Food Additive 9004-32-4 Sodium Carboxymethyl Cellulose CMC
Sodium carboxymethylcellulose (CMC-Na) is an organic compound with the chemical formula [C6H7O2(OH)2OCH2COONa]n. It is a carboxymethylated derivative of cellulose and the most important ionic cellulose glue. Sodium carboxymethyl cellulose is an anionic polymer compound, molecular weight from thousands to millions. CMC-Na is a white fibrous or granular powder, odorless, tasteless, hygroscopic, and easily dispersed in water to form a transparent colloidal solution.

Thickening and emulsifying stabilization
The edible sodium carboxymethyl cellulose can play an emulsifying and stabilizing role in the beverage containing oil lipoprotein, and CMC-Na can be dissolved into a transparent and stable colloid in water, which can stabilize the protein, and reduce the surface tension between fat and water, so that the fat is fully emulsified. Therefore, CMC-Na is often used as a thickener in the food industry.
Water retention
Sodium carboxymethyl cellulose has a hydration effect, in meat products, bread, steamed bread and other foods, can play a role in tissue improvement, and can make water less volatile, can improve product yield, increase taste.
Gelation
Thixotropic sodium carboxymethyl cellulose refers to large molecular chains that have a certain number of interactions and tend to form three-dimensional structures. After the three-dimensional structure is formed, the apparent viscosity of the solution increases. After breaking the three-dimensional structure, the apparent viscosity decreases. Thixotropy is a time-dependent change in apparent viscosity. The thixotropic carboxymethyl cellulose plays an important role in the gel system and can be used to make jellies and jams.
Film-forming property
Sodium carboxymethyl cellulose can form a film on the surface of food, which can play a certain protective role for fruits and vegetables. Due to the existence of the film, a low oxygen and high carbon dioxide gas environment is formed between the film and fruits and vegetables, which reduces the exchange rate of gas and the exchange rate of matter, and is used to extend the shelf life of fruits and vegetables.
Sodium carboxymethyl cellulose also has some other properties, such as suspension and chemical stability, which also laid the foundation for its wide application in the food industry.
