Product Info
What is Milk Calcium?
Milk Calcium is a natural mineral complex composed mainly of calcium and phosphate extracted from milk, used primarily as a dietary supplement or food fortifier to support bone health.
How is Milk Calcium made?
| Step No. | Production Stage | Key Action | Control Point & Note |
|---|---|---|---|
| 1 | Raw Milk Reception | Receive and inspect fresh, high-quality milk. | Control Point: Test for antibiotics, microbial count, fat, and protein content. Note: Only milk meeting strict quality and safety standards is accepted for processing. |
| 2 | Separation & Pasteurization | Separate cream to produce skim milk, then pasteurize the skim milk. | Control Point: Pasteurization temperature and time (e.g., 72-75°C for 15-20 seconds). Note: This step ensures food safety by eliminating pathogens and prepares the milk for the next stage. |
| 3 | Casein Precipitation | Add food-grade acid or enzymes to the skim milk to precipitate the casein protein. | Control Point: Precise monitoring and control of pH (typically to ~4.6) and temperature. Note: This causes the milk to separate into solid casein curd and liquid whey, which contains the soluble calcium. |
| 4 | Whey Separation | Mechanically separate the liquid whey from the solid casein curd. | Control Point: Efficiency of decanters or separators. Note: The collected whey is the primary raw material for milk calcium extraction. |
| 5 | Filtration & Purification | Pass the whey through a series of filtration systems, typically Ultrafiltration (UF). | Control Point: Membrane pore size, transmembrane pressure, and temperature. Note: This process concentrates the calcium and phosphorus complex while removing lactose, water, and other minerals. |
| 6 | Evaporation | Gently remove water from the purified liquid under vacuum to increase its solid content. | Control Point: Temperature and vacuum level. Note: This creates a concentrated slurry (typically 40-50% solids) suitable for drying without damaging the mineral complex. |
| 7 | Spray Drying | Atomize the concentrated slurry into a chamber of hot air. | Control Point: Inlet and outlet air temperatures and atomization pressure. Note: The water evaporates instantly, forming a fine, free-flowing powder of milk calcium. |
| 8 | Sieving & Blending | Sieve the powder to ensure uniform particle size and blend different batches for consistency. | Control Point: Sieve mesh size and blender mixing time. Note: This ensures the final product meets customer specifications for physical properties like bulk density and solubility. |
| 9 | Metal Detection & Packaging | Pass the finished powder through a sensitive metal detector and package it into sealed, food-grade containers. | Control Point: Regular calibration and testing of the metal detector. Note: Packaging occurs in a hygienically controlled environment to prevent contamination. |
| 10 | Final QC & Release | Test samples from the final packaged product. | Control Point: Laboratory analysis of calcium content, phosphorus ratio, microbial load, heavy metals, and moisture. Note: The batch is held in quarantine and only released after passing all quality specifications. |

Applications & Usage
Common Applications:
Fortification in infant formula
functional foods
beverages
supplements
clean‑label products
Mechanism of action:
| Parameter | Milk Calcium |
|---|---|
| Functional Category | Nutrient Fortificant; Texture Stabilizer; Firming Agent; Opacifier. |
| Key Ingredients | Calcium Phosphate (primarily as amorphous Tricalcium Phosphate and Hydroxyapatite); Milk Minerals. |
| Mechanism of Action | Provides a bioavailable source of calcium and phosphorus for nutritional enrichment. Divalent calcium ions (Ca2+) form ionic bridges between anionic polymers (e.g., pectin, alginate) or protein micelles (e.g., casein), strengthening gel networks and increasing firmness. Acts as a mineral complex that buffers pH and contributes to opacity. |
| Application Effect in Product | Enables nutritional claims for calcium content in beverages, dairy, and supplements. Improves firmness and reduces syneresis in yogurts and cheeses. Enhances structure and mouthfeel in fortified foods. Increases opacity and whiteness in low-fat applications. Provides a neutral, non-chalky taste profile compared to other calcium sources. |
Comparison:
| Product Name | Category/Type | Key Features | Strengths (vs peers) | Weaknesses (vs peers) | Best Use Cases | Why Choose |
|---|---|---|---|---|---|---|
| Milk Calcium | Food-Derived Calcium Supplement | Derived from cow's milk; contains calcium phosphate and other milk minerals. | Natural food source; balanced mineral profile (calcium and phosphorus) similar to bone; good bioavailability. | Contains dairy allergens (lactose); not suitable for vegans; more expensive than mineral salts. | General bone health for individuals who tolerate dairy and prefer a food-based supplement. | For a natural, well-absorbed calcium source that mirrors the mineral composition of human bones. |
| Calcium Carbonate | Mineral Salt Supplement | Highest concentration of elemental calcium (40%); typically sourced from limestone or oyster shells. | Highest dose per tablet; most affordable and widely available. | Requires stomach acid for absorption (must be taken with food); may cause gas or constipation. | Healthy individuals on a budget needing high doses of calcium who have no digestive issues. | For the most cost-effective, high-potency calcium option. |
| Calcium Citrate | Mineral Salt Supplement | Bound with citric acid; contains 21% elemental calcium. | Can be absorbed without stomach acid (taken with or without food); gentler on the digestive system. | Lower elemental calcium per tablet (requires more pills); more expensive than carbonate. | Older adults, individuals with low stomach acid, or those taking acid-reducing medication. | For superior absorption and fewer digestive side effects, especially if stomach acid is low. |
| Plant-Based Calcium (Algae) | Food-Derived Calcium Supplement | Sourced from marine algae; provides calcium, magnesium, and other trace minerals in a porous structure. | Vegan, sustainable, whole-food source; multi-mineral complex may offer synergistic benefits for bone health. | Significantly more expensive; lower elemental calcium percentage than carbonate. | Vegans, individuals with dairy allergies, or those seeking a complete multi-mineral complex from a natural source. | For a vegan, whole-food supplement that includes other bone-supporting minerals. |
