Quality Assurance Protocol

1. Input Control

• Certified organic seeds (where applicable)
• Pharmaceutical-grade nutrient salts (USP/EP certified)
• Reverse osmosis water (conductivity <10 µS/cm)
• Environmental monitoring (ISO 14644 cleanroom standards for post-harvest)

2. In-Process Monitoring

• Daily: pH, EC, dissolved oxygen, temperature, humidity
• Weekly: Nutrient solution analysis (ICP-MS for 16 elements)
• Bi-weekly: Plant tissue analysis (verify nutrient uptake)
• Continuous: Automated sensors with alarm thresholds

3. Harvest & Post-Harvest

• Aseptic harvesting techniques (trained personnel, hairnets, gloves)
• Immediate cooling (2-4°C within 30 minutes)
• Controlled drying (40-50°C for heat-sensitive compounds, 60-70°C for stable compounds)
• Freeze-drying option (preserving volatile compounds)

4. Analytical Testing (per batch)

• HPLC Analysis: Active ingredient quantification (±5% specification)
• Microbiology: Total aerobic count, yeast/mold, coliforms, pathogens (USP <61>/<62>)
• Heavy Metals: ICP-MS screening (lead, arsenic, cadmium, mercury - ICH Q3D limits)
• Pesticide Residue: Multi-residue screen (>400 compounds - EU MRL limits)
• Aflatoxins: If applicable (EU limit: 2 µg/kg total aflatoxins)

5. Certificate of Analysis (COA)

• Batch number, harvest date, test date
• Active ingredient assay results
• Microbiology results
• Heavy metal results
• Pesticide residue: “Not Detected” (LOQ: 0.01 mg/kg)
• Signed by Quality Manager, released by QA Director
