Carboxymethyl Cellulose is an anionic, water-soluble cellulose ether. It can greatly change the viscosity of most commonly used aqueous solutions. In food industry, sodium salt has the most practical value, so we usually use CMC to refer to Sodium Carboxymethyl Cellulose.
CMC, used as an additive in food industry, has many functions such as thickening, suspension, emulsification, stability, conformal, film-forming, bulge, antiseptic and fresh-keeping, acid resistance and health care. It can replace Gelatin, Agar, Sodium Alginate and Pectin in food production.
