Quality & Certifications

Certified excellence,
at every stage.

Four international standards. Three-stage process control. One promise — every batch we ship is fully traceable, fully tested, and fully specified.

International Standards

Our certifications

ISO 9001

Quality Management

Certified since 1999. Our QMS ensures consistent product quality, measurable customer satisfaction, and a culture of continuous improvement.

ISO 14001

Environmental

Sustainable operations: water-recycling loops, waste-heat recovery, and stringent emissions monitoring minimize our environmental footprint.

GMP

Good Manufacturing

Strict hygiene controls, documented SOPs, and full batch traceability — the standard required for food-grade and pharmaceutical-grade production.

HACCP

Food Safety

Hazard analysis & critical control points — seven principles applied to every food-grade starch and sweetener batch, from corn intake to sealed pallet.

Our Process

Three-stage quality control

Every kernel is tested before it enters the mill. Every pellet is tested before it leaves the warehouse.

1

Raw Material Inspection

All incoming corn is sampled and tested for moisture, starch yield, mycotoxin levels, and foreign contaminants. Only lots that meet our specification enter the steeping tanks.

  • Moisture & test-weight
  • Aflatoxin screening
  • Pesticide residue panel
2

In-Process Monitoring

Real-time sensors and hourly lab sampling at every critical control point — steeping, germ separation, fine grinding, dewatering, and drying — feed back into the DCS for immediate correction.

  • pH & SO₂ tracking
  • In-line viscosity
  • Moisture probes
3

Final Product Testing

Every lot is released only after full-panel analysis in our accredited lab. A Certificate of Analysis accompanies every shipment, with retained samples kept for traceability.

  • Full spec panel (CoA)
  • Microbiological release
  • Retained samples

Advanced Testing Capabilities

A laboratory built for scrutiny.

Our in-house quality laboratory is equipped with imported analytical instruments and staffed by a dedicated team of chemists. From amino-acid profiling to heavy-metal detection, every specification on our Certificate of Analysis is verifiable in-house.

Viscosity & Rheology

Brabender, RVA, and rotational viscometers for starch paste behaviour.

Protein & Moisture

Kjeldahl, Dumas combustion, and halogen moisture analysers.

Microbiological Screening

Total plate count, yeast/mould, Salmonella, E. coli, coliforms.

Heavy Metals & Contaminants

ICP-MS for Pb, As, Cd, Hg; HPLC for mycotoxins & pesticides.

Amino Acid Profiling

HPLC quantification of lysine isomer purity and residual nutrients.

Polymer Characterisation

MFI, DSC, tensile strength for PLA and modified-starch materials.

Our Quality Policy

Persisting in science,
contributing first-class quality,
maintaining high starting points
and standards.
