viscosity and degree of substitution (the number of sodium groups per unit). It functions as a thickener, stabilizer, binder, film former, and suspending agent. It is used in a variety of foods to include dressings, ice cream, baked goods, puddings, and sauces. The usage range is from 0.05 to 0.5%. Also termed cellulose gum.
