Mineral
Highly-Adaptable Mild-Type Base Material for Food Calcium Fortification
Calcium Citrate is an organic-calcium nutritional fortifier refined by complexation of citric acid and calcium salts. It is a universally-approved calcium source complying with GB 14880, applicable to full-range food categories and special-diet systems. Different from inorganic calcium sources, it features favourable solubility, low gastric-acid dependence, mild absorbability and low lithiasis risk. It has four core attributes: high absorption-utilisation rate, low gastrointestinal irritation, broad system compatibility and excellent stability. It is a high-end calcium-supplement base material with strong versatility for food and health-care product sectors.
Main Components: Tricalcium citrate, molecular formula Ca₃(C₆H₅O₇)₂, CAS No. 813-94-5
Core Specifications: Calcium content ≥21.0 %; heavy metals (lead, arsenic, cadmium) comply with limit values specified in GB 1903.17; loss on drying, sulphates, oxalates and other indicators meet regulatory requirements; customisable particle-size available.
Appearance: White crystalline fine powder, odourless and tasteless. Loose and uniform powder with excellent flowability, free of caking and impurities.
Stability: Stable physicochemical properties, heat-resistant, acid-alkali tolerant and resistant to processing denaturation; low moisture-absorption and caking tendency. Shelf-life: 24 months under sealed, cool and dry storage conditions.
Solubility: Slightly soluble in water, insoluble in ethanol. Dissociation and calcium-ion release take place under weak-acid and neutral conditions independent of gastric acid. Exhibits excellent compatibility with proteins, colloids, sugar alcohols, vitamins and minerals.
➢Regulatory: Complies with GB 1903.17-2016, listed as an approved nutritional-fortifying calcium source under GB 14880. Permitted for ordinary foods, complementary foods for infants and young children, special-diet foods and health foods with clean and compliant labelling.
➢Absorption: Organic-chelated calcium structure, dissociation does not require strong gastric acid. Absorbable both on empty stomach and after meals, with markedly higher bioavailability than inorganic calcium such as calcium carbonate.
➢Mildness: Weak alkalinity, free of gastrointestinal burdens such as bloating, constipation and heartburn. Excellent tolerability for sensitive populations including the elderly, children and pregnant-lactating women.
➢Formulation Suitability: Versatile for both solid and liquid dosage forms. Heat-resistant during processing; does not impair product flavour, colour or transparency, and generates no precipitation or turbidity.
➢Practicality: Stable calcium content, controllable dosage addition and high batch-to-batch consistency. Low tendency to form calculi via combination with oxalic acid and phosphoric acid, delivering high safety for long-term consumption.
Citrate-chelated structure reduces heavy reliance on gastric acid. Effective dissociation and absorption occur under weakly-acid and neutral gastrointestinal environments, slightly interfered by dietary dietary-fibre and phytic acid, achieving stable and efficient calcium supplementation.
Lower alkalinity compared with inorganic calcium sources. Gentle nature reduces incidence of abdominal distension, belching, constipation and other discomforts. Suitable for long-term dietary calcium supplementation for gastrointestinal-sensitive populations with superior eating experience.
Heat-resistant, acid-alkali tolerant and adaptable to hot-cold processing. Compatible with baking, extrusion-puffing, high-temperature sterilisation, freeze-drying and other processes. Resistant to precipitation and denaturation during processing for stable shelf-life quality.
Pure odour-free powder. No bitter-astringent taste, turbidity or precipitation upon compounding. Applicable to transparent beverages, dairy products, baked goods and solid powders without destroying original product colour and taste.
Low tendency to combine with oxalic acid in-vivo to form calcium-oxalate precipitates. Effectively lowers calculus risk induced by calcium supplementation, suitable for sustained long-term dietary calcium intake with superior safety versus conventional inorganic calcium sources.
Freely compoundable with vitamin D, vitamin K2, magnesium, zinc, iron, sugar alcohols and dietary fibre. Promotes calcium deposition and utilisation and improves overall formulation functionality.
Calcium Citrate is a safe and compliant high-end organic-calcium nutritional fortifier with high human-body adaptability and multiple physiological-maintenance values:
Efficiently supplies bio-available free calcium, participates in mineralisation and formation of bones and teeth, improves bone mineral density, prevents calcium loss and maintains bone toughness and dental health.
Calcium ions participate in human physiological activities including nerve conduction, muscle contraction and energy metabolism. Proper calcium supplementation maintains normal bodily metabolism and balanced physiological functions.
Lenient absorption conditions and minimal gastrointestinal irritation. Suitable for growth-phase calcium supplementation in children, nutritional supply for pregnant-lactating women and daily anti-calcium-loss maintenance for middle-aged and elderly groups.
Unique chelated structure mitigates in-vivo calcium-oxalate deposition, relieves metabolic burdens caused by long-term calcium intake and enables safe long-term dietary calcium supplementation.
➢Dairy Products
Milk powders, reconstituted milk, yoghurt: Gentle calcium fortification without impairing dairy-system taste and stability; prevents protein precipitation.
Plant-protein beverages: Compatible with neutral and weakly-acid drinks; achieves calcium fortification without turbidity or precipitation and preserves transparent beverage texture.
➢Cereal & Bakery Products
Cereal flakes, cereal powders, meal-replacement powders: Calcium fortification compounded with multi-vitamins-minerals; uniform powder with good reconstitution performance.
Bread, cakes, biscuits, puffed foods: Stable nutrient retention under high-temperature processing, enhances health-added value of finished goods.
➢Beverages
Functional drinks, fruit-vegetable juices, sparkling water: Suitable for transparent-system formulations; calcium fortification brings no turbidity or off-odours.
Solid beverages & reconstitutable powders: Good flowability and dispersibility, ideal for high-end clean-label calcium-supplement formulas.
➢Confectionery & Snacks
Gummies, compressed candies, jellies: Calcium nutritional fortification with pure non-astringent taste for high-end functional snacks.
Cereal bars & energy bars: Stable calcium fortification, suitable for ambient-temperature storage with consistent shelf-life quality.
Children’s calcium-supplement tablets, bone-health dietary powders for middle-aged and elderly consumers, multi-nutrient calcium supplements for pregnant-lactating women, sports-nutrition foods. It serves as the preferred calcium source for high-end functional calcium-supplement products.
Organic-calcium additive for high-grade livestock-poultry, aquaculture and pet feeds. Improves animal calcium absorption, boosts skeletal development and reduces metabolic burdens.
