Food Grade Calcium Carbonate (CaCO₃, CAS 471-34-1) is one of the most widely used safe inorganic food additives globally, manufactured in standardized export-grade superfine powder specifications. Selected high-purity limestone raw material goes through multi-stage crushing, ultra-fine grinding, impurity removal and surface treatment procedures, finally forming uniform white superfine powder with adjustable particle size from 325 mesh up to 1000 mesh. The finished product achieves CaCO₃ purity above 99.0%, whiteness no less than 95%, moisture content controlled below 0.2%, and lead heavy metal limited to maximum 2 ppm, passing rigorous food safety inspection thresholds of major importing countries, no harmful residual risk for edible application.

This calcium carbonate integrates three irreplaceable functional values in food production. First, it acts as economical and efficient calcium fortifier: supplementing essential dietary calcium in flour, infant milk powder, solid beverage and dietary health food, improving nutritional value and meeting daily calcium intake demand of human body. Second, it works as premium anti-caking agent: adding into powdered food raw materials to absorb surface moisture, enhance powder fluidity, effectively avoid lump formation during transportation and shelf storage, extend product shelf life. Third, it serves as moderate functional filler for baking additives, stabilizing formula structure, regulating product bulk density and reasonably controlling comprehensive production cost without influencing original flavor and quality of finished food.

Our production line implements closed automatic production and full batch testing system, ensuring consistent mesh size, whiteness and impurity index without quality fluctuation. Different mesh options meet diversified processing demands: coarse mesh for flour modification, medium mesh for milk powder anti-caking, ultra-fine mesh for high-end health food formulation. With sufficient inventory and stable export logistics system, we provide long-term bulk order service and customized packaging solutions for global food manufacturers, grain processing plants and food additive enterprises, supplying high-quality, compliant food-grade calcium carbonate raw materials with competitive price advantages.
