Fortification — Process Challenge

Food Fortification Minerals: Calcium, Iron, Zinc & Magnesium Salts for Hitting Label Values

Fortified foods must reach declared calcium, iron, zinc and magnesium content without sourness, astringency or off-taste; need soluble mineral salts
Why It Matters
Fortified foods must reach declared calcium, iron, zinc and magnesium content without sourness, astringency or off-taste; need soluble mineral salts
Solution Approach

Fortified foods must reach declared calcium, iron, zinc and magnesium content without sourness, astringency or off-taste; need soluble mineral salts RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.

Typical Formulation Workflow
1
Process & Compliance Review
Map the application and contact points, and confirm food-grade and regulatory status (FCC/USP, Kosher/Halal, allergen) for every input.
2
Ingredient & Grade Selection
Select the right grade of acidulant, preservative, emulsifier, stabilizer, or processing aid for the formulation, label, and sensory targets.
3
Bench Trial & Dosing
Validate use level and performance in a bench or pilot batch, and specify packaging and lot traceability suited to food-safety requirements.
4
Quality & Shelf-Life Validation
Verify finished-product quality, microbial stability, and shelf life, and lock the spec with a CoA and document control for audits.
