Quality Control

Our 1-o-α-D-Glucopyranosyl-D-Mannitol is manufactured under a strict quality management system. Each batch is tested to ensure it meets high-purity standards suitable for pharmaceutical and food-grade applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee traceability and compliance.

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 nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product stability and flow properties.
