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 Treatment Workflow
1
System Assessment
Characterize operating conditions—fluid composition, temperature, pressure, flow rates—and benchmark current treatment performance.
2
Chemistry Selection
Match base chemicals to your operating envelope. Factor in compatibility with existing programs, regulatory constraints, and downstream impacts.
3
Dosage & Delivery
Determine optimal treat rates through jar testing or field trials. Configure packaging (drums, totes, ISO tanks) to match consumption and storage logistics.
4
Monitoring & Adjustment
Track KPIs—coupon rates, residuals, separator performance, water quality. Adjust chemistry and dosage as conditions change.
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)
