PRODUCT DESCRIPTION

Sodium carboxymethyl cellulose (CMC-Na) is an organic substance with the chemical formula [C6H7O2(OH)2OCH2COONa]n. It is a carboxymethyl derivative of cellulose and the main ionic cellulose gum. Sodium carboxymethyl cellulose is usually an anionic polymer compound obtained by reacting natural cellulose with caustic soda and monochloroacetic acid, with a molecular weight ranging from several thousand to one million. CMC-Na is a white fibrous or granular powder, odorless, tasteless, hygroscopic, and easy to disperse in water to form a transparent colloidal solution.

PRODUCT USAGE

Water retention effect

Sodium carboxymethyl cellulose has a hydrating effect. In meat products, bread, steamed buns and other foods, it can improve the texture and make water less volatile, which can increase product yield and improve taste. 

Gelation effect

Thixotropic sodium carboxymethyl cellulose means that the macromolecular chains have a certain number of interactions and tend to form a three-dimensional structure. Thixotropic carboxymethyl cellulose plays an important role in gel systems and can be used to make jelly and jam. 

Film-forming property

Sodium carboxymethyl cellulose can form a film on the surface of food, which can provide some protection for fruits and vegetables. Due to the presence of the film, a low-oxygen, high-carbon dioxide gas environment is formed between the film and the fruits and vegetables, thereby reducing the gas exchange rate and material exchange rate, which is used to extend the shelf life of fruits and vegetables.

Acidic beverages

Casein will aggregate and become unstable under acidic conditions, so polysaccharides are generally added to protect casein, stabilize the system and ensure a good taste.
