Natriumstärkeglukaatti

Natriumstärkeglukaatti is a chemical compound derived from starch. It is a sodium salt of a glucidic acid that is formed by the oxidation of starch. This process modifies the starch molecule, giving it new properties that are useful in various industrial applications.

The production of natriumstärkeglukaatti typically involves treating starch with oxidizing agents, such as hydrogen peroxide or sodium hypochlorite, under controlled conditions. This reaction introduces carboxyl groups onto the starch chain, which are then neutralized with a sodium source to form the sodium salt. The degree of oxidation can be varied to produce different grades of the product, each with specific characteristics.

Natriumstärkeglukaatti is a white or off-white powder that is soluble in water. Its key properties include good film-forming abilities, thickening capabilities, and emulsifying properties. It is also known for its biodegradability, making it an environmentally friendly alternative in some applications.

This compound finds use in a range of industries. In the paper industry, it acts as a surface sizing agent, improving the strength and printability of paper. In the textile industry, it can be used as a finishing agent. It is also employed as a binder, stabilizer, or thickener in food products, though its use in food is subject to regulatory approval in different regions. Additionally, it can be found in adhesives, cosmetics, and pharmaceuticals.
