Food‑grade magnesium carbonate is a high‑purity fine white powder, which can be sourced from magnesite ore or manufactured via synthetic routes. Though its chemical formula is MgCO₃, it commonly exists as basic hydrated forms such as Mg₅(CO₃)₄(OH)₂·4H₂O. Unlike industrial‑grade counterparts, food‑grade magnesium carbonate undergoes strict heavy‑metal and impurity control, rendering it fit for food‑contact and human ingestion.
