Quality Control

Our Sodium Hydrogen Dipropionate is manufactured under a strict quality management system. Production adheres to relevant food-grade and industrial standards, including potential compliance with FCC and EU regulations (E281). Every batch is subjected to rigorous analytical testing to ensure identity, purity, and performance. A Certificate of Analysis (COA) detailing specific results is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent caking and degradation from atmospheric moisture.
