Why It Matters
Commercial and wholesale bakeries dose propionates at the mixer to extend the shelf life of bread, tortillas and cake against mold and rope-forming bacteria — a staple bulk ingredient bought continuously. Propionates work in the near-neutral pH range of bakery dough, where benzoate/sorbate acidic-food systems are less effective
Solution Approach
Commercial and wholesale bakeries dose propionates at the mixer to extend the shelf life of bread, tortillas and cake against mold and rope-forming bacteria — a staple bulk ingredient bought continuously. Propionates work in the near-neutral pH range of bakery dough, where benzoate/sorbate acidic-food systems are less effective 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.
Recommended Chemistries (4)
Calcium Propionate
CAS 4075-81-4
Releases propionic acid at bakery pH; the undissociated acid inhibits mold and rope-forming Bacillus while the calcium adds a minor fortification — the dominant bread preservative

Propionic Acid
CAS 79-09-4
Acids & Salts
Biocidal Action
1848 (PROPIONIC ACID) · Class Lipophilic weak acid that penetrates microbial cells and lowers internal pH; the free-acid form for liquid dosing (catalog currently holds propionic anhydride only)
Melting Point: -22 °C Boiling Point: 141 °C at 760 mmHg Density: 0.995 at 20 °C
Full Details
Sodium Propionate
CAS 137-40-6
Highly soluble propionate salt giving the same antifungal action where calcium fortification or grittiness is unwanted
Full Details
Sodium Diacetate
CAS 126-96-5
Acids & Salts
pH Adjustment
Acetic-acid donor providing complementary mold/rope suppression and dough pH buffering
Solubility: SOLUBILITY IN WATER: 1 G/ML PH: 4,5-5,0 (10 % aqueous solution)
