Manufacturing & Quality Control
Fermentation Process Control
Fermentation temperature is controlled at 30–35°C and pH at 6.0–7.0 to stabilize precursor conversion efficiency and reduce by-product generation.
Purification Management
Multi-stage purification and activated carbon treatment reduce insoluble impurities and improve powder color consistency.
Crystallization Precision
Controlled cooling crystallization improves particle uniformity and reduces excessive fine powder generation.
Drying Parameters
Low-temperature drying maintains final moisture at ≤0.4% to reduce oxidation risk during storage and transportation.
Impurity Monitoring
Heavy metals and oxalic acid are monitored throughout production to support food and supplement application requirements.
Batch Verification
Each batch is tested for assay, moisture, oxalic acid, heavy metals, residue on ignition, and microbiological compliance before shipment.
