Product Description

Product Description

Carboxymethyl Cellulos (CMC-Na) is an organic compound with the chemical formula [C6H7O2(OH)2OCH2COONa]n, a carboxymethylated derivative of cellulose, which is the predominant ionic cellulose gum. Sodium carboxymethyl cellulose is usually an anionic polymer compound made by the reaction of natural cellulose and caustic soda and monochloroacetic acid, with molecular weight from several thousands to millions.CMC-Na is a white fibrous or granular powder, odorless, tasteless, hygroscopic, easily dispersed in water to form a transparent colloidal solution.

3.Why use sodium carboxymethyl cellulose?

3.1 The edible sodium carboxymethyl cellulose can play a role in emulsifying and stabilizing beverages containing fat and protein, which are generally characterized by different degrees of fat and a certain amount of protein, and are easy to separate and float when stored, forming unattractive "collars" and affecting the appearance of products.

3.2 Sodium carboxymethyl cellulose has a hydration effect, in meat products, bread, buns and other food products, can play a role in tissue improvement, and can make the water is not easy to volatilize, can improve product yield, increase taste.

3.3 Thixotropic sodium carboxymethyl cellulose refers to a certain number of interactions of macromolecular chains that tend to form a three-dimensional structure. After the formation of three-dimensional structure, the apparent viscosity of the solution rises; after breaking the three-dimensional structure, the apparent viscosity decreases. The thixotropic phenomenon is that the change of apparent viscosity depends on time. Thixotropic carboxymethyl cellulose has an important role for the gel system, which can be used to make jelly and jam.

3.4 Sodium carboxymethyl cellulose can form a film on the surface of food, which can play a certain protective effect on fruits and vegetables. Due to the existence of the film, a gas environment with low oxygen and high carbon dioxide is formed between the film and fruits and vegetables, which reduces the rate of gas exchange, the rate of material exchange, and is used to extend the shelf life of fruits and vegetables.

4. The role of sodium carboxymethyl cellulose in food:

4.1. Thickening and emulsification stabilizing effect:

Protein is easy to coagulate and separate, especially for products with low pH value, protein is bound to coagulate, and sodium carboxymethyl cellulose can effectively solve these problems, it dissolves in water as transparent and stable colloid, which can stabilize protein, and at the same time reduce the surface tension between fat and water, so that fat can be fully emulsified.

4.2. Water retention effect:

Sodium carboxymethyl cellulose has the role of hydration, in meat products, bread, buns and other food products, can play a role in tissue improvement, and can make the water is not easy to volatilize, can improve product yield, increase the taste.

4.3. Film-forming property:

Sodium carboxymethyl cellulose can form a film on the surface of food, can play a certain protective effect on fruits and vegetables, due to the existence of the membrane, so that the membrane and fruits and vegetables between the formation of a low oxygen, high carbon dioxide gas environment, thereby reducing the rate of gas exchange, material exchange rate, used to extend the shelf life of fruits and vegetables

Yogurt, ice cream, liquid beverages, bread, milk, etc. but not including baby products.
