Carboxymethyl cellulose is replaced by product group. According to their molecular weight or degree of substitution, can be completely dissolved or insoluble polymers, which can be as weak acid cation exchanger for separation of neutral or basic proteins. Carboxymethyl cellulose can form high viscosity colloid solution, there is adhesion, thickening, mobility, emulsifying, shaped, water, protective colloid, film forming, acid, salt, and other features for suspension, and no physiological harm, and therefore food, medicine, daily chemical, petroleum, paper, textiles, construction and other fields has been widely used in production. Carboxymethyl cellulose as a food additives.
Sodium carboxymethyl cellulose (CMC) an anionic cellulose ether, white or slightly yellow flocculent fiber powder or white powder, odorless, tasteless, non-toxic; soluble in cold water or hot water to form a certain stick degree transparent solution. Sodium carboxymethyl cellulose (CMC) is the production of cellulose ethers in the largest, most widely used and most convenient to use the product, commonly known as "industrial monosodium glutamate."
Replacement of the food industry with high degree of CMC for ice cream, canned food, fast cooking of the thickener, beer foam stabilizer. Widely used in dyeing, pesticide processing, pharmaceutical, paper, paint, ceramics, oil and food industry as sizing agent, thickener, emulsifier, emulsion stabilizer, binder, film-forming agent.
CMC is usually made from natural cellulose with caustic alkali and an acid chloride obtained after a reaction of anionic polymers, molecular weight 6400 (± 1 000). Main by-product is sodium chloride and ethanol. CMC is a natural cellulose modification. The present United Nations Organization (FAO) and the World Health Organization (WHO) has officially called it "modified cellulose."
Other food additives: agar agar powder Carrageenan Erythritol
