Quality control

We test raw and packaging materials, intermediates and finished products throughout the process, and keep checking quality through regular stability tests until the expiry date.

Tests

  • General analysis

    • Physicochemical tests
    • Harmful substances (heavy metals, etc.)
    • Functional ingredient analysis (vitamins, minerals, etc.)
  • Microbiological tests

    • Coliform, E. coli, total bacteria and fungi counts
    • Lactic acid bacteria test
  • Process control

    • Incoming material inspection and testing
    • Process control testing and verification
    • Workplace environment control
    • Hazard control
  • Product inspection

    • ICP and HPLC analysis
    • Microbial analysis
    • Stability tests
    • Efficacy verification

We improve quality by repeating the four PDCA stages

  1. Plan

    Risk assessment, strategy and resource analysis

  2. Do

    Training, documentation, calibration

  3. Check

    Internal inspection, process monitoring, deviation and change control, process verification, product quality evaluation

  4. Act

    Immediate improvement, preventive action, update of procedures

Process control equipment

  • Automatic tablet sorter

    Detects visual defects in tablets automatically and sorts out rejects.

  • X-ray inspection machine

    Uses X-rays to inspect for and remove dense, hard foreign matter such as Fe, SUS and plastic.

  • Metal detector

    Uses a magnetic field to inspect for and remove ferrous (Fe) and non-ferrous (Cu, SUS, etc.) metal.

  • Checkweigher

    Sets a weight range for tablet and powder-filled products and sorts out underweight and overweight ones.
