Sodium Carboxymethyl Cellulose (CMC) has function of thickening, emulsifying, suspension, water retention, tenacity strengthening, puffing and preservation in food. In food, it can improve taste, promote product level and quality and prolong storage life.
Functions of CMC in food
Thickening property: get viscosity under low concentration
Water-retaining property: reduce syneresis of food and prolong shelf life
Dispersing stability: keep food quality
Filming property: develop a layer of film on fry food
Chemical stability: stable to chemical drugs, heat and light
Properties of food CMC

Carboxy methyl 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 is synthesized by the alkali-catalyzed reaction of cellulose with chloroacetic acid. The polar (organic acid) carboxyl groups render the cellulose soluble and chemically reactive. The functional properties of CMC depend on the degree of substitution of the cellulose structure (i.e., how many of the hydroxyl groups have taken part in the substitution reaction), as well as the chain length of the cellulose backbone structure and the degree of clustering of the carboxymethyl substituents.
Insoluble microgranular carboxymethyl cellulose is used as a cation-exchange resin in ion-exchange chromatography for purification of Proteins.Presumably the level of derivatization is much lower so that the solubility properties of microgranular cellulose are retained while adding sufficient negative charged carboxylate groups to bind positively charged proteins.
CMC is also used in ice packs to form a eutectic mixture resulting in a lower freezing point and therefore more cooling capacity than ice.
Aqueous solutions CMC have also been used to disperse carbon nanotubes. It is thought that the long CMC molecules wrap around the nanotubes, allowing them to be dispersed in water.
