Key Features
≥99.0% assay improves formulation consistency in buffered vitamin systems
PH controlled at 7.0–8.0 reduces acidity impact in sensitive beverage formulations
≤0.25% moisture improves powder stability during storage and transportation
Sodium content controlled at 11.0–13.0% improves batch consistency in fortified products
40–100 mesh particle distribution improves premix blending uniformity
Fast dissolution performance improves processing efficiency in liquid systems
Manufacturing & Quality Control
Neutralization Process Control
Reaction temperature is controlled at 35–45°C during sodium salt conversion to stabilize assay consistency and reduce unreacted residue.
Purification Management
Multi-stage filtration and decolorization reduce insoluble impurities and improve powder color consistency.
Crystallization Precision
Controlled crystallization improves particle uniformity and reduces excessive fine powder generation during processing.
Drying Parameters
Low-temperature drying maintains final moisture at ≤0.25% to reduce oxidation and improve storage stability.
Sodium & Impurity Monitoring
Sodium content, oxalic acid, and heavy metals are monitored throughout production to support food and supplement application requirements.
Batch Verification
Each batch is tested for assay, moisture, sodium content, oxalic acid, heavy metals, and microbiological compliance before shipment.

FAQ
Q: What is the difference between Sodium Ascorbate and Ascorbic Acid?
A: Sodium Ascorbate is a buffered form of vitamin C with lower acidity, commonly used in formulations sensitive to low pH conditions.
Q: Is the product suitable for beverage applications?
A: Yes. Fast dissolution and buffered pH performance improve compatibility with beverage premix systems.
Q: How is oxidation controlled during production?
A: Low-temperature drying and controlled moisture management are applied to reduce oxidation during processing and storage.
Q: How is powder consistency maintained between batches?
A: Crystallization and screening parameters are controlled to stabilize particle distribution and bulk density.
Q: Can low microbiological specifications be supported?
A: Yes. Controlled production and packaging environments can support low microbial requirements for regulated manufacturing applications.
Q: Can OEM retail packaging be supplied?
A: Yes. OEM bottles, pouches, labels, and export cartons can be customized according to customer branding requirements.
Q: What export documents can be provided?
A: COA, MSDS, TDS, assay reports, and third-party inspection documents can be supplied for export shipments.
