Overview of Carboxymethyl Cellulose and its Uses

CMC is a cellulose derivative that contains carboxymethyl groups formed when cellulose reacts with chloroacetate in an alkali to induce replacements in the C2, C3, or C6 positions of glucose units (Gelman, 1982). As a result, CMC is more water soluble and more susceptible to cellulase hydrolysis. CMC is thus a helpful additive to both liquid and solid media for detecting cellulase activity, and its hydrolysis can then be detected using the Congo red dye, which binds to intact -d-glucans. Clearing zones around colonies growing on solid medium containing CMC and then staining them with Congo red provides a good technique for detecting CMC hydrolysis and thus -d-glucanase activity (Teather and Wood, 1982). Inoculating isolates onto membrane filters placed on the surface of CMC agar plates is a valuable modification of this approach since the filter may then be removed, revealing clear zones in the agar beneath cellulolytic colonies.

Carboxymethylcellulose. Carboxymethylcellulose (CMC) is a cellulose derivative that is anionic and water soluble. Cross-linked sodium carboxymethyl cellulose, like other modified celluloses, is thought to be low in toxicity. Because it is insoluble in water due to cross-linking, it is less likely to be absorbed than the parent chemical. Despite the fact that cellulose gum is widely regarded as a safe and appropriate food additive, it is possible that there are still unknown dangers because it is not a whole food. cellulose is a complex carbohydrate that is found in most plants' cell walls and is used to make a variety of products such as paper, textiles, medicines, and explosives, while carboxymethylcellulose is the result of cellulose's reaction with in organic chemistry.

Although cellulose is insoluble in water and most organic solvents,2 cellulose derivatives are. For example, cellulose acetate is soluble in acetone, tetrahydrofuran, and other organic solvents, whereas methylcellulose, ethyl hydroxyethyl cellulose, and sodium carboxymethyl cellulose are not. CMC is commonly used in food to absorb and hold water, limit crystal development, thicken, serve as a binder, extend shelf life, and create desirable texture or body. Its most common application is in the manufacture of dry pet foods that, when combined with warm water, generate their own gravy. Carboxymethyl cellulose sodium is used as a viscosity modifier, thickener, and emulsion stabiliser in food and cosmetics. It's also utilised in the manufacturing of water-based paints and paper.
