The use of ion exchange resin for organic acid purification.
Unsere stets einsatzbereiten technischen Support- und Serviceteams gehen noch einen Schritt weiter, um Ihre vertrauenswürdigste Ressource zu sein. Wir sind für Sie da.
Organic acid purification for food and beverage products encompasses lactic and citric acid purification. They serve as an additive and preservative in food and beverage applications.
The main applications of ion exchange resins in organic acid purification are chromatographic separation and demineralization. For chromatographic separation, ion exchange resins purify the filtered organic acid broth by removal of residual sugars and salts. In demineralization applications, strong acid cation resins convert mineral salts to mineral acids whereas weak base anion resins remove the mineral acids by displacing the more weakly held organic acids that are adsorbed onto the sites.
Purolite partners with customers on research and development projects to develop tailored resins for the latest applications. We also provide value to the food and
beverage industry by offering outstanding technical sales and support, global presence, a customer-centered approach, and top-tier research and development laboratories and resources.
Meeting Complex Regulatory Needs
Purolite’s organic acid purification resins must meet FDA guidelines (USA) and REACH requirements (EU). Purolite produces Halal products under the supervision of several respected Islamic councils and manufacture products in compliance with Kosher production and packaging rules.
Quality and consistency are key components and an essential part of chemicals. ISO and additional standards associated with quality management, good manufacturing practices, and ease of access to regulatory information are all well regarded and extremely relevant to the food and beverage industry. Purolite has a dedicated, global regulatory team at our manufacturing locations to support your applications and management of change initiatives.
