Food-Grade Calcium Carbonate is a purified, finely ground calcium salt used as an acidity regulator, anti-caking agent, calcium supplement and white colouring agent in food applications.We supply bulk Calcium Carbonate sourced from leading China manufacturers, available in powder form to meet global food industry demand. Our Calcium Carbonate is widely used in cereal calcium fortification, dietary calcium supplements, white food colouring, powdered foods and dairy and confectionery.
Food-Grade Calcium Carbonate (CaCO₃) is produced from high-purity limestone or precipitated synthetically (PCC).
It serves multiple functions in food: acidity regulator (antacid), calcium fortification source (40% elemental calcium), anti-caking agent, colour (white opacifier, E170), and processing aid. Widely used in flour fortification, dairy, confectionery, supplements and beverages.
