Food-grade calcium carbonate (CaCO₃) is a high-purity mineral widely used in food, healthcare, and pharmaceutical applications. Its safety and quality depend strongly on the raw material source 👇

🪨 High-Purity Calcite – The best source for food-grade CaCO₃; over 99% purity, low impurities, and excellent whiteness.

🌾 Chalk (Natural Calcium Carbonate) – Soft and easy to grind, used in food additives and tablets.

🐚 Shell / Coral Calcium – Natural organic CaCO₃ with trace minerals (Mg, Zn), ideal for calcium supplements.

✅ Main Quality Requirements:

High Purity (CaCO₃ ≥ 98–99%) – Free from heavy metals like Pb, As, Hg

High Whiteness (≥ 95%) – Ensures clean and pure appearance

Fine & Uniform Particle Size (200–800 mesh) – Improves dispersion and texture

Chemically Safe – Non-toxic, non-radioactive, compliant with FDA / GB / E code standards

Odorless & Stable – Maintains food flavor and consistency

🍞 Applications: Nutritional supplements, bakery products, milk powder, toothpaste, and pharmaceutical tablets.
