Product Description:
Meta-phosphoric acid is widely used in the food industry as a sequestrant and stabilizer, particularly in dairy products and processed meats. It helps maintain texture and prevent spoilage by binding metal ions that can catalyze oxidation. In the pharmaceutical sector, it serves as an excipient in tablet formulations to control the release of active ingredients. Additionally, it is employed in water treatment processes to inhibit scale formation and corrosion in pipelines. Its ability to form complexes with metal ions also makes it useful in analytical chemistry for sample preparation and analysis.
