Sodium carboxymethylcellulose (CMC) is a carboxymethylated derivative of cellulose, also known as cellulose gum, which belongs to anionic cellulose ether and is the most important ionic cellulose gum. It is usually an anionic polymer compound prepared by reacting natural cellulose with caustic alkali and monochloroacetic acid. The molecular weight of the compound varies from several thousand to one million. CMC is white or milky white fibrous powder or granules, with a density of 0.5-0.7 g/cm3, almost odorless, tasteless, and hygroscopic. Easily dispersed in water to form a transparent colloidal solution, insoluble in organic solvents such as ethanol. The pH of 1% aqueous solution is 6.5-8.5, when the pH>10 or <5, the viscosity of the mucilage decreases significantly, and the performance is the best when the pH=7. Stable to heat, the viscosity rises rapidly below 20°C, and changes slowly at 45°C. Long-term heating above 80°C can denature the colloid and significantly reduce the viscosity and performance. It is easily soluble in water, and the solution is transparent; it is very stable in alkaline solution, but it is easily hydrolyzed when it encounters acid. When the pH value is 2-3, it will precipitate, and it will also react with multivalent metal salts. Solid CMC is relatively stable to light and room temperature, and can be stored for a long time in a dry environment.

1. The application of CMC in food Edible CMC has the characteristics of thickening, emulsification, shaping, water retention and stability. Adding CMC to food can reduce the production cost of food, improve the quality of food, improve the taste of food, and prolong the shelf life of food. It is an ideal food additive in the food industry and can be widely used in various solid and liquid beverages, cans, and candies. , cakes, meat products, biscuits, instant noodles, rolled noodles, quick-cooked food, quick-frozen flavor snack food and soy milk, yogurt, peanut milk, fruit tea, fruit juice and other food production. In different foods, CMC has different uses and dosages
2. The use of CMC in the pharmaceutical industry: it can be used in the pharmaceutical industry
