Easy Soluble in Water 9004-32-4 Food Grade Sodium Carboxymethyl Cellulose (CMC)

Product details

MF: C8H16NaO8
CAS: 9085-26-1

1.Sodium carboxymethylcellulose (CMC) is a carboxymethylated derivative of cellulose, also known as cellulose glue. It belongs to anionic cellulose chemicalbook vitamin ether and is the most important ionic cellulose glue. It is usually an anionic polymer compound prepared by the reaction of natural cellulose with caustic soda and monochloroacetic acid. The molecular weight of the compound ranges from thousands to millions.

2.CMC is white or milky fibrous powder or particles, with a density of 0.5-0.7 g / cubic centimeter, almost odorless, tasteless, and hygroscopic. It is easy to disperse in water into a transparent colloidal solution and insoluble in organic solvents such as ethanol. The pH of 1% aqueous solution is 6.5 ~ 8.5. When ph>10 or <5, the viscosity of the slurry decreases significantly, and the performance is the best when ph=7. For thermal stability, the viscosity rises rapidly below 20chemical book ℃, and changes slowly at 45 ℃. Long time heating above 80 ℃ can denature its colloid and significantly reduce its viscosity and properties. Soluble in water, transparent solution; It is very stable in alkaline solution, and it is easy to hydrolyze in case of acid. Precipitation will occur when the pH value is 2-3, and precipitation will also occur in case of multivalent metal salt. Solid CMC is relatively stable to light and room temperature, and can be stored for a long time in a dry environment.

Application

1.Sodium carboxymethyl cellulose can be used as thickener, stabilizer and emulsifier. The specific application fields are as follows: 1 Application of CMC in food edible CMC has the characteristics of thickening, emulsifying, shaping, water retention, stability and so on.

2.Adding CMC to food can reduce the production cost of food, improve the grade of food, improve the taste of food, and extend the quality guarantee period of food. It is an ideal food additive in the food industry. It can be widely used in all kinds of solid and liquid beverages, cans, candies, cakes, meat products, biscuits, instant noodles, roll noodles, quick boiled food, quick-frozen flavor snacks, soymilk, yogurt, peanut milk, fruit tea Fruit juice and other food production.

3.CMC has different uses and dosage in different foods.
