Direct product answer
What is food grade Magnesium Carbonate?
Food grade magnesium carbonate is a light or heavy white magnesium carbonate material. The supplied sheet describes a basic hydrated composition and 40.0–43.5% MgO, while Codex identifies magnesium carbonate as INS 504(i).
Commercial suitability depends on the exact grade, source, test method, application and destination-market rules. The current signed specification and batch COA govern a transaction.
Application screening
Common food grade Magnesium Carbonate applications
These are formulation areas, not universal approvals. Confirm legal use, dosage and technical performance for the finished product.
Flour systems
The supplied sheet identifies flour-improver use; confirm destination-market authorization and performance.
Mineral formulations
Match magnesium contribution, purity and bioavailability requirements to the finished product.
Dry blends
Specify light or heavy bulk density, particle behavior and moisture controls.
