Quality Control

Our Dehydroerythorbic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets the high-purity standards required for food and pharmaceutical applications. Certificates of Analysis (COA) documenting purity, identity, and impurity profiles are available for every shipment. We can supply grades compliant with FCC (Food Chemicals Codex) and other relevant industry specifications upon request.

Storage

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