Manufacturing & Quality Control
Fermentation Process Control
Fermentation temperature is controlled at 30–34°C and pH at 6.8–7.2 to stabilize amino acid conversion efficiency and reduce impurity formation.
Purification Management
Multi-stage filtration and decolorization reduce insoluble particles and improve powder whiteness consistency.
Crystallization Precision
Controlled cooling crystallization improves crystal uniformity and reduces excessive fine powder generation.
Drying Parameters
Continuous drying maintains final moisture at ≤0.5% to improve flowability and reduce lump formation during storage.
Particle Size Screening
Vibration screening controls mesh size distribution within 80–100 mesh for stable blending and automatic packaging performance.
Batch Verification
Each batch is tested for assay, moisture, chloride, heavy metals, residue on ignition, and microbiological compliance before shipment.
