Food Grade Calcium Carbonate Powder

Our Food grade calcium carbonate powder is manufactured from natural high-purity calcite and premium low-impurity limestone as raw materials, and refined through a closed-loop process including multi-stage crushing, ultra-fine grinding, magnetic separation for impurity removal, and sterile classification. As a core functional calcium-based raw material in the food processing sector, our Food grade calcium carbonate powder is produced in strict compliance with national food safety standards, with full traceability from ore mining to finished product packaging. It boasts high purity, low impurities, and heavy metal residues far below the limits set by national standards. It can be widely used as an acidity regulator, curing agent and nutrient fortifier carrier, adapting to the process requirements of various food production.

Different from ordinary industrial-grade calcium carbonate, our Food grade calcium carbonate powder has remarkable advantages in whiteness, particle size uniformity and hygiene indicators. Relying on our own mines and fully automated sterile production lines, we can stably supply products with fineness specifications ranging from 200 mesh to 1250 mesh. The products feature regular particle morphology and excellent dispersibility, mix easily without agglomeration in food systems, can effectively improve product texture while accurately supplementing calcium, and are the preferred raw material for customers in the dairy, baking, jelly and sugar industries.

● Dairy and calcium-fortified foods: Added as a calcium source to calcium tablets, calcium milk and milk beverages, with high bioavailability, no off-flavor, and no impact on the original flavor of products.

● Sugar and confectionery processing: Used for syrup decolorization and clarification, jelly curing and candy polishing, to enhance product clarity and texture stability.

● Baked goods: Regulate dough acidity, improve the fluffiness and crust color of baked products, and extend shelf life.

● Food processing aids: Used in processes such as sodium alginate extraction and soybean product coagulation, with mild reaction and no residue.

We own our own high-grade limestone mines and modern food-grade production bases, with an annual production capacity exceeding 100,000 tons. We are equipped with fully enclosed sterile production workshops and laser particle size testing equipment. The whole process from ore sorting, crushing and grinding to classification and packaging is under automated control. We can stably supply food-grade raw materials in bulk, and support customized production with different fineness and whiteness to meet the personalized needs of different food processing scenarios.

We have established a strict food-grade quality control system, and each batch of products undergoes three rounds of inspection: component monitoring starting from raw ore delivery, online detection of particle size and whiteness during production, and testing of key indicators such as heavy metals and microorganisms before finished products leave the factory. The products comply with GB 1886.214 National Food Safety Standard. Factory inspection reports can be provided with the goods, and third-party authoritative testing is also supported to ensure that every batch of Food grade calcium carbonate powder meets the standards consistently.

We provide a variety of food-grade packaging specifications: 25kg food-grade film-coated woven bags (lined with double-layer PE film, heat-sealed), 500-1000kg bulk ton bags, and small-size customized packaging is also available according to customer requirements. Products are stored in a dedicated dry and clean warehouse and transported in full seal to avoid contamination. The shelf life is 12 months under dry conditions, ensuring stable product performance within the validity period.
