Mineral
High-Content Cost-Effective Base Material for Food Calcium Fortification
Calcium Carbonate is a classic inorganic-calcium nutritional fortifier permitted by national standards. It includes food-grade light calcium carbonate and heavy calcium carbonate, refined and purified from natural minerals. Featuring high calcium content, excellent cost-performance, strong physicochemical stability and broad processing adaptability, it is the most widely-used basic calcium-supplement source in food, health-food and dietary-supplement sectors. It possesses four core attributes: high calcium content, stable performance, multi-process adaptability and strong formula versatility.
Main Components: Calcium Carbonate, molecular formula CaCO₃, CAS No. 471-34-1
Core Specifications: Calcium content ≥39.0 %, purity ≥98.0 %; heavy metals (lead, arsenic, cadmium) comply with limits specified in GB 1886.214; loss on drying, hydrochloric-acid-insoluble substances, fluorides and other indicators meet regulatory requirements; customisable particle-size available.
Appearance: Pure-white fine powder, odourless and tasteless. Uniform loose powder with good flowability, free of caking and visible impurities, high whiteness.
Stability: Stable physicochemical properties, heat-resistant, baking-resistant and extrusion-processing-resistant, resistant to denaturation and decomposition. Shelf-life: 24 months under sealed, cool and dry storage conditions.
Solubility: Insoluble in water and ethanol; dissociates and dissolves to release calcium ions under gastric-acid acidic conditions. Exhibits excellent compatibility with cereals, powders, colloids, sugar alcohols, vitamins and minerals.
➢Regulatory: Complies with GB 1886.214-2016, listed as an approved nutritional-fortifying calcium source under GB 14880. Permitted for ordinary foods, special-diet foods and health foods with compliant labelling without application restrictions.
➢Content: Base material with industry-leading calcium content close to 40 %. Lower addition dosage for equivalent calcium-supplement effect, delivering remarkable formula-cost advantages.
➢Stability: Heat-resistant against harsh processing conditions such as baking, extrusion-puffing and high-temperature sterilisation. Low processing loss and high finished-product stability.
➢Formulation Suitability: Primarily applied in solid-state systems, compatible with cereals, baked goods, compressed tablets, solid beverages and meal-replacement powders. It is the preferred basic calcium source for powdered foods.
➢Practicality: Consistent batch-to-batch performance, high purity and few impurities. Odour-free without adverse impact on product flavour, offering far superior cost-performance compared with various organic calcium sources.
Calcium Carbonate is the food-grade calcium source with the highest calcium content on the market. Each unit dosage provides abundant calcium nutrition to efficiently fulfil calcium-fortification targets for national-standard-compliant formulas, serving as the preferred raw material for basic nutritional fortification.
Heat-resistant, extrusion-resistant and drying-processing-resistant. Resists decomposition and failure during baking, extrusion-puffing, granulation and freeze-drying. Stable processing performance suitable for large-scale industrial production.
Pure-white and tasteless with fine uniform powder texture. Generates no off-odours and does not alter product base colour after compounding. Does not compromise taste or appearance of baked goods, meal-replacement products and compressed tablets, well-suited for basic clean-label formulas.
Releases bio-available calcium ions upon dissociation under gastric-acid conditions, consistent with human natural digestion-absorption mechanism. Meets daily basic dietary calcium-supplement demands for general-population nutritional supply.
Freely compoundable with vitamin D, vitamin K2, magnesium, zinc, iron, dietary fibre and sugar alcohols. Compatible with full-range multi-vitamin-mineral formulas without antagonistic reactions with conventional ingredients.
Mature and stable raw-material supply with controllable cost and sufficient inventory. Suitable for large-scale regular nutritional fortification addition in food industry, and is the preferred universal calcium-supplement base material.
Calcium Carbonate is a safe, compliant and well-established basic inorganic-calcium nutritional fortifier widely applied for daily dietary calcium supplementation:
Supplies high-concentration bio-available calcium, participates in mineralisation and formation of human bones and teeth, elevates bone mineral density, prevents calcium loss and maintains normal physiological structure of bones and teeth.
Calcium ions take part in physiological processes including nerve conduction, muscle contraction and body-fluid balance. Continuous dietary calcium supplementation sustains normal human metabolism and physiological homeostasis.
Safe, compliant and widely applicable. Satisfies daily basic calcium-supplement requirements for children, adults and middle-aged & elderly groups, supporting regular nationwide dietary nutritional fortification.
Its safety has been long-validated by market practice. Suitable for long-term continuous addition in foods to realise nationwide basic dietary calcium supplementation and nutritional conditioning.
➢Cereal & Bakery Products
Bread, cakes, biscuits, puffed foods: Stable under high-temperature processing for calcium fortification without impairing baking colour and taste.
Cereal flakes, cereal powders, meal-replacement powders: Mainstream basic calcium source with strong powder compatibility for uniform and stable reconstitution.
➢Solid Beverages & Powdered Foods
Solid beverages & reconstitutable powders: Good flowability and dispersibility for multi-vitamin-mineral fortification formulas.
Meal-replacement dietary powders & nutritional powders: Cost-effective calcium fortification to guarantee compliance with product nutritional indicators.
➢Confectionery & Snacks
