nátriumkarboximetilkeményít

nátriumkarboximetilkeményítő is the sodium salt of carboxymethyl ether of starch. It is a modified starch that is water-soluble and widely used as a thickener, stabilizer, and binder in various industries. Its production involves the chemical reaction of starch with sodium monochloroacetate in an alkaline medium. This process introduces carboxymethyl groups onto the starch molecule, rendering it soluble in water and imparting its functional properties.

The primary applications of nátriumkarboximetilkeményítő are found in the food industry, where it serves as a food additive (E466) to improve texture, prevent syneresis, and enhance the mouthfeel of products such as ice cream, sauces, baked goods, and processed meats. In the pharmaceutical sector, it acts as a disintegrant in tablets, helping them to break down efficiently in the body, and as a binder in tablet formulations. It is also utilized in the textile industry as a sizing agent to strengthen yarn and improve its weaving performance, and in the paper industry as a surface sizing agent to enhance printability and reduce ink penetration. Furthermore, its properties make it useful in detergents as an anti-redeposition agent, preventing dirt from settling back onto fabrics during washing. The specific degree of substitution of carboxymethyl groups influences its solubility and viscosity, allowing for tailored applications.
