✅Clinical Nutrition – Gentle calcium source for medical foods
❓ "What's the optimal calcium fortification level for almond milk?"
→ Recommended protocol:
• 120mg/100mL (matches dairy milk calcium)
• Pre-dissolve in warm water (50°C) before blending
• Stabilize with 0.1% gellan gum to prevent sedimentation
• Retains 95% calcium after 6-month shelf life
❓ "How to prevent protein coagulation in soy milk?"
→ Technical solution:
✔ Use calcium gluconate instead of carbonate
✔ Gradual addition at <40°C with agitation
✔ Maintain pH >6.5 during fortification
❓ "Can calcium gluconate create clear fortified juices?"
→ Clarification method:
• 0.05μm filtration after dissolution
• Chelate with 0.01% citric acid
• Dosage: Up to 150mg Ca/100mL remains crystal clear
❓ "Your solution for calcium-fortified carbonated drinks?"
→ Formula adjustment:
• pH control between 3.0-3.5
• Combine with 0.1% potassium gluconate
