Thickener CMC Powder For Ice Cream

Carboxymethyl cellulose sodium (CMC-Na) is an organic compound with the chemical formula [C6H7O2(OH)2OCH2COONa]n. It is a carboxymethyl derivative of cellulose and is the most prominent ionic cellulose gum. CMC-Na is usually obtained by reacting natural cellulose with caustic alkali and monochloroacetic acid. It is a negatively charged polymer compound with a molecular weight ranging from several thousand to millions. CMC-Na is a white fibrous or granular powder, odorless and tasteless, with hygroscopic properties. It is easily dispersed in water to form a transparent colloidal solution.

Carboxymethyl Cellulose (CMC) is a water-soluble cellulose ether obtained by chemical modification of natural cellulose. Due to the poor water solubility of the acidic structure of carboxymethyl cellulose, in order to facilitate its application, its products are generally made into sodium salts, with the molecular formula [C6H7O2(OH)2OCH2COONa]n.

Products Application

It is widely used in petroleum industry for well-drilling mud treatment agents, synthetic detergents, organic auxiliary detergents, textile printing and dyeing sizing agents, water-soluble gelled thickening agents for daily chemical products, pharmaceutical industry for thickening and emulsifying agents, food industry for thickening agents, ceramic industry for adhesives, industrial pastes, paper industry for sizing agents, etc. [4] It is also used as a flocculant in water treatment, mainly for wastewater sludge treatment, which can increase the solid content of the filter cake.
Sodium carboxymethyl cellulose is also a type of thickening agent. Due to its own excellent functional properties, it has been widely applied in the food industry, and to a certain extent, it has promoted the rapid and healthy development of the food industry. For example, due to its certain thickening and emulsifying effects, it can be used to stabilize yogurt beverages and increase the viscosity of yogurt systems; due to its certain hydrophilicity and rehydration properties, it can be used to improve the eating quality of bread and steamed buns and extend the shelf life and enhance the taste of food products; due to its certain gelation effect, it is conducive to the better formation of gels in food, and therefore can be used to manufacture jelly and jam; it can also be used as a edible coating material and can be compounded with other thickening agents for application on the surface of some foods, which can maximize food preservation and since it is an edible material, it will not have adverse effects on human health. Therefore, edible-grade CMC-Na, as an ideal food additive, is widely used in food production in the food industry.
