Description

Starch, Phosphate is a modified starch derivative where phosphate groups are introduced to the starch polymer, significantly altering its functional properties. This chemical modification enhances its stability, thickening power, and clarity, making it a superior functional ingredient for demanding industrial applications. It is essential for manufacturers in the food, pharmaceutical, paper, and textile industries seeking consistent performance and process efficiency.

Application

• Food Industry: Used as a thickener, stabilizer, and texturizer in sauces, gravies, soups, and dairy products, providing improved freeze-thaw stability and resistance to high-temperature processing.
• Pharmaceuticals: Serves as a binder and disintegrant in tablet formulations, and as a viscosity modifier in topical creams and lotions.
• Paper Manufacturing: Acts as a wet-end additive and surface sizing agent to improve paper strength, printability, and surface smoothness.
• Textile Industry: Employed in warp sizing to strengthen yarns and reduce breakage during weaving.
• Adhesives & Glues: Functions as a key component in water-based adhesives, offering enhanced viscosity and bonding properties.
• Biodegradable Plastics: Used in the production of starch-based bioplastics as a renewable and compostable polymer component.
