CMC is the abbreviation of sodium carboxymethyl cellulose salt, is an important water-based cellulose ether, is a natural fiber through chemical chemical modification of a hydrophilic compound, with good thickening, stability, film formation and so on. It is widely used in food, toothpaste, lithium battery, medicine, daily chemical and other fields, and is known as "industrial MSG".

Characteristics of sodium carboxymethyl cellulose (CMC) :
1. Hydrophilic: easily soluble in hot and cold water;
2. Thickening: CMC can obtain stable viscosity at low concentration;
3. Water retention: It has hydration effect, which makes the water non-volatile in the flour products, improves the yield and enhances the taste;
4. Film formation: the aqueous solution forms a tough transparent film on the surface of the object;
5. Metabolic inertia: as a food additive, it does not participate in metabolism and provide heat, and has no physiological toxicity;
6. Stability: The emulsification performance of vegetable oil, vegetable oil, protein and aqueous solution is extremely excellent, so that it forms a stable uniform emulsion;
7. Wide range of uses: the diversification of specifications makes its application field very wide;
