Preservation — Process Challenge

Ascorbic Acid & Erythorbate for Oxidation and Color Loss

Dissolved oxygen oxidizes pigments and degrades ascorbate in juice, beer and cured meats, dulling color and flavor; need reducing agents that preferentially consume oxygen
Why It Matters

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)
Ascorbic Acid (Vitamin C), Food Grade
CAS 50-81-7
Acids & Salts
Preservation
Ascorbic acid scavenges dissolved oxygen and regenerates other antioxidants, protecting color and flavor in juice, beer and cured systems
Melting Point: 190–192 °C (decomposes)   Density: 1.65   Solubility: ≥ 100 mg/mL at 23 °C
Full Details
Erythorbic Acid (FCC)
CAS 89-65-6
Specialty Additives
Preservation
The ascorbic stereoisomer is used purely as an oxygen scavenger and cure accelerator where vitamin function is not required
Melting Point: About 164 °C to 172 °C with decomposition   Solubility: Soluble in alcohol, pyridine; moderately solubl…

Sodium Erythorbate (FCC)
CAS 6381-77-7
Specialty Additives
Preservation
Soluble erythorbate speeds nitrite cure-color development and blocks oxidative browning in processed meats
Melting Point: 154–164 °C (decomposes)   Density: 1.2   Solubility: ≥ 100 mg/mL at 18 °C
Full Details
Calcium Ascorbate (USP/FCC), Granular
CAS 5743-28-2
Specialty Additives
Preservation
Non-acidic calcium ascorbate delivers antioxidant function in dips and dry blends that would be too tart with free ascorbic acid
PH: Between 6,0 and 7,5 (10 % aqueous solution)
