Carboxymethyl cellulose (CMC) or cellulose gum is a cellulose derivative with carboxymethyl groups (-CH2-COOH) bound to some of the hydroxyl groups of the glucopyranose monomers that make up the cellulose backbone. It is often used as its sodium salt, sodium carboxymethyl cellulose. It used to be marketed under the name Tylose, a registered trademark of SE Tylose. Carboxymethyl Cellulose (CMC) is white or yellowish powder that is odorless ,tasteless and non-toxic . It has high hygroscopicity and is soluble in water to form a thick liquid . It is a polyanionic electrolyte and not fermented . It has good heat-stability . resistance to salt and film-forming property . It is a strong emulsifier for fat and oil .
2. Application in food industry
Carboxymethyl Cellulose CMC Cellulose Gum has the ability to withstand boiling, freezing and even subfreezing temperatures for a short time allowing it to be a handy addition during the processing of specialty foods. It functions as a thickener, water retainer, emulsifier, stabilizer, protective colloid, suspending agent, gelling agent, and flow control agent. It is also used as film-forming and binding agent.
If sodium carboxymethyl cellulose is added into jam and cream, smearing property can be improved. Besides, sodium carboxymethyl cellulose can also be used for the preservation of fruits, vegetables and eggs. 2%-3% sodium carboxymethyl cellulose solution containing carboxybenzoate can be used in the coating and drying of fruits, vegetables and eggs in order to keep the flavor and resist mildew, with preservation effects. It has strong swelling property after absorbing water, but it is not easy to digest, so can be used for biscuits and act as diet food. It has the stabilizing property, so can be used for the foam stabilizer in beer. It also has viscosity, stability and protective colloid property, etc., can be used in ice cream to improve the water retention and tissue, but the effect can be better when used in combination with thickeners such as sodium alginate. In addition, it can also be used as such solid agents as powdered fat and spices.

The product is packed in polyethylene bag enclosed in composite paper bag . The net weight is 25 kg/bag .
Carboxymethyl Cellulose should be kept in the original bag and stored in the dry and clean place far away from the source of heat and not put together with other chemicals .
【Transportation and Storage】
The direct addition of the product to water causes the formation of lumps . Lumping results from incomplete wetting of the individual powder particles . Only the powder in contact with water dissolves and the formed gelatinous membrane prevents the remaining powder from dissolving , causing a delay in the dissolution time . The following three methods are recommended for dissolution without forming lumps . The most convenient method should be chosen according to the purpose of your application .
