Product Overview & Executive Summary
Food Grade Light Magnesium Carbonate Powder - Product Datasheet & Specifications
Product Name: Food Grade Light Magnesium Carbonate Powder
Synonym: MgCO3 Powder, Light Magnesite Powder, Food Grade Magnesium Carbonate
Chemical Formula: MgCO3
CAS Number: 546-93-0
EINECS Number: 208-915-9
Product Description
Food Grade Light Magnesium Carbonate Powder is manufactured from high-quality magnesium sources via precipitation, filtration, washing, drying, and fine milling processes. The resulting powder features ultra-fine, uniform particles, high magnesium carbonate content (≥95% MgCO3), and minimal impurities, making it fully compliant with food safety regulations.
The powder exhibits low moisture content (<0.5%), adjustable bulk density (0.2–0.4 g/cm³), and fine particle size (D50 5–20 μm), allowing controlled solubility, reactivity, and functional performance in food and beverage formulations. Its lightweight, free-flowing nature ensures efficient handling, precise dosing, and long-term storage stability.
Food Grade Light Magnesium Carbonate Powder is commonly used in functional foods, fortified beverages, antacids, dietary supplements, and premix blends, and also serves as a neutralizing agent or pH regulator in food applications.
